The Murphy 0-5000 PSI Explosion Proof Pressure Swichgage Instrument with Stainless Steel Bourdon Tube/Socket 45APE-S-5000-EX is a mechanical gage for pressure indication. It includes 2 adjustable SPDT switches. These snap-acting switches can be used for start and stop, to trip alarms and to shut down equipment. This swichgage instrument is a surface mount (square case) type with stainless steel bourdon tube sensing element. The 45APE Series models are widely used in applications requiring pressure indication and Form “C” low and high pressure switches.

The 45APE Series utilizes a bourdon tube sensing unit with a stainless steel dual-sector geared movement. Each of the sectors drive separate pointers when pressure is applied to the bourdon tube. The indicating pointer (visible pointer) shows actual pressure reading, including below and beyond the low and high trip points. The low and high trip points are adjustable independently on the gage front lens. The switch operator pointer (behind the dial) is calibrated to follow the indicating pointer. The low and high trip point indicators “arrest” the switch operator pointer, and as pressure decreases or increases, through “the principal of lost motion” the respective snapswitch is tripped.
