Pressure and Vacuum Switches for Process Applications

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

Application Information

The SOR pressure switches in this catalog are suitable for a variety of process applications. Basic models with standard wetted parts are normally suitable for air, oil, water and noncorrosive processes. See the Quick Selection Guide on pages 4 and 5. Specific application requirements can normally be met by selecting optional components, such as switching elements, diaphragm systems and pressure ports. See How to Order on page 3. Certain applications may require customized specials. Consult the SOR representative in your area or the factory.
