SIL
Safety Integrity Level (SIL) is defined as a relative level of risk-reduction provided by a safety function, or to specify a target level of risk reduction. In simple terms, SIL is a measurement of performance required for a Safety Instrumented Function.
We offer a wide range of SIL-rated temperature, pressure and flow sensors, and valve positioners. Various solutions are available; from high integrity transmitters with full redundancy (Hardware Fault Tolerance = 1) designed and certified by TUV against IEC 61508 requirements to standard transmitters with enhanced internal diagnostics to minimize the Probability of Failure on Demand.
The positioner is available with a shutdown module allowing for overriding of the control action in case of demand. All of these include third party calculations / evaluation of safety performances / lambda to enable SIL loop calculation / assessment.
