Head Mount Transmitter

SITRANS TH100 two-wire Temperature transmitter for PT100 RTD’s. TH100 dispenses with electrical isolation and universal sensor connection to provide a low-cost alternative for PT100 measurements. Due to Its compact size it can be installed in the connection head type B(DIN 43729) or larger. The output signal is 4 to 20 mA that is proportional to the temperature. TH100 transmitter comes without both electrical isolation and explosion protection.
