Inficon Vacuum Switches are designed for accurate and reliable pressure detection. These robust electronic switches are used in all vacuum applications, including pressure interlock. This VSA 200 switch is an absolute reference vacuum device. For complete use and specifications see .pdf's to the left at Downloads. Key Features: • Corrosion resistant all stainless steel design. • Robust design, cleanroom compliant. • Easy installation with setpoints factory preset or field adjustable. • IP 44 protection. • Atmospheric pressure detection for all vaccum applications. • Pressure interlock (power supplies, gas supplies, pumps, valves, actuators, etc.

INFICON Vacuum Switches are designed for accurate and reliable pressure detection.The pressure switch VSA100A is used as a safety switch in vacuum systems. For example, to automatically interrupt the gas supply when venting vacuum systems with a purge gas at a pressure of 6 mbar below atmospheric pressure. At a differential pressure of 6 mbar resp. return switching pressure of 3 mbar below atmospheric pressure, an elastic diaphragm actuates a changeover contact which in turn may be used to switch directly any ancillary equipment. The electrical connections are protected by a plastic cover.. For complete use and specifications see .pdf's to the left at Downloads.
