CS100 Barometric Pressure Sensor

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

7.2 Wiring

7.2.1 Datalogger Connection

Before connecting the barometer to the datalogger, a yellow warning label

must be removed from the pigtails (see FIGURE 7-2). The warning label

reminds the user of the importance of properly connecting the barometer to the

datalogger. Proper wiring is shown in TABLE 7-1.
