DESCRIPTION

The use of VC2 type single crystal material in the CP

104 compression mode dynamic pressure transducer

provides an extremely stable instrument.

The transducer is designed for long-term monitoring

or development testing.

The CP 104 pressure transducer may be operated with

either softline or hardline cables depending on the required temperature.
