VSC150A abs. switch, passiv

The INFICON Vacuum Switch VSC150 is a absolute pressure switch with a adjustable electrical switching contact from 0.5 to 2000 mbar. The mechanical design allows a short therm overload of 3000 mbar without any impairing the switching accuracy of ± 0.1 mbar. INFICON offers customer specific adjustment of pressure switch.

Benefits

  • High switching accuracy (± 0.1 mbar)
  • Stable long term operating characteristics
  • Rugged, corrosion protected design

Features

  • Switching contacts (normally closed) in the reference chamber and thus protected against process media
  • Increased switching capability when using switching amplifier
  • Adapter available for differential pressure measurement

Typical Applications

  • Pressure switch or differential pressure switch to control valves, pumps, power supplies
  • Load lock chambers
  • Process chambers
