Capsule vacuum gauges

This movement is transmitted fo a point by a lever system. The capsule vacuum gauge, designed according to this principle, indicates the pressure on a linear scale, independent of the external atmospheric pressure. [Pg.77]

Capsule vacuum gauges measure pressure accurately to 10 mbar (due to the linear scale, they are least accurate at the low pressure end of the scale). If only pressures below 30 mbar are to be measured, the DIAVAC is... [Pg.78]

The best-known design of a diaphragm vacuum gauge is a barometer with an aneroid capsule as the measuring system. It contains a hermetically sealed, evacuated, thin-walled diaphragm capsule made of a copper-beryllium alloy. As the pressure drops, the capsule diaphragm expands. [Pg.77]

The mechanical phenomena gauges measure the actual force exerted by the gas. They include a U-tube, a capsule dial, a strain, a capacitance manometer, a McLeod gauge, etc. Vacuum is measured according to the displacement of an elastic material or by measuring the force required to compensate its displacement. The measurement ranges from atmospheric pressure to 102 Pa in rough vacuum conditions. [Pg.51]
