What is calibration? What does measurement calibration mean?
The word “calibration” can be used in different contexts. Here, we are talking about measurement calibration in the world of measurement technology. Formally, calibration is a recorded comparison between a calibrated measuring device and a traceable reference device.
The reference standard may be called a “calibrator”. Logically, the reference will be more accurate than the device being calibrated. The reference device must also be monitored for calibration. With some quantities, the reference is not always a device but can also be a mass, a mechanical part, a physical reference, a reference liquid or gas.
Everything is based on measurements
Measurements are behind many everyday actions we take for granted, like buying food, filling up our car with gas, turning on the lights at home, or taking medicine.
Precise measurements ensure that we get the right amount of food, fuel and energy and that our medications are safe. They ensure communities can function well and provide the foundation for safer, more sustainable businesses and societies.
Calibration is key
Calibration is key to ensuring accurate measurements and helps improve efficiency, compliance and safety, while minimizing emissions, waste and risk.
By helping to ensure that measurement data is reliable and measurement errors are understood, Beamex helps realize smarter business and support sustainable growth – for a safer and more secure world. less instability.
What is an adjustment?
When you perform calibration and compare two devices, you may notice some differences between the two. So it's quite reasonable that you might want to adjust the device being tested for accurate measurements. This process is often called tuning or trimming.
Formally, calibration does not include adjustment but is a separate process. In everyday language, the word calibration sometimes also includes possible adjustment. But as mentioned, the adjustment is a separate process according to most official sources.
Digital calibration data stream
Traditional calibration is performed by using a calibration reference and writing the results manually on a piece of paper.
In the modern electronic and paperless system, everything can be done without paper. Planning can be done within the maintenance management system, from where work orders are transferred electronically to the calibration management system. The calibration management system can electronically download work orders to mobile recording calibrators. When work is done by recording the calibrators, they automatically save the results in memory. Once the calibration job is completed, results can be downloaded from the calibrator to the calibration management software. Finally, the calibration software sends confirmation to the maintenance management system that the job has been completed.
Conclude
Calibration of process equipment is the comparison and recording of equipment measurements with a traceable reference standard. It's important to calibrate so you can be confident that your measurements are valid. Measurement validity is important for many reasons, including safety and quality. For best results and reliability, make sure the calibration uncertainty is small enough. Use a calibrator that has accurate specifications many times better than the device being tested. Ultimately, setting tolerances and calibration frequency should be determined by a number of factors, including the criticality of the device.
About me
Why should you calibrate?
In industrial process conditions, there are many different reasons for calibration. Examples of the most common reasons are:
The accuracy of all measurements decreases over time
Comply with regulations regulating regular calibration
Quality systems require calibration
Money – money transfer depends on measurement results
Quality of products produced
Safety – of customers and employees
Environmental reasons
Many other reasons

Learn about CMM Measuring Machine
CMM measuring machine also known as CMM machine (Coordinate Measuring Machine) is a type of machine used to measure and determine the shape of a complex surface by touching points on that surface or using light, rays, or beams to measure. Measure the dimensions of machine parts. CMM machines have the ability to measure and determine the exact position of points in a 3-dimensional space by touching that surface with a probe.
Right at the moment the probe touches the surface to be measured, the contact sensor on the CMM measuring probe will record information about the position of that touching point. Then, a point will be positioned in the 3-dimensional space that the CMM machine draws. And by touching many times at many different locations of the surface, the CMM Machine easily simulates that surface in 3-dimensional space.
At this time, the measurement results on that space will tell us the actual size and distance of the machine part that we need to measure. CMM machines can not only measure straight line dimensions, they can also measure diameter, radius, curvature, ovality or check the flatness of a surface...
CMM measuring machines are widely used in the manufacturing industry, especially in the mechanical processing industry. Nearly every machining workshop has at least one CMM machine to ensure machining quality and accuracy of machine parts.
However, after a period of use, errors on the parts on the CMM machine will appear. That is why it is necessary to periodically inspect or calibrate the CMM measuring machine to keep the error level within the allowable range.
