Electronic Vacuum Switch Absolute Pressure 1200 to 5 mbar The VRC electronic vacuum switch can be used as a security switch or for directly switching a pump or valve in the rough vacuum range. An additional recorder output allows a continuous monitoring of the process. The IP54 category housing ensures protection in rough environmental conditions. Typical Applications • Control of vacuum appliances • Chemically resistant ceramic sensor with FKM sealing, FFKM sealing on request • Operational control of vacuum pumps and plants • Security switching • Dry relay switch point (switch-over relay) • Additional pump switching • High reliability • Pressure control in the rough vacuum range, e. g. for vacuum furnaces or control and regulation boards • Excellent reproducibility • Process engineering • Plant construction • After detaching the top the switch point is exactly adjustable over the whole range by means of a potentiometer • Connection to vacuum source by KF small flange or G1/4 female thread • Robust metal housing w
