Universal Input Smart Temperature Transmitter 4~20mA Hart Output
With Explosion Proof
WNK6T smart temperature transmitter is high performance product
from WNK. It is universal input temperature transmitter, with
output choices of 4~20mA, 4~20mA+Hart, Modbus or Profibus-Pa.
Every transmitter is ambient temperature compensated before shipped
out, to ensure transmitters high accuracy, minimum drift in wide
working temperature range and good long-term stablity.
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:
1. 4~20mA, 4~20mA with Hart or Profibus PA outputs are available
2. High accuracy: ±0.1℃ for RTD; ±1℃ for TC, code end accuracy ±2℃
3. Good long-term drift<0.1/year
4. LCD display, Menu-guided operation.
5. Install easily, more flexiable
6. To reduce the overall cost of installation,maintenance and
running.
