Gas Pressure/Differential SPDT Pressure Switch, w/ Snap Switch (1.0" - 30" W.C.)

Gas Pressure/Differential SPDT Pressure Switch, w/ Snap Switch (1.0" - 30" W.C.)

Large sensitive diaphragm and reliable, time proven mechanical design are combined in Series PG Pressure/Differential Pressure Switches. For use with air and other compatible gases, they feature excellent +/-11% of full scale repeatability, clear, easy-to-read scale and convenient external set point 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. 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 switched can be provided. Standard housing is NEMA 1. Optional enclosures can be supplied for weather resistant requirements.
