Temperature measurement is one of the most common measurements in the process industry.

Every temperature measurement loop has a temperature sensor as the first component in the loop. So, it all starts with a temperature sensor. The temperature sensor plays a vital role in the accuracy of the whole temperature measurement loop.

As any measurement instrument you want to be accurate, also the temperature sensor needs to be calibrated regularly. Why would you measure temperature, if you don’t care about the accuracy?

In this blog post, I will take a look at how to calibrate temperature sensors and what are the most common things you should consider when calibrating temperature sensors.

In this blog post, I will share with you a two-part webinar series titled “How to calibrate temperature instruments”. We did this webinar together with our partner ISA (International Society of Automation).

The webinars covers some theory, many practical things, demonstrations of temperature instrument calibration and Questions & Answers sections.

In some earlier blog posts, I have discussed temperature calibration and calibration uncertainty. This time I will be covering the different uncertainty components that you should take into account when you make a temperature calibration using a temperature dry block. 

Making a temperature calibration using a dry block seems like a pretty simple and straight forward thing to do, however there are many possible sources for uncertainty and error that should be considered. Often the biggest uncertainties may come from the procedure on how the calibration is done, not necessarily from the specifications of the components.

Let’s turn the heat on!

Learn about temperature, temperature scales, temperature units and temperature unit conversions.

A HART transmitter is the most common smart transmitter type used in the process industry. What should be taken into account when calibrating and trimming a HART transmitter? Let’s take a look at the most important things to take into consideration. And also, let’s set straight the most common misconceptions regarding HART communicators.

We often get asked questions regarding the calibration of a pressure switch.
Since we didn’t have any videos on the topic on our YouTube channel, our dynamic duo from our US office, Roy and Ned, decided to make one.

Hi all,

In this blog post we’ll continue to talk about another fundamental topic:
Why should you calibrate?

It is good to remember the old rule: “All measurement devices measure wrong, and calibration tells how wrong they are.”
