WHT Weather-Resistant Humidity Transmitter (WHT Weather-Resistant Humidity Transmitt)

wht weather-resistant humidity transmitter (wht weather-resistant humidity transmitt)

wht weather-resistant humidity transmitter

series wht weather-resistant humidity/temperature transmitter

compact housing, sintered filter

the compact series wht humidity/temperature transmitter is designed to withstand the elements. A removable sintered filter protects the polymer capacitance sensor from solid objects that may come in contact with the transmitter. The transmitter is available with 4 to 20 ma or 0 to 10 vdc output signals for both temperature and humidity. This transmitter is ideal for measuring outside air temperature and humidity levels for air handling economizer applications.

product applications

air handling economizers

air environment monitoring in agriculture or livestock cultivation houses
