VRC – Electronic Vacuum Switch

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.

Benefits

• 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
