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.

If you work in a chemical manufacturing facility, water treatment center or oil/gas refinery, you likely use pump systems to transfer products between different stations. Suction and discharge installations can be particularly problematic environments for the instruments used to monitor the pressure in these systems. If your instruments get damaged, the entire process can break down, so protecting them is a priority. Ashcroft has been a major contributor to water/wastewater pressure and temperature instrumentation for decades, so we understand the challenges of keeping instruments protected in harsh environments. Read this article for our recommendations for keeping your pressure gauges, switches, and sensors working properly, regardless of where they are positioned during pump system installations. Once you have finished reading, you will be equipped to determine the most suitable approach for your needs. Additionally, you will have access to relevant articles and guides to help keep your systems running smoothly.

Some pressure instruments require a fill fluid to help with pulsation and vibration in certain applications. Filling the cavity of a pressure gauge with liquid lubricates and dampens the internal components to reduce or eliminate the effects of heavy vibration and/or pulsation. A system fill is commonly used in assemblies when one or more instruments are installed above a diaphragm seal. There are many types of fill fluid options available today, so which one is best for your application?
