CS115 Barometric Pressure Sensor

3. Installation
3.1 Venting and Condensation
To prevent condensation, install the sensor in an environmentally protected
enclosure, complete with desiccant which should be changed at regular
intervals. As the sensor must detect the external ambient pressure the enclosure
must not be ‘hermetically sealed’.
Failure to protect the sensor from condensation may result
in permanent damage.
If it is necessary to make a vent hole on the outer wall of an
enclosure, do not make the hole on one of the vertical side walls,
as wind blowing around it can cause transient changes in
pressure.
3.2 Mounting
The mounting holes for the sensor are one-inch-centered, and will mount
directly onto the holes on the backplates of the Campbell Scientific enclosures.
Mount the sensor with the pneumatic connector pointing vertically downwards
to prevent condensation collecting in the pressure cavity, and also to ensure
that water cannot enter the sensor.
