In order to enhance the energy efficiency of buildings, infrastructure and industrial facilities, getting a transparent record of energy consumption is absolutely vital. However, densely packed equipment and distributed installations often complicate the integration of efficient measurement technology. Measurement specialist Gossen Metrawatt therefore now introduces ENERGYSENS, a new modular sensor system for precise energy consumption metering in accordance with precision class 1 in the DIN EN 60688 or DIN EN 62053-21 standards. The new measuring system comprises the slim ENERGY EScom basic module, which is only 2 HP wide, and up to 10 highly compact ENERGY ES sensor units that are available in four versions with 3 or 12 measuring inputs for current ratings of up to 40 A or 80 A. This allows for a flexible connection of up to 120 measuring points with a connection length up to 5 m to each base module. This very versatile solution is also very suitable for tight installation spaces in existing energy distribution boxes. Mounting the devices is very easy. In 50/60 Hz AC low-voltage systems, they can monitor the actual consumption values for effective power, energy, current, voltage and frequency. Moreover, by monitoring the phase load, ENERGYSENS also contributes to preventive maintenance and keeping downtime to a minimum. The sensors feature an extremely low profile with a very slim 13 mm. They are mounted onto the fuses. Measured values are transmitted to the base module via plug-on ribbon cable. Universal Modbus TCP and MODBUS RTU interfaces ensure fast data transfer in a variety of system environments. For an easy system integration without any programming, Gossen Metrawatt provides a free configuration software that is available for download on the company’s website. In addition to the sleek design, ENERGYSENS also excels in term of minimal power consumption, in contrast to much more power-hungry other products on the market.

Measuring technology for testing the electrical safety in sterile or hygienically sensitive areas – ranging from hospitals, laboratories, or medical practices to production facilities in the pharmaceutical or food sector – are subject to particularly strict regulations. For such environments, measuring technology expert Gossen Metrawatt has developed SECULIFE HIT AM, a digital TRMS multimeter featuring an anti-microbial design. The ergonomically designed hand-held device enables TRMS AC and AC + DC measurements, irrespective of the signal shape, for voltages and currents up to 20 kHz. 23 multimeter functions provide secure and reliable measurements for all required inspection tasks, including current measurement from 100 mA up to 10 A, voltage, capacitance and resistance measurement, and diode and continuity tests. In addition, a 1 kHz low pass filter can be switched on to measure e.g. the motor voltage at electronic frequency converters. Measurement of 5 V square wave signals is also supported. For enhanced safety, the housing, cables, and measuring probes are made from an anti-microbial material composition that counteracts microbial colonization. The multimeter comes with IP65 ingress protection. It features an illuminated display with digital and analog measurement indicators, which show fixed values as well as dynamic measurement curves with great accuracy. Measured parameters can be adjusted via a rotary switch and a function key. The measuring range automatically adapts to the reading, but can also be manually selected whenever necessary. A single connection port is used for all current measuring ranges, which completely eliminates any potential confusion. Up to 40 values per second can be automatically stored. The total storage capacity is sufficient for more than 15,000 measurements. The device is approved for CAT IV measurements up to 600V and is extremely safe to operate: in addition to a high-voltage sensor that ensures the input signal is safe to touch, the device features automatic socket blocking, which prevents the incorrect connection of cables or selection of the wrong measured parameters.

Gossen Metrawatt now provide their compact, high-performance ENERGYMID energy meters in two versions designed for direct connection. These models require no external current and voltage transformers, which saves installation space as well as expenses. The recently launched EM 2281 meter measures energy consumption directly in 2-wire AC systems with 230 V voltage. The second model now introduced by the measuring technology experts, the EM 2289 meter has been designed for 4-wire three-phase current with ratings up to 80 A and an input voltage of 400 V. Like all devices in this new generation meter range, the two direct measuring models are pre-calibrated according to MID standards and generate power consumption records and power feed data for differentiated cost accounting. With an extensive range of functions comprising not only energy consumption, but also up to 33 additional parameters depending on the selected model, the EM 2281 and EM 2289 meters are uniquely positioned in their market segment. For instance, they can be used to measure reactive energy, apparent power, neutral conductor current, power factor, frequency and power supply, and will additionally monitor power quality through Total Harmonic Distortion (THD). Users can choose from a range of standard or freely programmable outputs to measure value transmission via pulse. The manufacturer also offers optional interfaces for M-Bus, LON, BACnet, and MODBUS RTU/TCP to facilitate flexible network integration and remote readout.
