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;
