The iTEMP TMT80 head transmitter can be installed in the form B sensor head. It has a 4 to 20 mA analog output.
The measuring range can be set up freely via ReadWin® 2000 configuration software. TMT80 can be used for resistance thermometers (RTD) as well as for most commonly used thermocouples.
The iTEMP TMT80 head transmitter converts the input signal into a linear 4 to 20 mA signal. It has measurement input for resistance thermometers (RTD) in 2-, 3- or 4-wire connection and thermocouples.
