CS450/CS455 Pressure Transducer

The model number and pressure range is etched on the housing. Check this

information against the shipping documentation to ensure that the expected

model number and range were received.

Gauge pressure (Vented) devices must always have a desiccant tube attached.

New desiccant is blue in color. As the desiccant material absorbs water vapor,

it begins to turn pink, and eventually white when fully expired. Desiccant tubes

should be inspected regularly (i.e. every two months) and historical

information will help to baseline desiccant replacement requirements for a

given application/climate.

The desiccant tube is shipped with a black cap to cover the

vent hole. This cap MUST be removed prior to installation.

CAUTION

Remember that although the CS450/CS455 is designed to be a rugged and

reliable device for field use, it is also a highly precise scientific instrument and

should be handled as such. There are no user serviceable parts and any attempt

to disassemble the device will void the warranty.
