EGE-Elektronik launches MGK magnetic sensors for use in cryogenic processes in medical technology and beyond. Based on the MGK series, the sensors were specifically designed for continuous operation at low temperatures down to -80 °C. The manufacturer specialized in robust sensor technology for demanding applications offers very short response times for the application-specific adaptation of sensors featuring, for example, increased protection classes, interfaces according to customer requirements or, as here, special materials that can withstand dry cryogenic atmospheres over the long term. The MGK magnetic sensors are tripped when a magnetic contact comes near them. They are suitable, for example, for detecting, counting or positioning transport containers, flaps, doors or valve positions. The sensing distance is 5…20 mm, depending on the flux density of the magnet. The use of magnetic sensors enables increased sensing distances even at extreme temperatures and temperature profiles that challenge inductive sensors. They also detect objects through non-magnetic materials such as plastic walls.

EGE-Elektronik has launched a new flow measurement system with a separate evaluation unit and an IO-Link interface. The ST 55 S sensor detects flow velocities from 0.05 m/s to 3 m/s and temperatures from 0 °C to 80 °C in liquid media. The 47 mm, 80 mm or 120 mm long probe is installed in pipelines with internal diameters from 15 mm to 250 mm. Optimally matched to the probe, the SNA 552 GAPL evaluation electronics calculates the flow rate, displays it in l/min or mł/h and can transmit it to a PLC via IO-Link. The easy-to-read display can be tilted and turned upside down. Users can conveniently parameterize the measuring points via buttons on the housing or via IO-Link. The stainless-steel electronics unit features IP65 protection and is suitable for ambient temperatures from -10°C to 60°C. It is connected to the sensor via an up to 5 m long cable with an M12 plug. In addition to IO-Link, the evaluation electronics unit features independently configurable switching outputs or a current output. Functions such as min/max/average memory as well as fault monitoring and access level management are integrated directly into the device. Special operating modes such as hysteresis or dosing ensure optimal function in various applications. The manufacturer also offers the right accessories for mounting and integration into IO-Link networks.

EGE expands its range of IO-Link sensors, launching an entire new series of flow sensors for smart networking in compact plants and systems. The new SDNB 552 series is based on a tried and tested special model. Four series sensors measure the flow velocity and temperature of water-based liquids in ranges between 0.5…10 l/min and 5…100 l/min with linearized measured value output. The IO-Link interface allows for convenient remote sensor parameterization and data read out for maintenance. The analog output and switching output are available in SIO mode. Parameterization with IO-Link via the M12 connection is carried out either via a PLC or an IO-Link master – EGE offers the IOL Master Set V1.1 for this purpose. The sensors featuring G1/2 or G3/4 connection threads are designed for inline mounting in hoses and pipes. Based on the calorimetric measuring principle, the sensors introduce no moving parts or deflectors into the stream. The wetted parts are made of 1.4571 stainless steel. The sensors are IP65-rated, pressure-resistant up to 10 bar and designed for media temperatures from 0 °C to 60 °C. Due to their rugged design, EGE flow sensors withstand moisture and vibrations.

EGE presents new air flow controllers with an IO-Link interface and additional temperature measurement. The sensors for gaseous non-explosive media are available in two designs: LN 520 GPL with a smooth sleeve with a 20-mm diameter and LG 518 GPL with a male M18x1 thread. They measure flow velocities from 0.5 to 15 m/s and temperatures from -20 °C to 70 °C. Limit values and additional operating parameters can be freely set via the IO-Link interface. The sensors store minimum and maximum values onboard. Color LEDs on the cable outlet signal the flow state, the reaching of set limit values and connection to an IO-Link primary, or support visual identification in larger systems by flashing. For further processing in SIO mode, the PNP switching output is available – and in IO-Link mode, the process data with measured values for flow and temperature. The flow value is output in non-linear proportion to the air flow. The air flow controllers feature IP67 protection and fulfill the current IO-Link specification V 1.1.3. Reaction times are in the range of 2 to 20 s for flow changes and <15 s for temperature changes. The LN 520 GPL model with a smooth sleeve is supplied complete with a mounting flange.

The IGMF 202 GSP inductive proximity switch from German manufacturer EGE is an excellent fit for demanding applications with limited installation space and ambient temperatures between -5 °C and 120 °C. Due to its slim stainless-steel housing with a male M8 thread, the IGMF 202 GSP can also be mounted in places for which conventional models are too large. The flush design version of the temperature-change-resistant proximity switch features a sensing distance of 2 mm for ST 37 steel. A special plastic light element at the cable outlet visually signals object detection with a yellow light. Thanks to its waterproof housing, the proximity switch qualifies for car washes and other applications with regular cleaning. The sealing concept is also suitable for use in oil-laden environments. The sensor is operated with a DC voltage between 10 V and 30 V. EGE supplies it with a two-meter FEP cable by default.

