Calibration out of tolerance – ready to hit the Panic button?
In this post we are talking about calibration being “Out of Tolerance” (OoT).
When you calibrate something and the result is a “Fail”, then it is an Out of Tolerance-situation.
But it’s not all that simple - there is more to it and more things to be considered.

This is the second blog post (out of three) continuing on the subject of calibration uncertainty. In the first blog post we discussed the basics; how important it is to be aware of the uncertainty, short terminology and the classic “piece of string“ example. If you missed the Part 1-blog post, you can find it in the below link. If you want to get all the parts at once, feel free to download the related full white paper from the link below.

The oil and Gas industry in the North Sea has been hit by a Perfect Storm – the rapid fall in the price of oil to levels less than the average extraction cost has resulted in the delay or cancellation of a huge number of investment projects.

If you don’t know the measurement uncertainty, don’t make the measurement at all!
In the previous blog post Ned discussed the basics of loop calibration.
Now, let’s watch a video on the same subject.

Last year, I presented a paper on this topic at an ISA event (Power Generation Division meeting). My opinions are based on customer feedback and what I have learned from them over the years.

Getting calibration software is much more than just selecting the right product and buying the necessary amount of licenses. The hardest part is actually to get people to use the calibration software in the right way. And especially within a set project budget and time limitations. To achieve this, you should see the calibration software implementation as a project with certain steps.
The temperature transmitter is a popular instrument in process plants. Like most transmitters, it needs to be calibrated to assure that it is operating accurately. So, let’s take a look at how the calibration is done!
