HWgroup – Sensor 0-20mA 1W-UNI


SKU: 600566 Category:

0 to 20mA DC current sensor – converter for the 1-Wire UNI (RJ11) bus. Electrically isolated, measures externally sourced current. Compatible with Ares, Poseidon2 and more. Warranty: 24 months

Isolated DC current sensor for the 1Wire-UNI bus. Sensor for measuring currents in the 0–20mA range. It is typically used to connect a industrial probe with 4–20mA output – 4wire with discrete power supply (e.g. to measure the fuel level in a tank). Sensor current output is processed in Poseidon2 or Ares units to be accessible via LAN or GSM.

Sensor is equipped with 8-points calibrating table/curve to set measured output appropriate to related industrial sensor. The calibration process is supported by  1W-UNI USB calibrator. USB dongle.

For two-wire industrial sensors 4-20mA use  alternative Sensor 4-20mA 1W-UNI,

  • Input: 0-20mA (connect a “source” type of probe).
