VRC Electronic Vacuum Switch

Product Announcement from Thyracont Vacuum Instruments GmbH

VRC Electronic Vacuum Switch-Image

Absolute Pressure 1200 to 5 mbar (=hPa), 900 Torr to 1 Torr

The VRC electronic vacuum switch can be used for directly switching a pump or valve in the rough vacuum range. An additional recorder output allows a continuous monitoring of the process pressure.


  • Chemically resistant ceramic sensor with Viton® sealing (Kalrez® sealing on request)
  • Dry relay switch point (switch-over relay)
  • High reliability
  • Excellent reproducibility
  • After detaching the top the switch point is easily adjustable over the whole range by means of a potentiometer
  • Connection by KF small flange or G1/4 female thread
  • Robust metal housing with IP54 protection class

Typical Applications

  • Process automation
  • Plant construction
  • Control of vacuum appliances
  • Operational control of vacuum pumps and plants
  • Additional pump switching
  • Pressure control in the rough vacuum range, e. g. for vacuum furnaces or control and regulation boards
