No matter what industry you work in, diaphragm seals (also referred to as isolators) and welded assemblies are used to protect your pressure and temperature instrumentation from corrosive process media. After decades of making quality pressure and temperature gauges and sensors to help keep processes performing reliably and efficiently, Ashcroft has seen just about every scenario where something can go wrong. One reason we like to share our expertise is to help people like you who may be experiencing a similar issue that we can help solve. In this article, you will learn what a welded diaphragm seal assembly is and how it is used to help mitigate the damaging effects of high temperature, pulsation and vibration endured by your instruments. You will also see how these assemblies can ensure reliable and accurate pressure readings of your process. When you are done, you will find links to additional resources that can help you learn more about related topics.

How many times have you gone to the refrigerator for a glass of milk only to find it has spoiled? How about that classic car you want to drive, just to find the battery dead and tires flat? These are just two examples of how inadequate storage and lack of periodic inspections can significantly alter experiences. Your pressure gauge needs to be stored in a manner that ensures it’s in working order when you’re ready to use it. If not, it could end up damaged or out of calibration.

Thermowells are essential to protecting your thermometer or temperature sensor in your high-pressure or high-temperature applications. They can protect your investment and keep your measurements accurate, no matter how extreme the environment. One of the top questions we receive here at Ashcroft from those in the temperature measurement industry is how to properly fit a thermowell. What measurements are needed? What is a u-dimension and how does it factor in? Many factors are at play, and it can be easy to get the wrong size if you aren’t paying attention.

With more automated and integrated systems running businesses around the globe, there is a growing need to protect system operators. Putting additional safety measures in place can help prevent worker injury or damage to your equipment.

High-purity applications require a particular type of pressure gauge to ensure accuracy, safety and repeatability. The materials from which it’s made and its safety features must be specialized for demanding environments. Do you have the right high-purity pressure gauge for your process? Do you need enough space to have multiple devices measuring your process? Ashcroft’s newly released HPS high-purity pressure gauge with reed switch might be right for you. This article will describe the features of this new gauge and how it can help keep your application, and business, running.

Your business depends on reliable, accurate and safe pressure measurements and instruments to keep running smoothly. Some pressure gauges even offer safety features to ensure that your workers are protected from harm.
