  • Mô tả sản phẩm

INFICON VSA100A

“Setpoint 3 mbar below ambient “

The INFICON Vacuum Switch VSA100A is used as a safety switch in vacuum systems. For example, to automatically interrupt the gas supply when venting vacuum systems with a purge gas at a pressure of 6 mbar below atmospheric pressure.

At a differential pressure of 6 mbar resp. return switching pressure of 3 mbar below atmospheric pressure, an elastic diaphragm actuates a changeover contact which in turn may be used to switch directly any ancillary equipment.

Advantages

  • Reliable and budget-priced vacuum switch
  • High life time
  • Rugged design
  • Easy to integrate
  • IP 44 protection

Typical applications

  • Control of load lock chambers
  • Safety shutdown of vacuum systems

Specifications

Switching pressurembar6 ±2 (below atmosphere)
Back switchingmbar3 ±2 (below atmosphere)
Operating pressure (absolute)bar<2
Protective typeIP 44
Materials exposed to vacuumstainless steel 1.4305, EPDM, PTFE (Teflon)
Technical Note: Due to the diaphragm material used (EPDM) the Vacuum Switch VSA100A is not suited for applications in which the process gascontains large quantities of helium. The leak rate of the diaphragm for helium is  5 x 10-5 mbar l/s.
