CS106 Barometric Pressure Sensor
7. Installation
7.1 Jumper Settings
The CS106 can be operated in one of two modes: shutdown and normal. The
mode is selected by a jumper located underneath the plastic cover of the
barometer. When the jumper is not installed, the CS106 is in shutdown mode
and the datalogger turns the CS106 on and off with a control port or excitation
channel; to use the excitation channel, the datalogger must be able to provide
an excitation voltage of 5 Vdc. When the jumper is installed, the CS106 is in
normal mode and powered continuously.
CS106s shipped from Campbell Scientific are configured for
shutdown mode (jumper open).
The location of the jumper is shown in FIGURE 7-1.

7.2 Mounting in the Enclosure
To prevent condensation, install the sensor in an environmentally protected
enclosure, complete with desiccant, which should be changed at regular
intervals.
Failure to protect the sensor from condensation may result
in permanent damage.
The CS106 is typically mounted in a Campbell Scientific enclosure next to the
datalogger. Campbell Scientific also offers the ENC100 for situations where it
is desirable to house the CS106 in its own enclosure (see FIGURE 7-2). The
ENC100 is a 6.7-in. x 5.5-in. x 3.7-in. enclosure that includes a compression
fitting for cable entry, a vent for equalization with the atmosphere, a backplate
