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
