技术说明
The 083E Relative Humidity Sensor measures variance in the capacitance change of a one micron thick dielectric polymer layer. This film absorbs water molecules through a metal electrode, and causes a capacitance change that is proportional to relative humidity. The thin polymer layer reacts quickly, providing up to 90% of the final value of relative humidity in fewer than five seconds. The sensor’s response is essentially linear, with small hysteresis, and negligible temperature dependence.
Temperature is measured with an internal thermistor.

Additional Compatibility Information
Mounting
When exposed to sunlight, the 083E must be housed in a 41003-5 or RAD14 naturally aspirated radiation shield. The 41003-5 and RAD14 attach to a crossarm, mast, or user-supplied pipe with a 2.5 to 5.3 cm (1.0 to 2.1 in.) outer diameter.
The RAD14 uses a double-louvered design that offers improved sensor protection from driving rain, snow, and insect intrusion. A better measurement can be made by providing lower self-heating in bright sunlight combined with higher temperatures (> 24°C [~75°F]) and low wind speeds (< 2 m s-1 [~4.5 mph]).
