4-20ma Output Temperature Transmitter Module Head mounted Temperature Transmitter
WNK65 head-mount temperature transmitter is universal input type transmitter. It is suitable for four types
of thermal resistors including PT100, PT1000, Cu50, Cu100, eight types of thermocouple including E, J, B, K, N, R, S, T type,
minivolt signal of -10~100mV and -100~1000mV andresistive signal of 0~400Ω and 0~4000Ω. Isolation voltage is DC1000V.
WNK65 temp transmitter has output of 4~20mA and 4~20mA+Hart. And it
supports software calibration with high cost performance.
