CS115 Barometric Pressure Sensor

3.Installation

3.1Venting and Condensation

CAUTION

NOTE

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.
