WHT-330 WHT-333 WHT-31A WHT-32A 美***Dwyer德威尔 温湿度变送器

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.