EGE announces the new LC 521 GSP-EX22 series of ATEX-certified screw-in airflow monitors with G1/2 thread for easy parameterization. The stainless-steel category 3 sensors have a 0.5 m/s to 20 m/s detection range. They are suitable for flow monitoring of gaseous media in zone 2 and 22 hazardous areas. They are installed in supply or exhaust air ducts with a screw adapter with a G1/2 female thread. The sensors are available in lengths of 32 mm, 49 mm, 101 mm or 151 mm. In applications with a specified air flow, users can easily set the limit value via the integrated potentiometer. The flow state is indicated by a three-color light on the housing front and transmitted for further processing by a PNP switching output. When the limit value is exceeded, the light changes from red to yellow, a further increase in the flow velocity is signaled by a green light. All variants have an IP67 protection rating and can be used in ambient temperatures between -10 °C and 60 °C. They are connected via a 2 m long fixed PUR cable. The sister series LC 518 GSP-EX22 comprises 80 mm long airflow monitors with an M18 thread.

EGE now also supplies the intrinsically safe inductive sensors IGEXa, IGEXHa, IGEXPa and IGEXUa as well as the evaluation device IKMb 122 Ex as versions certified according to CSA. The ruggedized proximity switches for metal detection are approved for use in zones 0 and 20 areas with potentially explosive atmospheres (HazLoc). They are available in M12, M18 and M30 standard designs. IGEXHa and IGEXPa are two sensors that withstand high-pressure cleaning and ambient temperatures up to 140 °C and down to -60 °C respectively. The corresponding IKMb 122 Ex evaluation device with a compact 22 mm wide DIN-rail housing for galvanic isolation and evaluation is installed in a control cabinet outside hazardous zones. Green, yellow and red LEDs on the housing front indicate the operating states of the connected proximity switch.

SZAb evaluation devices from EGE for ATEX-certified ST and STS flow monitors are now available with an IECEx approval. These devices feed sensors installed in hazardous environments. They have an intrinsically safe circuit, galvanically isolated from the signal output and mains supply and are mounted in a control cabinet outside areas with potentially explosive atmospheres. For application-specific signaling, the evaluation devices are available with relay or analog 4…20 mA outputs. The relay output versions allow users to set switch-off delays of up to 25 seconds. Limit values for all models are simply set via a potentiometer on the front of the device. A multi-color LED line indicates the flow tendency. A red LED light indicates that the default limit value is not reached and the switching output is not active. A yellow LED indicates that the limit value has been reached and the output is switched. In addition, four green LEDs show by how much, relatively, the limit value is being exceeded. To avoid unnoticed defects, the evaluation devices feature cable breakage and short-circuit monitoring functions. The analog output version requires a 24 V DC power supply. Models with a relay output are also available for 230 V AC or 115 V AC operation.

The new ATEX-certified airflow monitors from the LC 518 GSP-EX22 series from EGE are used for flow monitoring of gaseous media in exhaust and supply air lines that require category 3 sensors. The stainless-steel sensors are designed for a 0.5 m/s to 20 m/s detection range. In applications with a specified air flow, users can easily adjust the limit value during operation via an onboard potentiometer. The flow state is indicated by a three-color light on the housing front and transmitted for further processing by a PNP switching output. When the limit value is exceeded, the light changes from red to yellow, a further increase in the flow velocity is signaled by a green light. The 80 mm long sensors are mounted directly in the wall of the ventilation duct with mounting nuts included in the scope of delivery. The M18 thread, which runs over the entire length of the housing, allows optimal positioning at different wall thicknesses. If the airflow is sufficient in the edge area, the measuring surface can be installed on a level with the inner wall of the duct. The sensors are designed in protection class IP67 and connected via a 2 m long PUR cable.

EGE expands its range of explosion-proof flow sensors, adding the new LC5 GA EX22 series of extremely robust airflow monitors for use in zone 2 and 22 environments with potentially explosive gas or dust atmospheres. The ATEX-certified, intrinsically safe and encapsulated airflow monitors in IP67 stainless-steel housings are available with M18 or G1/2 threads. They detect airflows at speeds from 0.5 m/s to 20 m/s with response times <5 s. For accurate adjustment at a given flow velocity, the devices feature a potentiometer screw and a two-color LED on the front side. Red, green and flashing lights signal when the minimum or maximum output current in a standard signal range 4...20 mA have been reached. LC5 GA EX22 airflow monitors are designed for use in temperature ranges from -10 °C to 60 °C and come with a two-meter fixed PUR cable by default. EGE supplies the devices with longer cables on request.

