The Murphy Explosion-Proof 0-400 PSI Surface Mount Swichgage Instrument with Square Case 45APE-S-400-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. 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 snap-switch is tripped. The 45APE Series models are widely used in applications requiring pressure indication and Form “C” low and high pressure switches.
