Pressure switches are very common instruments in the process industry, and various kinds of pressure switches are available. Like many instruments, pressure switches need to be calibrated to ensure their accuracy and reliability. Switches are a bit more difficult to calibrate than transmitters. The wrong kind of calibration can cause many errors in the calibration result. In this article, we will look at how to properly calibrate pressure switches.
20 things you should consider when calibrating pressure gauges
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 quite often receive questions regarding the calibration of a square rooting pressure transmitter. Most often the concern is that the calibration fails too easily at the zero point. There is a reason for that, so let’s find out what that is.
Update March 2020: We have a newer blog post on pressure switches, please find it here: Pressure Switch Calibration
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.
