Many systems installed on rolling stock need reliable information about the current speed – from braking systems to drives to door locks. This information is usually provided by speed encoders installed on the vehicle axles. Up until now, additional encoders had to be installed, if other systems also required speed data. This proves difficult sometimes, due to space limitations at the axles. And of course, the installation incurs additional costs. Introducing the ProLine P 16000 pulse frequency conditioner, Knick Elektronische Messgeräte now provides an economical solution, which can reliably and accurately reproduce encoder signals. The SIL-2-compliant conditioner enables functionally safe decoupling of speed sensor signals as well as of standard signals. It converts these signals into galvanically isolated, analog 0/4…20 mA or 0…10 V standard signals that can be directly transmitted to the controller or other subsystems. The pulse input reproduces the measuring ranges 0…500 Hz or 0… 20 kHz with a =0.2 % full scale accuracy. The signal inputs are designed according to the SIL 2 safety integrity level so that there can be no unwanted impact on the signal source, which could distort measured values. Since pulse signals are directly converted into standard signals, there is no need for additional pulse counting inputs in the controller. Furthermore, safety-related standard signals from existing measuring circuits can be picked up and transmitted as electrically isolated signals. P 16000 complies with all standard requirements for use on rolling stock. It is highly resistant to harsh environmental conditions. Proper function of the device is unaffected by electromagnetic interference, extreme temperatures, vibrations, or shock impacts. The conditioner complies with current fire regulations for rolling stock according to EN 45525-2 and UL61010.

Due to the liberalization of the rolling stock market, more and more companies use the existing rail infrastructure. Trains are therefore equipped with energy measurement systems to track the power consumption of different operators and enable transparent billing. However, without reliable, highly accurate transducers, energy consumption data can only be of limited use. Developed especially for precise measurements on rolling stock, the EN-50463-compliant current and voltage sensors from Knick’s ProLine P 50000 series provide the basis for accurate power consumption accounting. The devices are used in protection and monitoring equipment, traction inverters, and auxiliary converters. In addition to current and voltage measurement, they are also used to detect short circuits. The 3-port isolation that is characteristic for Knick transducers completely rules out measuring errors that might otherwise occur due to a galvanic connection of output signal and auxiliary power supply. Moreover, the devices continuously monitor themselves, indicating their status via a diagnostic output. All P 50000 units can be integrated into existing system environments without additional effort, since they transmit measured values as floating analog 0/4…20 mA or 0…10 V standard signals. Maximum flexibility and safety are ensured by the integrated power supply for all voltages typical for the rail sector and by a comprehensive touch protection, which includes the input terminals. This ProLine transducer range comprises special-feature models such as the P 51000 current transducer that provides overload-proof detection of currents in the kA range via a shunt resistor. With this device, not even strong electromagnetic fields influence the measurement result. For precise detection of nominal voltages commonly used in rail applications (750, 1500, 3000 V DC), the ProLine P 50000 series also offers the very compact P 52000 transducer that is notable for safe encapsulation of high-voltage contacts and connections. This ensures there will be no dangerous mutual interference around other components. This transducer can therefore be installed without observing specific safety distances. The ProLine P 50000 range devices meet all normative requirements for use on rolling stock and in traction power substations according to EN 50155, EN 50124, and EN 50123-1. They feature EMC according to EN 50121-1 and EN 501-3-2 and fire protection up to hazard level HL3 according to EN 45545-2 (2016). The devices resist vibration and shock according to EN 61373. They are temperature classified as TX (-40 °C…85 °C) according to EN 50155/EN 50121-1, and altitude classified as AX according to EN 50155. They provide protective separation through reinforced insulation up to pollution degree 3 and over-voltage category 3. They feature protective covers that comply with EN 50153. P 50000 transducers achieve an MTBF (mean time between failures) of 155 years. Knick provides a five-year warranty on the devices.

New voltage presence detector for traction substations and rolling stock

In the rail sector, reliable detection of applied voltages or unwanted potential differences is essential to ensure human safety and the protection of electrical installations. On the one hand, different ground potentials can cause dangerous voltages between wagons and platforms.

full text

In the rail sector, reliable detection of applied voltages or unwanted potential differences is essential to ensure human safety and the protection of electrical installations. On the one hand, different ground potentials can cause dangerous voltages between wagons and platforms. On the other, many switches and electric/electronic components must not be switched under load. Knick Elektronische Messgeräte has developed the ProLine P 52000 VPD voltage presence detector for the safe detection of voltages up to 4200 V in traction substations and on rolling stock. P 52000 VPD is based on the P 50000 transducer series, which complies with all relevant railway standards. A rotary switch installed on the front enables selection of ten predefined thresholds or user-defined values. The voltage detector compares the input signal with the selected threshold value. If, irrespective of positive or negative polarity, the threshold is breached, the detector will open a solid-state switch to signal an applied dangerous voltage. The output is isolated, protected against polarity reversal, and short-circuit-proof up to 30 V DC. The signal level is based on type 1 PLC signal inputs according to EN 61131-2 and is suitable to trigger controllers, hardware relays, and protection devices. Just like all P 50000 transducers, the P 52000 VPD voltage detector features calibrated range selection, 3-port isolation, full touch protection, and an integrated broad-range power supply for all voltages typical for the rail sector. It thus sets a new standard for this class of equipment. The voltage detector is compliant with current railway standards and meets all requirements on fire protection (HL3 according to EN 45545-2 [2016]), electrical safety, mechanical robustness, resilience to extreme climatic conditions, and low EMI susceptibility.

