A pressure chamber will be separated by a thin diaphragm. This diaphragm is under static pressure from both chambers and additionally from one chamber with the measuring pressure. The diaphragm will transmit the pressure difference through a bellow and connecting rod onto the movement. The movement indicates the positive or negative value on a dial with 270° angle. A bellow on the opposite side compensates the power. DP Gauges are available from 0-100 to 0-600 mbar to 0-1 to 0-25 bar with cases in 100 mm and 160 mm.
The DP Gauge is available with different connections, swivel adapters, manifolds, chemical seals, DP cells with up to 250 bar static pressure, special dials and electrical contacts.
