Pivot Seal – Weatherproof Pressure Switch

The weatherproof SOR pivot seal pressure switch makes sense when you need protection from the elements but do not require the more expensive explosion proof model.

The pressure sensing element of the pivot seal pressure switch is a force-balance, piston-actuated assembly sealed by an o-ring. As with all SOR pressure switches, the actual motion 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.
