Industrial Integrated Head Mounted Temperature Transmitter With Hart Protocol
WNK65 4~20mA two-wire integrated circuit board is specifically designed for intelligent temperature transmitters. The compact head mounted transmitter type 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.
