The VPLog-i measures AC currents up to 3200A (true-rms on a single phase power cable). The VPLog-i is very easy to use: just wrap around one of the three phases and close the snap fitting. It offers the best solution for your mobile power measurements. The VPLog-i is the only sensor on the market that offers both 4..20mA and pulse outputs.
Easy does it: Just open the sensor and wrap around the power cable you want to measure. The LED on the device blinks when the VPLog-i is powered. The rate at which it blinks is proportional to the output current. You can use one of the two outputs to get accurate measurement results.
The current sensor measures the input power of your compressor’s electric motor. When combined with a flow meter, it can be used to determine the actual efficiency of the compressor.
