The SOR weatherproof pressure/vacuum/compound pressure detector is one of our most popular instruments. Models with standard wetted parts are normally ideal for air, oil, and non-corrosive process applications however; we can build one to handle corrosive requirements.
At the heart of this mighty SOR pressure detector is a force-balanced, piston-actuated assembly with the sensing element sealed by a flexible diaphragm and a static O-ring. A wide variety of wetted parts are available and a metal diaphragm can be welded to the pressure port thereby eliminating the O-ring.
- Low-cost general-purpose workhorse
- “Set it and forget it” dependability
- Ranges from 30 in Hg vacuum to 7000 psi
- Set point adjustable with calibrated scale
