Electrical Current Transmitter to Measure Compressor Energy Consumption
The SUTO S030 current clamp 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 1000 A AC.
The digital converter supplies an output of 4 … 20 mA DC in linear proportion to the measured current. It comes with a wide measuring range and high accuracy.
Single Phase Power Measurements
By measuring the current of a symmetric power consumer on one phase, compressed air experts can calculate the power consumption of the compressors without the need of measuring voltage additionally.
This offers an analysis of the compressor and allows the user to identify the efficiency of the system.
Application
- Current sensing at compressors for load / unload analysis
- Current sensing for power / energy measurement
- Evaluation of machine operation hours
