This article discusses some critical items to address for a calibration program based on sound metrology fundamentals without a complete overhaul of the calibration program. Having properly calibrated process control instrumentation provides a high quality of process control, a process that will operate to design specifications, and prevents the process from being stressed as it compensates for inaccurate measurement data feeding the DCS. Realization of these benefits may be challenging to quantify and attribute to implementing any of the suggested changes, but conversely, implementation of the changes should not be extraordinarily burdensome on resources.  

The Pt100 temperature sensors are very common sensors in the process industry. This blog post discusses many useful and practical things to know about the Pt100 sensors. There's information on RTD and PRT sensors, different Pt100 mechanical structures, temperature-resistance relationship, temperature coefficients, accuracy classes and on many more.  

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

In this blog post, I will discuss the most common data integrity pitfalls in the calibration process.

Whether the calibration process is fully paper-based, or partially utilizing documenting calibrators, or even fully paperless, there are places in calibration processes where data integrity most commonly is jeopardized and needs special attention.

How often should instruments be calibrated? That is a question we get asked often. It would be nice to give a simple answer to that question, but unfortunately, that is not possible. Instead, there are several considerations that affect the answer of a correct calibration period. In this post, I will discuss these considerations.

In this post, I would like to talk you about the Ohm’s law. Why? Because it is helpful in many practical every-day situations, especially if you are an instrument technician. We often get questions that can be answered with an answer derived from the Ohm’s law.

This post includes the recordings of the two-part webinar series titled “How to avoid the most common mistakes in field calibration” we recently did together with our partner ISA (International Society of Automation).

This post discusses calibration in hazardous area in the process industry. 

In this blog post, I will take a short look on thermocouples and especially on the cold junction and the different cold junction compensation methods.

In this blog post, I explain how a resistance or RTD meter works and the difference between the 2, 3, and 4 wire connections.
