Benefits 2/3 SUTO current sensor is an AC RMS current sensor composed of a flexible active part (Rogowski coil model) connected to a compact digital converter, capable of measuring the current carried on a power conductor up to a value of 3000 A AC. The digital converter supplies an output of 4 ... 20 mA DC in linear proportion to the measured current. S030 Electrical Current Transmitter • Current sensing at compressors for load / unload analysis • Current sensing for power / energy measurement • Evaluation of machine operation hours Current Transmitter Application Conductor Position Typical Error(%) < 0.5 % < 0.8 % < 1 % Easy installation Wide measuring range Accurate current sensing 4 ... 20 mA output signal IP67 casing provides robust protection in the industrial environment Compressor Pitot Tube Flow Meter Filter S551 S030 M oMd bus sensor M 3 A MPa C˚ MPa C˚ 1 C˚ dt A C˚ dt 4 2 Modbus sensor S430 Portable Data Logger Electrical Current Transmitter Position Sensitivity Accurate current measurement By measuring the current of a symmetric power consumer on one phase, compressed air experts are able to calculate the power consumption of the compressors without the need of measuring voltage additionally. This offers an analysis of the compressor and allows to judge the efficiency of the system. Single Phase Power Measurements
