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.

Your cell phone, computer, television, car and any other electronic device you use each day all depend on semiconductor applications to exist. But these demanding applications require specialized high-purity equipment and instruments to run safely, efficiently and properly. Pressure transducers (and pressure transmitters but for simplification in this article I will refer to them as "pressure transducers") are crucial to the semiconductor process, but only if they are manufactured a certain way to handle hazardous environments. How do you know what makes the best semiconductor pressure transducer?

Your pressure transducer can be used in a variety of applications, many of which are exposed to the elements. Rain, snow, wind and sunlight can all have an impact on your pressure instrument if you don’t have the right equipment for the job. Using the correct electrical connector for your pressure transducer can ensure that your equipment keeps running even when impacted by the environment. But how do you choose the best electrical connector for your application? This article will discuss the factors to consider when selecting an electrical connector for a transducer that can stand up to the environmental impacts of your application.

Pressure transducers used in the semiconductor industry need to be designed and manufactured with materials that can prevent contamination in your process, and also handle corrosive liquids or gases in certain applications such as cleaning equipment and wet stations. Ashcroft has recently released the ZL95 fluoropolymer pressure transducer with a 4-digit LED display, specially made for corrosive environments. The PTFE/PFA wetted parts provide extended cycle life and corrosion resistance. This review will look at the features of this pressure transducer and how it can provide reliable pressure measurements for your semiconductor application.
