Precision Sensors high purity pressure switches offer accurate, repeatable switching for monitor/control and alarm/shut down protection.
In the graph above the abbreviations stand for the following:
PW: P-W Gauge Pressure Switch
PVW: PVW Series Vacuum Pressure Switch
EW: E-W Series Absolute Pressure Switch
The colored arrows show where these products are used in the Semiconductor manufacturing process. Learn more about each of these products in the links below.
E-W Series Absolute Pressure Switch
These products are specifically designed for high purity gas systems, and to operate at pressure points referenced to absolute zero.
PVW Series Vacuum Pressure Switch
These units, designed specifically for high purity gas systems are vented to ambient conditions for sensing pressure below ambient (vacuum).
P-W Gauge Pressure Switch
These units, designed specifically for use with high purity gas applications, are used to measure gauge pressure (above atmosphere).
