Calibration is a fork of procedure that compares a known measurement, which we know as the standard, against the measurement of the tools using the instrument.
Typically, the accuracy of the standard should be ten times the accuracy of the measuring device that is being tested. However, an accuracy ratio of 3:1 is acceptable by most standard organizations.
Know that the control provides preventive field services to assist you in ensuring the calibration and control of the instruments such as Rotary Shouldered Connection.
The Objective Of Calibration Behind Measuring Instruments:
Calibration of the measuring instruments has two objectives. First and foremost, it checks the accuracy of the instruments. And the second objective behind such a calibration is that it determines the traceability of the measurement.
The calibration expert will provide a report. The report will show the error in measurements with the measuring device before and after the calibration.
To explain the calibration methodology, one can use an external micrometer as an example. With it, the scale’s accuracy will be the main parameter for calibration.
In addition to this, these instruments, take API 7-2 for example, are also calibrated for zero error in the fully closed position and flatness and parallelism of the measuring surfaces.
A simple slip gauge can be useful for the calibration of the scale. A calibrated optical flat will also be used to check the flatness and parallelism.
The Importance Of Calibration:
The accuracy of all measuring devices tends to degrade over time. This is one of the typical things that could be caused by normal wear and tear. However, such alteration in precision can also be caused by electric or mechanical shock. If need be, it can be used in a hazardous manufacturing environment.
Depending on the type of instruments, and the environment in which the machinery will be used, it may degrade quicker than one could imagine. It may also happen that it may take over a long period. The bottom line is that the calibration will improve the functionality of the machinery, namely the measuring devices.
We all know how measuring devices tend to improve product quality. So, with it, you will have a fuss-free operation.
When Should I Be Calibrating?
Many signs indicate that your measuring device should be calibrated. We have mentioned them below.
- You must calibrate the devices based on the recommendation of the manufacturer.
- After any mechanical or electrical shock, you may calibrate the devices.
- Conducting a periodic calibration, be it annually, quarterly, or monthly.
The costs and risks of using un-calibrated devices are higher than you can imagine. Therefore, it is advised to calibrate the measuring instruments through a reputable company.
This will ensure error-free functionality. Moreover, by doing so, you will be ensuring that the errors at least associated with the measurements are in the acceptable range.
Ending note:
Now that you know the significance of calibration ensure that the measuring devices are periodically put through a calibrated session. This will also heighten your reputation in the market as well.
