Download Datasheet



The WDT-DW wet and dry bulb humidity tank would normally be wired to a IN-HWD (rev 2) Humidity and Temperature Indicator/Transmitter (or similar) with two 4~20mA outputs representing 0~100% RH plus 0~100degC. Because the WDT-DW is made to the DIN standard with Band 5 Pt100 sensors, the accuracy of the system is more reliant on the wet and dry bulb transmitter.
