If you work in oil and gas, chemical and petrochemical, or any other industry that involves high heat, your challenge is to find instruments that are designed to withstand the extreme temperature conditions of the environment and your process media. For example, pressure gauges have specific temperature ranges. If your application goes beyond the instrument's limits, you may need to add an accessory to maintain the integrity and accuracy of your gauge. As the accessories product leader at Ashcroft, part of my job involves educating customers and distributors about the options available to keep their systems running safely and efficiently. In this article, you will learn how to protect your pressure gauges from getting damaged in harsh applications. You will also see links to additional articles and resources that will help deepen your knowledge of pressure gauges and the accessories that support them.
