Pressure gauges are often used in challenging environments where they could be exposed to extreme temperatures that may damage them or impact their accuracy. These extreme temperatures can come from a variety of sources such as the surrounding environment (ambient temperature), or the temperature of the process media being measured (media temperature). How do you minimize the effects of temperature on your instrumentation and protect your pressure gauges from damage? Read on to learn the effects that temperature can have on pressure gauges and their performance. Plus, you will gain insights into how you can address these issues to keep your gauge working at peak performance.

Pressure gauges can be found in virtually every industry. Depending on your application, these instruments play an important role in measuring the air, gas or liquid pressure in your system to keep it running safely and smoothly. However, for optimum efficiency, you will need to make sure the pressure range you choose for your gauge aligns with your application requirements and a few other factors. Ashcroft has been in the pressure gauge business for more than a century and a half, so following the guidelines in this article can save you time and give you confidence in your purchasing decision. Read on to learn about the factors to consider when choosing the pressure range for your gauge. Then, when you are done, we will share additional information about pressure gauge selection that you can use as a reference.
