What about power for the ONE Series?

The ONE Series was designed to work with the leakage current from process controllers, and therefore it is a specialized switch like no other: it brings the benefits of electronic switches and smart sensors, with no extra penalty on additional power wiring. The final user can just replace their mechanical switch by the ONE series …

Tradeoffs of different antenna types

We recently had a case where our customer needed to place a detector high on a tank and the nearest gateway was about 150 ft below the walkway. There were not enough wireless instruments to relay the signal and the antenna was fixed to the detector. The device would not sync with the gateway until …

One Series: Smart switch upgrade or SIL rated transmitter?

To get ‘blue’ or to get ‘yellow’, that is the question… in the field. No matter whether you are in an oil rig or in a manufacturing line, the need to keep the plant up and running is paramount. Many industrial plants use our standard ‘blue’ product line, the One Series Smart Electronic Switch This …

How often should I calibrate my gas detector?

When we think of gas detector calibration and how often it must be performed, it is dependent on many variables. First and foremost is determining if a gas sensor is out of calibration. The best way to establish this is through a “bump” or functional test using a certified standard gas mixture of known concentration. …

Wired vs. Wireless

Instrumentation today is far more capable and advanced than just a decade ago. Microprocessors continue to get more powerful and continue to reduce the power needed to perform tasks.  However, the smart detectors and sensors today can operate reliably for years on a battery without any loss of performance. With wireless technology able to carry …

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 …
