Precision Sensors' high-purity pressure switches are considered "best-of-class" in the semiconductor equipment market. Designed specifically for the demanding requirements of semiconductor tool OEMs, they provide highly repeatable on-off switching for alarm, shutdown and interlock applications. Wetted surfaces are VIM - VAR 316L and are standardly 10 Ra or 5 Ra depending on the requirement. End connections include face-seal, flow-through and flush-type fittings. Set points can be gauge, absolute or vacuum - and cycle life can be over 1 million on-off cycles. Manufacturing of high-purity products is done in a clean-room environment.
The PV36W series vacuum high purity pressure switch offers accurate and repeatable switching for monitor/control and alarm/shut down protection. These units, designed specifically for high purity gas systems, are vented to ambient conditions for sensing pressure below (vacuum) ambient.