Smooth-running services as well as passenger and employee safety in railway operations depend on functions such as emergency shutdown in the event of short circuits, detection of delayed potentials, and safe signal transmission. Therefore, transducers for railway applications must meet the highest standards of reliability and precision. For Knick Elektronische Messgeräte, this has been the cornerstone in the development and manufacturing of highly available transducers and signal conditioners over several decades. The instrumentation manufacturer based in Berlin, Germany, has been supplying the international railway industry with products for high-voltage applications for over 40 years. At the 2018 InnoTrans exhibition in Berlin, Knick will showcase its proven transducers for traction power substations as well as new products for use on rolling stock: the SIL-2-compliant P16000 pulse frequency conditioner converts pulse signals from speed encoders into galvanically isolated analog 0/4…20 mA or 0…10 V standard signals required by control systems and subsystems to detect the travel speed. The transducer’s signal input is designed according to the SIL 2 safety integrity level to ensure that there can be no inadvertent impact on the signal source. The ability to separate the encoder signal and make it available for other applications eliminates the need to install additional encoders on vehicle axles. Another highlight is the new ProLine P 50000 transducer series for high-precision energy measurement according to EN 50463. This series enables current and voltage measurement in traction inverters and auxiliary converters, and short-circuit detection in protective devices. These are the only devices in their class featuring calibrated range selection, which enables high flexibility in selecting input voltages in the ±4200 V range or currents in the kA range. After range selection, the transducers meet the high specified accuracy without renewed calibration. As the latest addition to the P 50000 series, Knick will present the P 52000 VPD voltage detector for reliable detection of voltages up to 4200 V. The detector compares the input signal with a selected threshold value that can be set at the unit. If, irrespective of positive or negative polarity, the threshold is breached, the detector displays an optical alert and generates an output signal that can activate or control hardware relays, protective devices, or controllers. The signal level is matched to type 1 PLC signal inputs according to EN 6131-2. All products are fully compliant with applicable railway standards and comply with demanding requirements regarding fire protection (HL3 according to EN 45545-2 [2016]), electrical safety, mechanical robustness, high resilience to extreme climatic conditions and low EMI susceptibility.

Knick Elektronische Messgeräte has expanded its range of compact transmitters for the Memosens standard by adding MemoTrans, an extremely lean 2-wire multiparameter solution that supports 4 – 20 mA and HART communication. The combination of transmitter and sensor interface in a single space-saving unit enables a direct, loop-powered connection of the measuring point to the process control system. Thereby, Memosens technology can now also be employed in applications where conventional 2-wire transmitters do not require displays or control units on location, or where there is not enough space for a conventional transmitter. While sensor devices with an integrated transmitter unit have been available on the market for several years now, such combinations meant that the transmitter had to discarded along with the sensor whenever it had to be replaced – and all internally stored configuration and calibration data was lost in that process. The replacement device inevitably required a new configuration, with the associated maintenance and operating expenses. MemoTrans eliminates these drawbacks since the compact transmitter features an inductive sensor connection that can be disconnected. Furthermore, MemoTrans is a multiparameter transmitter. It can be used with all Memosens sensors for measuring pH/ORP, oxygen (amperometric measurement), or conductivity. A red or green LED on the MemoTrans housing indicates whether it is connected to the sensor. Once successfully connected, the Memosens sensor can be automatically identified by its sensor ID. Featuring an integrated Bluetooth interface, MemoTrans provides technical personnel with flexible and convenient direct access to the measuring point without necessarily requiring a display unit. All MemoTrans devices are visualized in the MemoTrans app for iOS and Android smartphones or tablets. Users can thereby set up the transmitter and calibrate and configure the sensor on the spot. The app also displays all current sensor and diagnostic data. In addition, MemoTrans supports the HART fieldbus standard and can therefore be accessed from the control system or via a HART handheld.

Knick Elektronische Messgeräte expand their slim Memosens transmitter series MemoRail for control cabinet installation with a Modbus interface version: The MemoRail Modbus A1405N is the first multi-parameter analyzer that provides process technology operators with an economic, compact transmitter for full-featured integration of Memosens monitoring stations into the fieldbus standard. Up until now, operators could only choose between comprehensively equipped analyzers with a display or compact transmitters with limited functionality. The new MemoRail Modbus modules from Knick, which feature a modular housing with a width of just 17.5 mm, not only transmit all sensor data and readings to the Modbus master using the MODBUS RTU data format. Unlike conventional compact solutions, they also enable unrestricted access to device configuration and sensor calibration via Modbus. Up to 32 transmitters can be connected to a Modbus master. For the measurement of pH/ORP, conductivity or oxygen, MemoRail Modbus can be combined with all Memosens and digital sensors, whether pH glass, IsFET, oxygen, or conductivity (conductive and inductive). What’s more, the DIN rail module is the only analyzer of its class that enables the connection of LDO sensors (luminescent dissolved oxygen) for the optical measurement of oxygen. The new devices come as single- or dual-channel versions with freely combinable parameters or sensors. Either two freely selectable Memosens sensors or a Memosens sensor and a SE 740 LDO can be connected. Additionally, the transmitters allow for the connection of the new SE 554 X/1-AMSN and SE 555 X/1-AMSN combination sensors that synchronously measure pH and ORP values. In this way, a dual-channel MemoRail model provides four readings as well as temperature. The network address for rapid MODBUS configuration is set via DIP switches on the front panel. The 24 V DC supply can be connected either via TBUS or via a cable connected to the terminals at the back. Red and green LEDs indicate the device status, communication interruptions, defective sensors or device settings unsuitable to the sensor as well as the device’s maintenance requirements. Knick provides a 3-year warranty on the MemoRail Modbus transmitters.
