Outdoor Humidity Sensor (P/N 203-5761)
CPC specs a outdoor relative humidity (RH) sensor with a 0-5VDC output for use in building
control and anti-sweat control applications using CPC input boards.
Specifications
Sensing Element
Digitally profiled thin-film capacitive
Accuracy
±2% RH over the range 20%-90% RH
Stability
±1%@ 20°C (68°F) annually for 2 years
Operating
0-100% RH
Humidity Range
Choosing a Mounting Location
The outdoor RH sensor should always be mounted on the north side of the building if in the
Northern Hemisphere, or on the south side if in the Southern Hemisphere. The sensor should be
mounted under an overhang or otherwise out of direct sunlight (if possible).
Mounting
1.
Secure the rear side of the enclosure to the outside wall
using the two mounting brackets, as shown in Figure 1.
The tube holding the sensor element should point straight
down.
2.
If you will be running the sensor cable through the wall
behind the sensor, cut or drill a hole in the wall through
the hole in the enclosure.
