HW group Temp-1W-Pt100

Double converter to connect two Pt-100 and Pt-1000 probes to 1-Wire UNI (RJ11). One or two external temperature probes can be monitored over LAN (Poseidon2) and GSM (Ares). Typical applications include measuring extreme temperatures in furnaces, coolers, engines, etc.

The converter connects one or two Pt100 or Pt1000 platinum temperature sensors to the 1-Wire UNI bus. Pt100 probes are available in numerous form factors designed for various uses.

The “Converter 2xPt100 1W-UNI” can be connected to Poseidon2 or Ares units. The values can be shared over LAN or GSM.
