KM Temperature Transmitter

Brand: KOBOLD Instruments, Inc.

Transmitters for head mounting model KM, transform resistance values or thermal voltage into a standard current signal 4 to 20 mA. Transmission is absolute interference-free over long distances.

Different sensor inputs are Resistance thermometers, Thermocouples, Resistance and Voltage. Programming of measuring ranges is via U-pro and HART® protocol. Connection head for mounting these U-pro transmitters is according to DIN 43 729 form B.
