Pivot Seal Pressure Switch
Brand: SOR Inc
SOR Pivot Seal pressure switches are rugged, field-mounted instruments that incorporate a flexible modular design.
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.
