The 1-Wire UNI 0-20mA Current Sensor is an isolated DC current sensor with a 1Wire-UNI bus that can measure currents from 0-20mA. The sensor is typically used with an industrial probe with 4–20mA output 4-wire and a discrete power supply to measure fuel in a storage tank. The sensor has an 8-point calibration table and can be calibrated using a 1W-UNI USB calibrator dongle. The sensor is designed for use with ARES, Poseidon2 and SD-2×1Wire environment monitors.
