Instruction Manual
CS106 Barometric Pressure Sensor 
for mounting the CS106, and hardware for mounting the ENC100 to a tripod, 
tower, or pole. 
FIGURE 7-2. 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. 
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.
