      Nuclear Qualified Pressure Switches

      SOR nuclear-qualified pressure switches remain relevant in today’s ageing power plants. Our engineering has proven to be a “go-to” resource because we have been involved since the beginning. We specialise in replacement units as well as new-build units and are happy to work with your engineers to help design pressure switches to meet unique and special needs.

      Nuclear Qualified Temperature Switches

      The most popular SOR nuclear qualified pressure instruments can also serve as temperature switches with a few modifications. Each switch is engineered to your specifications and thoroughly tested for quality of construction and performance before shipment. They meet the strict requirements of the nuclear power generation industry and may be mounted directly or in a remote location.

      Engineered Solutions for the Nuclear Power Industry

      Our engineering expertise is specifically targeted to meet the unique demands of the nuclear power generation industry and provide solutions for obsolescence issues and improve process efficiency. We call it custom engineering and today we build a variety of 1E-qualified mechanical pressure, vacuum, temperature and differential pressure switches to meet your specifications.
