Series PG Gas Pressure/Differential Pressure Switch

External Adjustment, Visible Dial, Hermetically Sealed Snap or Mercury Switch

Large sensitive diaphragm and reliable, time proven mechanical design are combined in Series PG Gas Pressure/Differential Pressure Switches. For use with air and other compatible gases, they feature excellent ±1% of full scale repeatability, clear easy-to-read scale and convenient external setpoint adjustment.

Application flexibility is assured by a large variety of switching options including SPST, SPDT, DPST and DPDT; opening or closing on increasing pressure, vacuum or differential. PR and PRL models add manual reset operation on increasing or decreasing pressure. Mercury switches or hermetically sealed snap switches are available where high humidity would be a problem. If vibration or other factors preclude the use of mercury, snap switches can be provided. Standard housing is NEMA 1. Optional enclosures can be supplied for weather resistant requirements.
