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 …

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 …

Wireless gas detection, a look back on how we saw the future:

Wireless gas detectors in permanent monitoring applications are rapidly being accepted to meet increased need to provide detection coverage when budgets are constrained. I took a quick look at a prior blog from our marketing team posted earlier, Safety: Wireless has matured, gas detectors have too.  Things have not changed much since that post. Andy was discussing how wireless can fit …

Selecting the Right Pressure Switch for Your Application

Pressure switches are widely used within many applications in industrial facilities. The basic function of a pressure switch is to detect a pressure change and convert it into an electrical function – typically on/off or off/on. These products have been around for decades but sometimes customers still need help when looking to select a pressure switch to solve a problem or improve the …

Embracing the New while Remembering the Old!

After working from home for the past few weeks I have a newfound appreciation for wireless technologies. Having to share the home office with my wife and son, both of whom are working from home, wireless connections made all the difference. It would have been logistically impossible to wire all our work devices to the …

6 Reasons to Deploy WirelessHART Toxic and Combustible Gas Detection 

Using wireless communication for tough industrial applications is not a new concept. In fact, the technology has been around for more than 30 years, with the use of proprietary radios. However, with the modernization of industrial networks and the emergence of the Industrial Internet of Things, there has been an increasing demand for secure standardized industrial wireless technologies, or open …
