SOR Process Instrumentation

SOR Pressure Switches have been the industry gold standard for more than 60 years and are suitable for a wide variety of continuous pressure applications. SOR pressure switches and transmitters can be custom engineered to fit specific application requirements by selecting optional components, such as switching elements, diaphragm systems or pressure ports.

SOR Level Switches are either float- or displacer-operated. These rugged products feature few or no moving parts and are available with flanged or sealed chambers or as insertion models. SOR level switches and transmitters can be custom engineered to fit specific application requirements by selecting optional components, such as switch type and number, housing type, chamber material, process connections, accessories and more.

SOR Temperature Switches consist of a pressure switch that has a sealed temperature sensing bulb attached directly to the pressure port. Corrosive service or particular customer requirements may require custom engineered, optional components such as housings, switching elements and accessories.

SOR Flow Switches are either vane operated or thermal differential. Vane-operated switches are magnetically actuated and designed for direct sensing of liquid flow in pipelines. Thermal differential switches measure liquid flow, level or interface by sensing changes in the thermal heat transfer characteristics of the media where it is located.

SOR Nuclear Switches are specifically targeted to meet the demands and provide solutions for the nuclear power generation industry. Many older nuclear power plants are now confronted with discontinued or obsolete product issues. At SOR, we can custom engineer a variety of 1E-qualified mechanical pressure, vacuum, and temperature switches to meet your specifications.
