What is a Calibrator? Definition, Types, and Purpose

A calibrator is a device or system that is used to adjust the accuracy of another device or system. The purpose of a calibrator is to provide a known reference point against which the performance of the device or system being calibrated can be measured and adjusted.

Calibration is the process of comparing the output of a device or system to a known standard or reference, and adjusting the device or system to match the standard. This process is often necessary because manufacturing tolerances and other factors can cause devices or systems to deviate from their intended performance specifications.

There are many different types of calibrators, including:

1. Temperature calibrators: These devices are used to adjust the temperature of a thermometer or other temperature-measuring device to ensure that it is accurate.
2. Pressure calibrators: These devices are used to adjust the pressure reading of a pressure gauge or other pressure-measuring device to ensure that it is accurate.
3. Flow calibrators: These devices are used to adjust the flow rate of a flow meter or other flow-measuring device to ensure that it is accurate.
4. Electrical calibrators: These devices are used to adjust the output of an electrical device, such as a voltage or current source, to ensure that it is accurate.
5. Time calibrators: These devices are used to adjust the timekeeping of a clock or other time-measuring device to ensure that it is accurate.

Overall, the purpose of a calibrator is to provide a known reference point against which the performance of another device or system can be measured and adjusted to ensure accuracy.
