WNK65 Temperature Transmitter
WNK65 is suitable for four types of thermal resistors including Cu50, Cu100, PT100, PT1000 and eight types of thermocouple including E, J, B, K, N, R, S, T type. And it supports measurement of minivolt signal of -10~100mV and -100~1000mV, and resistive signal of 0~400Ω and 0~4000Ω. Isolation voltage is DC1000V.
Pls read the instruction carefully before using WNK65, and operate accordingly. If there is anything unclear in application, pls do not heisitate to contact us, we will come to you and solve problems as soon as possible.
WNK65 Temperature Transmitter

5. Internal code end compensation accuracy: ±0.5ºC
6. Damp: 0-64 seconds adjustable;
7. Data refreshing frequency: 4times/second;
8. Stability: ±0.2%/year;
9. Woring ambient temperature range: -40ºC~+85ºC;
10. Dimensions: φ44mm;
11. Mounting hole distance: 33mm;
12. Anti mechanical vibration: 10~60HZ,0.21mm sine wave;
13. Anti radio frequency interference: IEC61000-4-3, 20V/M,80~1000MHZ
2. Hardware components
2.1 Power
- Supplying power range is DC9V~32V, connected from port 1 and 2.
- Inlay opposite direction voltage protection circuit, misconnetion of power will cause no damage.
Note: Never connect 24V with sensor port! It will cause permanent damage of transmitter!
