2.3 Physical

Dimensions (Main Box): 9.1 x 6.1 x 2.5 cm (3.6” x 2.4” x 1.0”)

Weight: 135 g (4.8 oz)

Mounting Hole Centres: 7.62 cm (3 inches)

Pressure Connector: 1/8” ID barbed fitting

The black outer jacket of the cable is Santoprene

rubber.

This compound was chosen for its resistance to temperature

extremes, moisture, and UV degradation. However, this jacket

will support combustion in air. It is rated as slow burning

when tested according to U.L. 94 H.B. and will pass

FMVSS302. Local fire codes may preclude its use inside

building.

3. Installation

3.1 Venting and Condensation

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-centred (three inches apart),

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.
