EW Series Absolute Pressure Switch?

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.
- E17W Series Absolute Pressure Switch
- E36W Series Absolute Pressure Switch
- E48W Series Absolute Pressure Switch
?
PVW Series Vacuum Pressure Switch?

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).
PW Gauge Pressure Switch?

P-W Gauge Pressure Switch
These units, designed specifically for use with high purity gas applications, are used to measure gauge pressure (above atmosphere).
