SIS Proof Testing

SES provides services in the area of SIS (Safety Instrumented System). SES engineers can work with your designated plant personnel to gather operational and maintenance data, then plan and develop SIS proof testing procedures.

During a typical SIS proof test, our specialists inspect each SIF (Safety Instrumented Functions), including the sensors, logic solvers, and final elements.

They document any faults or deficiencies, call them to the attention of your staff, and in many cases, our specialists will be able to correct them at your request.