Launching the new multifunctional IO-Link converter IOL-KONV-UIS-01, EGE presents a compact and simple solution for noise-free digital signal transmission from conventional sensors via IO-Link. Depending on its configuration, the converter registers up to two analog values (0…10 V, 4…20 mA) or switching signals from the connected sensor, converts them into digital signals and transmits them to an IO-Link primary device. In addition to the digital output for process data transmission, the device has a second, analog output for programmable current or switching signals. All conventional sensors from EGE and other manufacturers can be connected to the converter, regardless of operating principles and measured values. The IO-Link converter offers additional monitoring functions. If the power consumption or operating voltage of the connected sensor deviate from recorded setpoints, for instance due to corrosion, the device sends an error message to the controller as an IO-Link event. To protect its own electronics, the converter features temperature monitoring, short-circuit detection and an adjustable shutdown function in case of overload. A front-end multicolor LED clearly shows the operating status. M12 connectors for sensors and IO-Link primary devices eliminate any cabling effort. The IP67-rated converter housing features lugs for flexible mounting near the sensor in all installation conditions. The converter is parameterized according to IO-Link Device Description V1.1 using an engineering tool connected via the IO-Link interface.

EGE provides IGEX20Pa-type proximity switches that withstand low temperatures down to -60 °C. ATEX- and IECEx-certified for use in Ex zones 0 and 20, these sensors can be used in hazardous areas with gas or dust atmospheres, for example in filling stations and facilities with gas pipelines etc. EGE now also offers easy-installation variants of these Polar-series proximity switches. Featuring the ignition protection type Ex m (encapsulation), these IGEX20Pa models can be employed in Ex zones 0 and 20 by themselves, without the need for additional switching amplifiers. EGE supplies the sensors with IP67 and IP68 ingress protection and in M12, M18, and M30 designs. Given a flush installation, the nominal switching distances are 2 mm, 5 mm, and 10 mm, depending on the design. The proximity switches are connected via a 2-m FEP cable. EGE supplies them with different cable lengths on request.

EGE designed its dynamic SDN 501/1 GSP-DYN flow controller to detect minimal pulsating flow rates from 0.02 ml. Suitable for most common liquids such as water, alcohol, oils, and fluid greases, the flow sensor is ideal for monitoring minimum lubrication or ensuring that the right amounts of chemicals or additives are metered out. Since the sensor operates according to the thermodynamic principle, it does not have any moving or corrosion-prone wear-and-tear parts. Due to its high sensitivity, it reacts to changing flow rates – caused for example by the actuation of a dosing piston – with extremely short reaction times of 0.1 s. The sensor’s built-in processing unit emits a switching signal for each detected pulse via a short-circuit-proof PNP-NO output and can hold the signal for up to 10 s. In addition, green and yellow LEDs on the housing front signal the detected pulses and the current device status. Manufactured from stainless steel and PBT, the robust sensors feature IP54 ingress protection and withstand pressures up to 10 bar. They are suitable for media temperatures between 0 °C and 80 °C. The units are operated with 24 VDC. They are fitted into pipes via a tube fitting or a G? thread and connected by means of an M12 connector. Mounting angles are available as accessories. The flow controllers‘ compact design enables parallel installation of several devices with different monitoring functions.

EGE introduces a new generation of level controllers with guided microwave: the MFN series sensors feature an IO-Link interface and thereby enable continuous access of PLCs to process and parameterization data. Using a corresponding master, the level controllers can be connected to any common bus system and conveniently parameterized via PC or notebook. The guided microwave measuring principle ensures high reliability due to its insensitivity to external influences such as temperature, pressure, or density. It provides for precise measurements in liquids such as water, oil, and emulsions as well as in viscous media. MFN sensors stand out due to their particularly short reaction times in case of level changes. Their display units can be configured to show the measured level in mm, cm, inch, liter, or percent. The housings can be rotated by 360° along with integrated LED indicators and control panels, allowing users easy access for configuring the devices and reading measured values. The level controllers feature IP67 ingress protection and are designed for an ambient temperature range of -25 °C to +85 °C. EGE’s level controller portfolio includes variants with coaxial, single, and double probes for use in different media. The company also manufactures probes from special materials such as Hastelloy or titanium for use in aggressive media. Moreover, EGE also adapts sensors to customer-specific tank geometries and difficult installation conditions, on request.

