Uncertainty components of a temperature calibration using a dry block

Uncertainty components of a temperature calibration using a dry blockIn this article, we will be covering the different uncertainty components that you should consider 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.

 

Pt100 temperature sensor — useful things to know

Pt100 temperature sensor — useful things to knowPt100 temperature sensors are very common sensors in the process industry. This article 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.

 

Thermocouple Cold (Reference) Junction Compensation

Thermocouple Cold (Reference) Junction CompensationEven people who work a lot with thermocouples don’t always realize how the thermocouples, and especially the cold (reference) junction, works and therefore they can make errors in measurement and calibration.

In this article, we will take a short look at the thermocouple cold junction and the cold junction compensation. To be able to discuss the cold junction, we need to take first a short look into the thermocouple theory and how a thermocouple works.

We won’t go very deep in the theoretical science but will stick more with practical considerations, the kind of things you should know when you work with thermocouple measurements and calibrations in a typical process plant.

 

Temperature units and temperature unit conversion

Temperature units and temperature unit conversionThis article discusses temperature, temperature scales, temperature units and temperature unit conversions. Let’s first take a short look at what temperature really is, then look at some of the most common temperature units and finally the conversions between them.

 

How to calibrate temperature sensors

How to calibrate temperature sensorsEvery temperature measurement loop has a temperature sensor as the first component in the loop. So, it all starts with a temperature sensor. The temperature sensor plays a vital role in the accuracy of the whole temperature measurement loop.

As any measurement instrument you want to be accurate, also the temperature sensor needs to be calibrated regularly. Why would you measure temperature, if you don’t care about the accuracy?

In this article, we will take a look at how to calibrate temperature sensors and what are the most common things you should consider when calibrating temperature sensors.

 

AMS2750E heat treatment standard and calibration

AMS2750E heat treatment standard and calibrationIn this article, we will take a look at the AMS2750E standard, with a special focus on the requirements set for accuracy, calibration and test/calibration equipment.

The AMS2750E is predominantly designed for heat treatment in the aerospace industries. Heat treatment is an essential process for many critical parts of an airplane, so it is understandable that there are tight regulations and audit processes set.

While the results and success of some other industrial processes can be relatively easily measured after the process, this is not the case in a heat treatment process. Therefore, very tight control and documentation of the heat treatment process is essential to assure the quality of the end products.

 

Optimal testing parameters for process instrument calibration

Optimal testing parameters for process instrument calibrationMost 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 paper focuses on establishing base line performance testing where analysis of testing 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.
