Many calibration technicians follow long-established procedures at their facility that have not evolved with instrumentation technology. Years ago, maintaining a performance specification of ±1% of span was difficult, but today’s instrumentation can easily exceed that level on an annual basis. In some instances, technicians are using old test equipment that does not meet new technology specifications. This article focuses on establishing base line performance testing where analysis of calibration parameters (mainly tolerances, intervals and test point schemes) can be analyzed and adjusted to meet optimal performance. Risk considerations will also be discussed – regulatory, safety, quality, efficiency, downtime and other critical parameters. A good understanding of these variables will help in making the best decisions on how to calibrate plant process instrumentation and how to improve outdated practices.
In this post we share an educational video on how to calibrate weighing scales.
The video goes through the various tests that should be performed during a scale calibration / scale recalibration.
These tests include:
- Eccentricity test
- Repeatability test
- Weighing test
- Minimum weight test

This is the first blog post in the Beamex blog series "Calibration in Times of Digitalization" we will take a look into the future to give you an understanding of hot topics such as Industry 4.0 and Smart Factory, which are on everyone's minds.
You have probably heard of terms such as Digitilization, Industry 4.0 and Smart Factory. But what do these really mean? Many users of these new technologies don’t yet fully grasp them. This is completely understandable and that's why we will gradually bring you closer to these topics in this Beamex blog series and help you enter the future well informed.
Whether on television, in newspapers or on social media, hardly a day goes by without futuristic topics such as digitalization, big data, artificial intelligence and machine learning. But futuristic? Hasn't the future already arrived?
Process instrument calibration is just one of the many maintenance related activities in a process plant. The last thing you want to do is to have your limited resources wasting time performing unnecessary calibrations or using time-consuming, ineffective calibration procedures.
Yet, you need to make sure that all critical calibrations are completed, ensuring the site stays running efficiently with minimal downtime, product quality is maintained, while the plant remains regulatory and safety compliant, and audit-ready.
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.
Topics: Temperature calibration
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!
In this blog post, I will take a short look
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.
