High Accuracy Industrial IP67 Universal Input Smart Temperature Transmitter With 4~20mA, Hart, Profibus-PA


WNK6T smart temperature transmitter is high performance product from WNK. It supporsts outputs of 4~20mA, 4~20mA+Hart, Profibus-Pa or Modbus with universal input of  RTD, TC, MV, ohms.


Transmitters adopt specific integrated circuit digital technology to achieve the best consistency of accuracy and signal. Every transmitter is ambient temperature compensated before shipping out, to ensure transmitters high accuracy of 0.1 Deg C and good long-term stability. 


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.



Quick Information:


  • Digital accuracy:±0.01℃, Pt100 thermal resistor input;
  • Accuracy: ±0.1℃ for RTD; ±1℃ for TC, code end accuracy ±2℃;
  • Optional 4~20mA, Hart, Profibus-Pa protocols;
  • Universal sensor inputs(RTD, TC, mv, ohms);
  • Support GSD file;
  • 24 bit analog -digital converter with ambient temperature compensation, the measurement performance is outstanding in the whole working range;
  • Self-calibration: by comparing the dynamic measurement with the very stable and accurate internal reference, the AD converter circuit automatically makes self-calibration for each update temperature;
  • Double chamber shells, ensuring transmitter excellent reliability in high temperature, corrosive and radio frequency interference;
  • Integrated transient protector, preventing temperature transmitter from damage caused by transient current of a circuit;
