Head Mounted Temperature Transmitters

The compact head mounted transmitter type from ABB is designed for standard type B sensor heads. The advantage increased measuring accuracy resulting from conversion of the sensor signal into a stable output signal close to the sensor. For thermocouple applications without compensation cables.
