VRC Electronic Vacuum Switch ● Piezo ● 1200 to 5 mbar

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.

描述

  • Chemically resistant ceramic sensor with FKM sealing (FFKM 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

应用

  • 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
