We are sometimes asked if it is better to calibrate process instruments in the field, or in a calibration workshop. It is obviously impossible for us to give a correct generic answer for that question. The right answer for each application depends on various things. In this post I have listed a few common arguments for both field calibration and workshop calibration.
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.
One of the questions we get asked most frequently is how often a customer should calibrate his instruments. Unfortunately there is no straight answer to this, at least not one that would always be correct. Instead there is a list of variables that should be taken into account when deciding the calibration period for any measurement device. Let’s take a quick look at these variables.
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.
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.”
As this is a calibration blog, I will begin with writing a short post on a very fundamental thing – what is calibration? But how can I explain shortly what calibration is?
