If you work in an industry that involves hydrogen, or other volatile substances, you understand the dangers that you and your team face daily. But do you know that any equipment used in these environments (aka hazardous locations) must meet certain requirements and be designed to help contain or prevent a fire or explosion from occurring in the first place? For example, certain pressure sensors like the E2F Flameproof and E2S Intrinsically Safe pressure transducers are built to withstand or prevent explosions and fires in hazardous locations. This makes them effective options for managing pressure in complex industrial applications. Ashcroft is a recognized leader in pressure and temperature instrumentation and has been for more than a century and a half. In my role as product leader, I am familiar with the complex nature of hydrogen and have been educating customers on how to select the best sensors to meet the stringent quality and safety requirements for highly combustible environments. This article will explain the factors and classifications of a hazardous location, the product certifications that are required for use in these environments and the solutions available to help keep you and your team safe. When you are done reading this article, you will have a better understanding of what type of pressure transducer you will need for your application and be ready to take the next step in your purchasing decision.

Now more than ever, industrial leaders are taking measures to protect the environment. For example, if you are in the HVAC/R business you may be using a more ecologically friendly refrigerant compound like ammonia to help reduce your energy consumption and greenhouse gas emissions. If this is the case, you need to be aware of certain risks and solutions that can help minimize potential danger. According to the American Society of Heating, Refrigerant and Air-Conditioning Engineers (ASHRAE), ammonia is an ideal alternative to traditional chlorofluorocarbon refrigerant compounds because of its low impact on the environment. However, in certain quantities, ammonia can also be hazardous to people and animals. That’s why systems with ammonia and similar refrigerant-based compounds need to have quality components, including pressure sensors. In some ammonia-based systems – such as those used in fuel pump controls – using the wrong kind of OEM pressure transducer could lead to leaks or bursts that cause serious harm to operators and equipment.

For the industry novice looking to understand the basics of pressure measurement instruments, it can be confusing and overwhelming to search through the seemingly limitless number of available transmitters and transducers.

Liquefied gases, such as nitrogen, oxygen and helium, are used in many cryogenic applications. To measure pressure in these situations, your pressure instruments must be able to stand up to very low temperatures. So, how can you effectively measure process pressure when your pressure gauge is not rated for such a low cryogenic temperature? In this article, I will discuss cryogenic applications, and the different mounting options and accessories available that can help protect your pressure instruments from the effects of very low temperatures.
