The Static“O”Ring type pressure switch with optional wetted

parts is suitable for a wide variety of process applications.

This type is not recommended for high-pressure fluid power

applications where high shock pressure and high cycle rates

are expected. Use the SOR Pivot Seal type (prefaced by 2 or 3)

for fluid power applications.

The pressure sensing element of the Static“O”Ring type

pressure switch is a force-balanced, piston-actuated assembly

sealed by a flexible diaphragm and o-ring. Media pressure

on the area of the piston counteracts the force of the range

spring, adjustable by the adjusting screw, which moves the

piston shaft only a few thousandths of an inch to directly

actuate the electrical snap-action switching element. This

principle of operation virtually eliminates friction and resultant wear.

Pivot Seal Type (prefaced by 2 or 3)

The Pivot Seal type pressure switch is generally suitable for fluid power hydraulic

applications where high shock pressures and high cycle rates are expected and where

only normally industrial clean hydraulic fluid is used. Use Static“O”Ring type for other

process applications.

The pressure sensing element of the Pivot Seal type pressure switch is a force-balanced,

piston-actuated assembly sealed by an o-ring. The piston reciprocates a maximum of

.020 inches. This results in minimal o-ring wear. Media pressure on the area of the piston

counteracts the force of a range spring, adjustable by the adjusting screw, which moves the

piston shaft and the force transmitter to directly actuate the electrical snap-action switching

element. This principle of operation greatly reduces the friction and resultant wear normally

associated with piston-type pressure switches.
