Fixed gas detection for temporary monitoring

Gas detection is a key part of a modern plant’s safety and asset monitoring system.  Most plants likely have a permanent gas detection setup to alert operators when there are critical issues.  Temporary systems can help when a permanent solution isn’t needed. What isn’t thought about as often is areas that may not need gas …

How to wire a SPDT mechanical switch

Determining the wiring configuration (Normally Open or Normally Close) to a SPDT mechanical switch can seem confusing at times. However, the concept behind it is relatively straightforward. Wiring arrangement depends on 2 things: Whether the application is on the rise (i.e., trip above setpoint) or on the fall (i.e., trip below setpoint) Whether the load …

Switch information for instrumentation engineers

The worst nightmare for instrumentation engineers and technicians is a call due to an unexpected shutdown. Many plants are complex systems of highly technical equipment and machinery intertwined to accomplish their production function.  Regardless of whichever problem occurs, the goal for the day is to get back to business as soon as possible, which includes …

Artificial Intelligence in process instrumentation

The data bottleneck may be starving Artificial Intelligence from its full potential, yet AI usage in operations is accelerating. It was not long ago end users were telling vendors to stop providing more data unless they can easily explain to them how it can be used to improve their bottom line. Perhaps Big Data got …

Mechanical Switch vs. Electronic Switch: Savings upgrade

Many times, when specifying replacement switches I&E technicians may feel most comfortable replacing “like-with-like”, and stick with a mechanical switch. Users may be acclimated toward electromechanical switch maintenance and may not be fully  aware of the hidden maintenance costs vs. those associated with an electronic switch serving the same function. Electromechanical switches are built from …

Mechanical Switches solve modern industrial problems

Back in 1681, Denis Pepin designed the first pressure relief valve to keep his experimental steam chamber from exploding. His idea was simple – to use the process’ own power as the safety operator, rather than an external system. Fast forward to 1931 when the modern rupture disc was invented using the tensile strength of …

Triggering alarms with wireless gas detection

With the advancement of wireless technologies, wireless devices have become common place for industrial process applications. As outlined in some of our previous blogs, wireless technology is also being utilized more often for gas detection at various levels of the plant safety system. This is usually accompanied by the need to have a local alarm …

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 …