EGE has developed a new compact, rugged MDVH amplifier with enhanced sensitivity for its System 3000 industrial metal detector. The completely redesigned amplifier is characterized by higher adjustable sensitivity levels, reduced susceptibility to interference, and a more robust housing with IP67 ingress protection. Featuring automatic self-calibration, the unit works reliably even if the detector coil comes near metal fittings. Users can adjust the sensitivity of the detector coil as required via a rotary potentiometer on the housing front. The amplifier has a 260 x 160 x 90 mm wide aluminum housing. It is designed for an extended temperature range of -25 °C to +70 °C. EGE’s System 3000 is used in conveyor lines for noncontact detection of metal parts that could damage downstream machines or degrade the quality of bulk solids. Thanks to its rugged design, it is suited for outdoor use in harsh and dirty environments. The size of detected parts varies for different models. The MDVH unit is optimized for medium-sized parts such as nails, nuts, wire, or silverware. MDV series devices are designed to protect machinery by identifying larger metal parts such as excavation bucket teeth or parts of tools and enclosures.

Launching the IGEX20a inductive proximity switch, EGE presents a compact sensor with ignition protection type Ex m (encapsulation). Observing the relevant installation standards and conditions, it can be used directly in zones 0/20 without any further switching amplifier. IGEX20a is certified according to ATEX and IECEx. IECEx certification simplifies worldwide use of the sensors in member countries of the IECEx regime. Certified for use in Ex zones 0 and 20, the proximity switches can be employed in hazardous areas with gas or dust atmospheres, for example in gas stations and in facilities with gas pipelines etc. The switching function is indicated by an LED on the back of the device. The sensors are available in M12, M18, and M30 designs. Flush installation provided, the nominal switching distances are 2 mm, 5 mm, and 10 mm, depending on the design. The proximity switches are connected via a 2 m PUR cable. EGE supplies the sensors with different cable lengths on request.

EGE has extended its DGC line of hydrostatic level meters, adding a new sensor for measuring liquid media levels up to 20 m. The sensor consists of a measuring head with integrated electronics and an IP68 probe attached to a cable. The cable is up to 20 m long to ensure the probe can be lowered to the bottom of large tanks. The electronics unit is enclosed in a rugged stainless-steel housing with a G? thread for attachment, for instance on the tank cover. A line of LEDs integrated in the measuring head indicates the level at a glance. The sensor requires a 24 V DC supply. It can be used in ambient or media temperatures from -20 °C to +75 °C. Measured values are transmitted via a 4…20 mA output.

The intrinsically safe ATEX- and IECEx-certified proximity switches from EGE’s IGEXHa and IGEXPa series are suitable for use at extreme temperatures. IGEXHa inductive sensors withstand ambient temperatures of up to +140 °C. IGEXPa „polar“ models are suitable for down to -60 °C. Both series are approved for operation in zones 0/20. They feature IP69 ingress protection and are available in M12, M18, and M30 designs. Given a flush installation, the nominal switching distances are 2 mm, 5 mm, and 10 mm, depending on the design. The proximity switches are connected via a 2 m FEP cable. EGE supplies the sensors with different cable lengths on request. EGE also offers the IKMb 122 Ex series of suitable IECEx-certified signal processing units and intrinsically safe power supplies with programmable outputs. Internationally active machine builders benefit from the IECEx certification since it facilitates exporting products that integrate these proximity switches.

EGE offers to configure level controllers with guided microwave according to customer specifications. Based on its proven standard level gauge, the German manufacturer is able to adapt the sensors to suit various tank geometries, mounting conditions, or demanding media in no time. Options include angled probes that can be mounted on the side of tanks. EGE employs special materials such as Hastelloy or titanium to manufacture probes for use in aggressive media. EGE also specifically adapts the sensors to dielectric constants and to the temperature ranges of the liquid to be measured to ensure precise results in challenging media and cramped installation conditions.

EGE has extended its DGC line of hydrostatic level meters, adding a new sensor for measuring liquid media levels up to 20 m. The sensor consists of a measuring head with integrated electronics and an IP68 probe attached to a cable. The cable is up to 20 m long to ensure the probe can be lowered to the bottom of large tanks. The electronics unit is enclosed in a rugged stainless-steel housing with a G? thread for attachment, for instance on the tank cover. A line of LEDs integrated in the measuring head indicates the level at a glance. The sensor requires a 24 V DC supply. It can be used in ambient or media temperatures from -20 °C to +75 °C.

