Perhaps the simplest form of sensor providing process information for a safety instrumented function is a process switch. Examples of process switches include temperature switches, pressure switches, level switches, and flow switches. SIS sensors must be properly calibrated and configured to indicate … See more Control hardware for safety instrumented functions should be separate from the control hardware used to regulate the process, if only for the simple reason that the SIF exists to bring the process to a safe state in the event … See more When a dangerous condition in a volatile process is sensed by process transmitters (or process switches), triggering a shutdown response from the logic solver, the final control … See more One “classic” example of an industrial automatic shutdown system is a Burner Management System (or BMS) designed to monitor the … See more A common way of ranking the dependability of a Safety Instrumented Function (SIF) is to use a simple numerical scale from one to … See more A SIS is intended to perform specific control functions to prevent unsafe process operations when unacceptable or dangerous conditions occur. Safety Instrumented Systems must be independent from all other control systems that control the same equipment in order to ensure SIS functionality is not compromised. SIS is composed of the same types of control elements (including sensors, logic solvers, actuators and other control equi…

WebJul 24, 2024 · Safety Integrity Levels (SILs) are a measure of the impact that a Safety Instrumented Function (SIF) has over the risk associated with a specific hazard. The higher the SIL level is, the more efficient that function will be at reducing the risk it mitigates. SIL 3 is one of the safety integrity levels defined by the IEC 61508 standard. WebApr 3, 2024 · Abstract. Instrumented protective function (IPF) is a safety function designed to achieve a safe state for a specific hazardous event. An IPF loop is made up of initiators, logic solvers and final elements. IPF is classified with a specific safety integrity level (SIL), which must be met throughout its life-cycle. IPF failures can cause severe consequences …
