Product Description
Vacuum Switch Gauge
Fischer offers MS10 Series pressure gauge + switch for Overpressure and vacuum measurement and control.
Application
Overpressure and vacuum proof contact pressure gauge for control and supervising purposes in vacuum processes.
Construction and Operation
The measuring system consists of two encapsulated and hydraulically coupled metal diaphragm. When subjected to pressure it causes a deflection proportional to the strength of pressure. Opposite of the medium-touched diaphragm a tappet returns the deflection to a motion work and the operating elements of the micro switches.
When subjected to excessive pressure each metal diaphragm based oneself on the chassis of the capsule. Therefore the device is prevented from damage.
