Water-resistant humidity transmitter with sintered filter | 3% accuracy | 0-5 VDC humidity output.

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.
