## Voting Logic in Safety Instrumented System (SIS)

There are 1oo1, 1oo2, 2oo2, 2oo3 etc voting logic in the safety instrumented system architecture. The voting logic architecture usually used in the field instrument and or final control elements to reach certain Safety Integrity...

## What is Safety Instrumented Functions ?

A Safety Instrumented Function, or SIF, is one or more components designed to execute a specific safety-related task in the event of a specific dangerous condition. The over-temperature shutdown switch...

## Safety Instrumented Burner Management System

One “classic” example of an industrial automatic shutdown system is a Burner Management System (or BMS) designed to monitor the operation of a combustion burner and shut off the fuel...

## Proof Testing of Safety Instrumented Systems

A reliability enhancing technique related to preventive maintenance of critical instruments and functions, but generally not as expensive as component replacement, is periodic testing of component and system function. Regular...

## High Reliability of Safety Instrumented Systems

Instrumentation safety may be broadly divided into two categories: the safety hazards posed by malfunctioning instruments, and special instrument systems designed to reduce safety hazards of industrial processes. This section...

## Failure rate and MTBF of Safety Instrumented Systems

In reliability engineering, it is important to be able to quantity the reliability (or conversely, the probability of failure) for common components, and for systems comprised of those components. As...

## Applying Probability Laws to a Safety Instrumented System

The relatively simple concepts of AND and OR Boolean functions become surprisingly complicated when applying them to real-life measures of component reliability, mainly because reliability is measured in multiple ways....

## Safety Instrumented System Probability

While the term “probability” may evoke images of imprecision, probability is in fact an exact mathematical concept: the ratio a specific outcome to total possible outcomes where 1 (100%) represents...

## SIS – Safety Instrumented System Example

A Safety instrumented system (SIS) consists of an engineered set of hardware and software controls which are especially used on critical process systems. SIS – Safety Instrumented System Example Examples...

## S84 / IEC 61511 Standard for Safety Instrumented Systems

IEC 61511 is a technical standard which sets out practices in the engineering of systems that ensure the safety of an industrial process through the use of instrumentation. Such systems...
