Pressure & Vacuum Switch
Brand: SOR Inc
SOR pressure switches are rugged, field-mounted instruments.
The pressure sensing element of the SOR pressure switch is a force-balance, piston-actuated assembly. The sensing element is sealed by a flexible diaphragm and a static O-ring.
A wide selection of wetted parts materials for media compatibility and containment are available.
A metal diaphragm may be welded to the pressure port for certain applications, thereby eliminating the O-ring.
