Kalibraatoreid

Kalibraatoreid, known in English as calibrators, are devices or standards used to adjust and verify the accuracy of measuring instruments. They ensure that a measuring device is providing correct readings by comparing its output to a known, accurate reference value. This process, calibration, is crucial in various fields, including science, engineering, manufacturing, and healthcare, to maintain quality control, ensure safety, and comply with regulations.

There are different types of calibrators depending on the quantity being measured. For example, pressure calibrators are used to check the accuracy of pressure gauges and transmitters. Temperature calibrators are used for thermometers and temperature sensors. Electrical calibrators can verify the readings of multimeters, oscilloscopes, and other electrical test equipment. Dimensional calibrators are used for tools like calipers and micrometers.

The principle of operation for a calibrator typically involves generating a precise and traceable reference value. This reference value is then applied to the instrument under test. The instrument's reading is compared to the calibrator's reference value, and any deviation is noted. If the deviation exceeds acceptable tolerances, the instrument is adjusted or deemed faulty. Calibration is often performed at regular intervals or after specific events, such as maintenance or repairs, to ensure ongoing accuracy. Traceability to national or international standards is a key aspect of reliable calibration.
