Gas-actuated thermometers and bimetal thermometers are both commonly used temperature measurement instruments in multiple industries due to their reliability and precision. However, they operate on different principles. No matter what industry you work in, if you require accurate temperature monitoring, understanding these thermometers can enhance both efficiency and safety in your operations. As the temperature product manager at Ashcroft – an industry leader in pressure and temperature instrumentation – I am often asked which of these instruments will be most appropriate for different applications. The answer, of course, depends on several factors. Read this article to compare the mechanics, applications, and advantages of gas-actuated and bimetal thermometers. Links to additional resources will also provide relevant information to help deepen your knowledge of temperature measurement. When you are finished reading, you will be in a better position to select the right instrument for your specific needs.

If you work in process industries like oil and gas or chemical/petrochemical, you know that a thermowell is a critical component that can help ensure the safe operation of your systems. That's because it is the thermowell's job to protect the temperature monitoring instruments from system pressure, high-velocity flow and corrosive media. However, keep in mind that selecting the wrong thermowell to do the job can have negative consequences that will put the safety of your process and your people at serious risk. Ashcroft has been in the temperature measurement business for decades. As the firm's temperature product manager, I know that flanged thermowells are typically the preferred choice for these applications because of their design and cost. In reality, though, even when the cost feels prohibitive, there are certain situations where a Vortex Thermowell may be your only option. In this article, you will learn about the forces that can make a thermowell fail and the factors to consider when determining whether the Vortex Thermowell is worth the added expense. You will also get links to additional resources related to this topic that may be of interest to you.

There are many instruments used for temperature measurement, but electrical temperature sensors tend to be the most common method. A resistance temperature detector or RTD temperature sensor converts the measured temperature value into an electrical signal. But do you know how an RTD actually works? This article will discuss RTD sensors, their function and how they can help provide accurate temperature measurements for your application.
