CS106 Barometric Pressure Sensor

FIGURE 3-4. ENC100 is a very small enclosure that can house

one CS106.

Remember that for the sensor to detect the external ambient pressure, the

enclosure must vent to the atmosphere (i.e., not be ‘hermetically sealed’).

Enclosures purchased from Campbell Scientific properly vent to the

atmosphere.

For user-supplied enclosures, it may be necessary to make a vent

hole on the outer wall. In this situation, do not make the hole on

one of the vertical side walls, as wind blowing around it can

cause transient changes in pressure.

NOTE

The mounting holes for the sensor are one-inch-centered (three inches apart),

and will mount directly onto the holes on the backplate of 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.
