Absolute Pressure Switch E48W Series

The E48W series absolute high purity pressure switches offer accurate, repeatable switching for monitor/control and alarm/shut down protection.  Specifically designed for high purity gas systems, and to operate at pressure points referenced to absolute zero. These products should be specified when changes in atmospheric pressure would have an adverse effect on switch operation or when hermetically sealed contacts are required.
