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.
