On-site Smart Temperature Transmitter PT100 Thermowell Profibus-Pa Protocol


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


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.



Quick Information:      

  • Digital accuracy:±0.01℃, Pt100 thermal resistor input;
  • Accuracy: ±0.1℃ for RTD; ±1℃ for TC, code end accuracy ±2℃;
  • 4~20mA, Hart, Profibus-Pa protocols for option;
  • 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;
  • Double chamber shell, which makes the transmitter have excellent reliability in high temperature, corrosive and radio frequency interference
  • Integrated transient protector, can prevent the transmitter from the damage caused by transient current of a circuit
  • Self-calibration: by comparing the dynamic measurement with the very stable and accurate internal reference, the analog -digital converter circuit automatically makes self calibration for each update temperature
