SOR Switches Certified for SIL Environments

SOR achieves SIL (Safety Integrity Level) certification for its pressure and level switches

SOR® pressure and level switches are certified for use in IEC 61508 SIL applications.

SOR announced today that the company’s line of pressure, differential pressure, temperature, vacuum and level switches have been certified fit for use in SIL (Safety Integrity Level) environments. SOR is one of only a few manufacturers in the industry to offer its entire range of switches certified to IEC 61508 safety standard.

To obtain SIL certification, the products were assessed by FM Approvals per the requirements of IEC 61508 Parts 1, 2, and 3. When implementing Safety Instrumented Systems (SIS) in process plant environments such as power plants, offshore oil platforms, refineries and chemical plants, the SIL certification helps mitigate risk at the process instrument level.

“Many customers are now requiring SIL certified products as safety is a high priority to them. We decided to make an investment in assuring we provide our customers exactly what they need and actively pursued getting the SIL approvals”, says Jeff Coltvet Vice-President of Sales at SOR.

The SOR line of pressure switches and level switches are rugged field-mounted instruments.