Launching the IGEX20a inductive proximity switch, EGE presents a compact sensor with ignition protection type Ex m (encapsulation). Observing the relevant installation standards and conditions, it can be used directly in zones 0/20 without any further switching amplifier. IGEX20a is certified according to ATEX and IECEx. IECEx certification simplifies worldwide use of the sensors in member countries of the IECEx regime. Certified for use in Ex zones 0 and 20, the proximity switches can be employed in hazardous areas with gas or dust atmospheres, for example in gas stations and in facilities with gas pipelines etc. The switching function is indicated by an LED on the back of the device. The sensors are available in M12, M18, and M30 designs. Flush installation provided, the nominal switching distances are 2 mm, 5 mm, and 10 mm, depending on the design. The proximity switches are connected via a 2 m PUR cable. EGE supplies the sensors with different cable lengths on request.

EGE now offers ATEX- and IECEx-certified signal processing units for the growing range of ATEX- and IECEx-approved two-wire sensors. IECEx certification greatly facilitates exporting the intrinsically safe sensors to many countries around the world – machine manufacturers and plant engineers will find it much easier to use such products in markets where they could not be used previously or required very tedious special certification. Type IKMb 122 Ex signal processing units connect to intrinsically safe EGE two-wire sensors for hazardous gas and dust atmospheres. They feature a space-saving, 22 mm wide DIN rail housing and are installed outside the hazardous area. Green, yellow, and red LEDs on the front side indicate the operating status and signal alarms if the integrated cable breakage detection or the short-circuit monitoring is triggered. The output can be set as normally closed or normally open.

Ultrasonic sensors from EGE’s AGVU-…H series for a 150..1500 mm detection range are extremely durable and fulfill the most demanding hygienic requirements. Featuring IP69K ingress protection, they allow for easy cleaning with high-pressure and steam-jet cleaners. This ensures optimum hygiene in food and beverage industry applications as well as, for instance, in medical and pharmaceutical production. The sensors can be used for fill-level detection, distance measurement, presence verification, or detecting and counting moving objects. They come in a rugged, fully encapsulated, gap-free stainless-steel housing. Depending on available installation space, two sizes can be selected: either D30 or the especially compact D18, with only 30 cm total length including the hygienic cable fitting. Integrated temperature compensation enables high measuring precision in the -20 °C to +70 °C range. A protective circuit ensures short-circuit strength and protection against polarity reversal. Versions with an analogue output (4..20 mA) are supplied with pre-set response curves, while models with a switch output allow for a quick and easy adjustment of the desired switching points via teach-in.

For applications where water vapor is prevalent, EGE introduces the IGMH…GSP-D series of inductive proximity switches with IP68/IP69K ingress protection that tolerate exposure to superheated steam. The sensors are designed for continuous operation in liquid or viscous media at temperatures from -25 °C to +140 °C. In dry processes, they even withstand temperatures up to 160 °C. They are therefore ideally suited for cooking processes in the food industry, including moving and positioning conveyors, sieves, baskets, and boilers. They can also be used in sterilization processes. The sensors‘ high thermal resistance is achieved through a special sealing technology between sensor and connector and a stainless-steel housing. This construction ensures high ingress protection. M12, M18, and M30 proximity switches with nominal switching distances between 2 and 15 mm are available. Thanks to their integrated electronics, they do not require a separate processing unit. They are connected via a 2-meter silicone cable. This sensor family is complemented by the IGMH…GSP-W and IGMH…GSP-L series, which provide high-temperature sensors that resist high-pressure cleaning in dry processes and silicone-free sensors for paint and powder-coating applications. The portfolio also includes the IGEXH sensor designed for up to +140 °C that can be installed in ATEX zones 0/20. In addition, EGE offers to develop and implement custom, application-specific sensor solutions with minimal lead times.

purpose sensor manufacturer EGE provides watertight inductive proximity switches for applications that require frequent cleaning. IGMH…GSP-W series waterproof high-temperature sensors achieve IP68/69K ingress protection and are easy to rinse off with high-pressure cleaners. They are therefore suitable for food industry applications such as monitoring of frying and baking lines, baking molds, or kiln cars. Thanks to their robust housing made of no. 1.4571 grade stainless steel and PEEK, they function reliably even when exposed to extreme ambient temperatures ranging from -25 °C to +160 °C. They are connected via a silicone cable.
