For instance, the pressure of a home water system does not necessarily need to be as precise as a medical sterilizer. However, over time, even the highest quality pressure instruments can become less accurate due to factors such as wear and tear, environmental conditions, and mechanical stress. This gradual decline in accuracy poses can lead to inefficiencies, safety risks, and compromised operations, making it critical to periodically calibrate your instruments to ensure they provide accurate readings. During my 13 years as a precision product leader at Ashcroft, I am often asked how calibration is done. Read this article to learn what is involved in pressure gauge calibration and the instruments you can use to ensure it is done correctly. At the end of the article, you will also see links to additional resources to help deepen your knowledge on this subject and more.

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.

In your most challenging applications, safety is the number-one concern. I’m sure you’re always thinking about ways to keep workers safe and equipment functioning properly because downtime is not an option.
