Regardless of the industry, if your system requires a pressure gauge to measure and monitor process pressure, you want to ensure it offers the accuracy, safety and quality features you need. That includes protection from excessive pulsation and/or vibration found in challenging conditions. While there are many types of pressure gauges to choose from, the challenge is finding the one that works best for your specific situation. Liquid-filled pressure gauges, direct drive pressure gauges and dampened movement options like Ashcroft’s PLUS!™ Performance all have pros and cons to consider. As a leading authority in pressure gauges, Ashcroft helps customers like you understand the advantages and drawbacks of different products so you can make a more informed purchasing decision. Read this article to learn about the types of pressure gauges available for applications with high vibration, pulsation and other demanding conditions. When you are done you will be able to decide which one is best for your application. You will also find additional resources that can answer other common pressure gauge questions.

Oil & gas, water/wastewater, chemical and petrochemical industries rely on accurate and repeatable pressure measurement instruments to ensure processes run safely and efficiently. However, without proper protection, the internal (wetted) components of those pressure gauges, transmitters, transducers and switches will become damaged from the corrosive materials found in these harsh applications. Diaphragm seals are the ideal solution for protecting your pressure sensors from potential damage because they can isolate the sensing components from the process media. But choosing the right diaphragm seal for the job requires you to consider which wetted materials are best suited for your specific application. Ashcroft can help. We have been an industry leader in pressure and temperature instrumentation for decades and often help our customers address this very challenge. In this article, you will learn the four factors to consider when choosing your diaphragm seal material. When you are done reading, you will have the information you need to be more confident in your purchasing decision. You will also see additional related resources to address other diaphragm seal questions you may have .

For applications that may expose instrumentation (such as pressure gauges, pressure switches or pressure transmitters) to clogging or corrosion it is appropriate to isolate the instrument from the process.
