The calibration of measuring instruments (สอบเทียบเครื่องมือวัด) could be of several types depending on the inaccuracy which a device is showing. For example, if the device shows an inaccuracy related to temperature, it requires a temperature calibration. On the other hand, if a pressure measurement device shows inaccuracy, it would require a pressure calibration. Thus, several types of calibration are done for various measurement devices. Any measurement device should show accurate results. Ideally, it is not showing it is completely hazardous.
To check what kind of calibration it requires d you should consult an expert as they could tell it easily. Anybody who is thinking of calibrating the device should know about calibration before taking the step. Calibration is great for the life of your device, as these devices are very costly and could not be purchased again and again. Therefore calibrating them at periodic intervals can save you from high charges and risk. Usually, the calibrations are carried out in open areas, and some on-bench calibrations are also popular.
- Temperature Calibration
Any person who uses a thermometer, humidity generator instrument, or instruments at a weather station may require temperature calibration. An instrument that has an input or output related to temperature would surely require the kind of calibration. These instruments required these calibrations as due to the increased and decreased humidity, their result gets changed. With the changing results, the error in the final output changes consistently; therefore, it is important to go for the calibration process. Remember, this type of calibration is only carried in an inner space and never done in a field area.
- Pressure Calibration
An instrument that measures the pressure, such as barometer, transmitter, and test gauges, requires pressure calibration. When an instrument undergoes pressure calibration, it is run against a calibrator, and the pressure of hydraulic gas is measured. In addition, there are some instruments in which the pressure of air is also measured. Afterward, its pressure is converted to the ideal rate by using a calibrator.
- Mechanical Calibrator
An instrument such as micro m, scales, and balances requires a mechanical calibration. Calibration is usually done for correcting the results of factors such as force, mass, and vibration. Sometimes the torque value in the instrument is also deflected; the mechanical calibration process manages it completely. This kind of calibration is really important for a physics laboratory to get accurate results.
- Electrical Calibrator
Any calibrator required to test instruments such as clamp meter, insulation tester, and other electrical instruments needs to undergo electrical calibration. Any instrument that measures the frequency of a substance, the voltage of current all the resistance offered by any wiring can undergo electrical calibration. These are the substances that are in use for 24 by seven duration. Therefore it becomes necessary to calibrate them at least thrice a year. Calibrating them for this period can help maintain the accuracy and keeps away any security hazard.
Concluding Lines
These are some of the different types of calibration that could be done for a measuring device. Calibration is important for every device, but it becomes necessary for measuring devices. The main purpose of these devices is to serve accuracy, which could be maintained by calibration.
