The explosion proof SOR hermetically sealed pivot seal pressure switch makes sense when plant conditions contain flammable/combustible gases, vapors or dust that dictate UL, CSA or ATEX certifications. (According to the National Electrical Code, the definition of an explosion proof apparatus is a device enclosed in a case that is capable of withstanding a gas or vapor explosion. This means that, should an explosion occur, it will be contained within an enclosure).

The pressure-sensing element of the pivot seal pressure switch is a force-balanced, piston-actuated assembly sealed by an o-ring. As with all SOR pressure switches, the actual travel of the piston to actuate the micro switch is only several thousandths of an inch, resulting in minimal o-ring wear. Media pressure on the area of the piston counteracts the force of the range spring (adjustable by the adjusting nut screw) and moves the piston shaft and the force transmitter to directly actuate the electrical snap-action switching element.
