pressure gauge | direct drive gauge | liquid filled gauge

This article was originally published on March 7, 2022, by John Girard and was updated on October 21, 2024. 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.

Calibration | pressure gauge | Pressure Instruments

This article was originally published on October 2, 2023, and updated on October 14, 2024. The number of industries that rely on pressure measurement equipment is expansive. The list includes manufacturing, water/wastewater, hydraulics, food and beverage, medical, and pharmaceutical, among others. If you are new to any of these markets, you need to understand the importance of monitoring and maintaining appropriate levels of pressure in the critical processes in your industry. Accurate measurement of pressure in these processes is essential for ensuring safety, control and process efficiency. However, achieving these goals requires periodic instrument calibration. With more than 12 years of specialization in precision instruments, I have witnessed first-hand the consequences of neglecting calibration. As a follow-up to my blog titled, How to Check the Calibration of a Pressure Gauge, this article examines in more detail the circumstances that necessitate this important process, focuses on the three most critical factors of calibration and discusses the considerations associated with each factor. When you finish reading, you will have a solid foundation of knowledge regarding pressure instrument calibration and be ready to dig deeper into the topic with the additional resources provided for your reference.

pressure gauge | absolute pressure | vacuum pressure | Negative Pressure

By: Todd Thomas, Channel Sales Manager
September 18th, 2024

If you have ever been confused about the term negative pressure, you are not alone. One reason the concept is so confusing is that negative pressure is not really negative at all. It is actually positive pressure, but it is negative in relation to atmospheric pressure. Let me explain. Early in my career (while working for an Ashcroft distributor) I had a difficult time with the term ‘negative pressure’. The only thing that I knew about pressure was filling up a balloon, a ball or a tire. How could pressure be negative? It didn’t make sense! I asked anyone and everyone to explain but never received a satisfactory answer. Today, as a Territory Sales Manager for Ashcroft, a recognized leader in pressure and temperature instrumentation - and 16 years of experience under my belt - I now have a clear understanding of negative pressure, and I am in a position to share my insight. In this article, you will not only learn how to answer the question, "What is Negative Pressure?", you will also understand how it relates to other types of pressure. At the end of the article, you will also see links to additional resources that may be beneficial to you.

Ammonia | pressure gauge | Refrigerant Applications

Ashcroft has written other articles on selecting the best pressure gauges or pressure transducers for ammonia applications (see links at the bottom of this piece). However, we noticed we were still getting questions from people about the ammonia element itself. So, for the industry novice, this article will take a step back to address those specific questions. Ashcroft pressure and temperature instruments are used in virtually every type of industrial application, including ammonia, so it is our job to know how they will perform in every situation. Here we will review a couple of ammonia applications, and what to look for when selecting the best pressure gauge for your specific needs. At the end of the article, you will find additional resources that may interest you.

pressure gauge | sanitary gauge

If you work in any industry that involves food, beverages, pharmaceuticals or biotechnology, your challenge is to implement and maintain strict sanitary control over your entire operation to prevent product contamination and protect public health. This means, that every aspect of the manufacturing process, including equipment and instruments you use to keep your systems running smoothly, must also meet certain sanitary and hygienic standards. Ashcroft is a globally recognized leader in pressure and temperature instrumentation, so we understand the unique requirements our products must meet for use in these highly regulated industries. In fact, as a Product Leader for the company's sanitary product line, I am often asked for guidance during our customers' gauge selection process. In this article, you will learn more about the unique safety challenges of these highly regulated industries, the safety standards that are designed for public protection and some factors to consider when selecting the best sanitary gauge for your needs. When you are done reading, you will also be directed to additional resources to help deepen your knowledge of pressure gauges in general.
