Sensor 4-20mA 1W-UNI

Isolated DC current sensor for the 1Wire-UNI bus. Sensor for measuring currents in the 4–20mA range. It is typically used to connect a industrial probe with 4–20mA output -  2wire current loop ("sink"type). The sensor's current output is processed in Poseidon2 or Ares units to be accesible via LAN or GSM.
The sensor is equipped with 8-points calibrating table/curve to set the measured output appropriate to the related industrial sensor. The calibration process is supported by 1W-UNI USB calibrator (USB dongle).
