4~20mA Hart Smart Temperature Transmitter with Explosion Proof and High Accuracy 0.1 Deg C
WNK6T smart temperature transmitter is high performance product from WNK. It is universal input temperature transmitter, translating signal of thermal resistor,resistive transducer, thermocouple or voltage sensor into standard signal.
Transmitters adopt specific integrated circuit digital technology to achieve the best consistency of accuracy and signal. Every transmitter has been done with ambient temperature compensation before shipped out, to ensure transmitters highest accuracy and mini drift in wide working temperature range.
Our transmitters are easy for on-site installation, they can be integratively installed with temperature sensor, or installed away from sensor. The solid housing is with global universal wire connector, and the aluminum shell of double chamber structure ensures regular work of the transmitter in dangerous occasions.
