Description

The TxIsoBlock in-head temperature transmitter is used to convert thermocouple or PT100 sensor outputs to an isolated industry-standard 2-wire 4-20mA signal. They can be fully configured by the end-user to accept most thermocouple types and PT100 RTD.

Configuration of input type and working range is achieved using the TxConfig adaptor cable and TxConfig Windows software.
