Advantages of a Three-in-One Field Safety Transmitter

A typical Safety Instrumented System (SIS) consists of a Safety Integrity Level (SIL)-certified sensor, logic solver, and final element. These SIS systems can be complex, including multiple components such as a pressure or temperature transmitter, safety relay, programmable logic controller (PLC).  Also, it can include a trip amplifier; and requires intensive wiring and programming. See …

Why would I use a switch over a transmitter?

Switches are no longer the blind, “dumb” electromechanical devices of a generation ago. Signals from sensors in critical safety loops (e.g. protecting against high temperature or pressure) are typically integrated with the plant control system via a discrete or analog input channel.  A switch provides a binary (on/off) input, while transmitters provide a continuous (4 …

What is SIL?

When looking for different instruments to place in your application, it is always important to understand the safety requirements of your environment. You will often hear of the requirement to use an explosion-proof or an intrinsically safe device. Another requirement often thrown into the ring is the term “SIL”, an acronym for “Safety Integrity level”. …

Preventative Maintenance and Self Diagnostics

Instrumentation operating within hazardous areas in petrochemical refineries are subject to challenging conditions. When instrumentation falls out of calibration and fails to provide basic process control, unplanned shutdowns often occur. Similarly when the instrumented safety function fails to provide protection, injuries and deaths can unfortunately occur. Preventive maintenance (PM) is essential to the safe and …

The Case for Electronic Switches in a Digitized Plant

Electro-mechanical switches were once ubiquitous in industrial plants. With the advancement of instrumentation technology, the apparent limitations of these switches has become more obvious over time.   For example, plant operators demanded greater accuracy and repeat ability from process monitoring/control instrumentation, something which could not be fulfilled by mechanically-operated switches. The same end users also …

Should I Keep Using a Switch or Upgrade to a Transmitter?

The answer might surprise you! In industrial applications, a “switch” typically means “a snap acting electrical component that is combined with a process sensor to provide electrical switch output and take action to alert or control a process”. While a transmitter is defined as, “an instrument that continuously monitors and provides information about a process …
