The implications of failing to detect gas leaks can impact the environment and workers’ health. Facilities are turning to smart, connected technologies when it comes to the accurate detection of odorless and invisible gases. Below are three ways automation can help improve gas detection. Deploy wireless sensors to increase monitoring density Deploying wireless sensors is a
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
A Dual Switch has (2) independent micro-switches in one housing. Most commonly, a dual switch contains 2 SPDT (Single Pole, Dual Throw) switches. The key point is that there are two independent set points, each switch with its own mechanical actuator. A Dual switch is chosen if two independent set points are needed, or the user
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
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
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
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
For a long time, process transmitters have been the only game in town when it comes to measuring devices in Instrumented Protective Systems (IPS). However, most brands of process transmitters today are dependent on logic solvers (like PLCs) and therefore do not have the diversity or physical separation recommended by the latest safety standards to
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
The One Series is our smart electronic switch with a variety of different models including low capacity and high capacity switch outputs, transmitter options, and a variety of other useful features. More information can be found in our technical brochure for the One Series models. In order to summarize some of the benefits of using
