SOR announced that its 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,” said Jeff Coltvet vice-president of sales at SOR. “We decided to make an investment in assuring we provide our customers exactly what they need and actively pursued getting the SIL approvals.”

The SOR line of pressure switches and level switches are rugged field-mounted instruments. Nearly every SOR product can be designed to meet the demands of your process and custom built to your exact specifications.
