CPB 5000 DP
WIKA Operating Instructions Differential Pressure Balance Version 1.0 3
1. Arrangement of control elements .
2. General description .
The instrument includes two common pressure-balances of the basic series CPB5000.
For the calibration of differential gauges at a static line pressure, the systems can be seperated.
One system is used to generate the line pressure. The second one supplys the differential pressure
(including line pressure). Following the description for the use of the instrument.
