Dwyer WHT-32A Weather-Resistant Humidity/Temperature Transmitter is a reliable and accurate device for monitoring humidity and temperature levels. With a drift of less than 1% RH per year and a wide temperature range of -40 to 140°F, it provides precise measurements. The transmitter features a 4-20 mA output with an accuracy of ±0.9°F @ 72°F and a passive output with an accuracy of ±0.36°F @ 77°F. It operates on 10-35 VDC power and has a fast response time of 15 s. The transmitter is housed in an ABS enclosure with an enclosure rating of NEMA 3S (IP54). It uses a capacitance polymer sensor with a humidity range of 0 to 100% RH and has a removable screw terminal block for easy electrical connections. The output signal varies depending on the model, with the 4-20 mA loop powered models providing a 4-20 mA signal, the 0-10 V output models offering 0-10 V @ 5 mA max, and the 0-5 V output models delivering 0-5 V @ 5 mA max. It can also operate within a storage temperature range of -40 to 176°F and has a repeatability of ±0.1%. The Dwyer WHT-32A is an ideal choice for applications that require reliable and accurate humidity and temperature monitoring.
