Industrial devices lose accuracy over time. Thermometers, pressure gauges, and other devices are subject to a variety of stresses – mechanical, chemical, as well as thermal, which result in wear and tear hamper their performance. In order to ensure reliable readings, regular calibration of these devices is necessary. This includes tune-ups, which not only prolong a device’s lifetime, but help get the most accurate readings from better calibration. When should you consider calibrating a measurement device depends on a variety of factors:
Operating conditions of the instrument - Does the instrument regularly undergo large fluctuations in pressure or temperature? How much has it been exposed to shock, pulsation, vibration, and other mechanical stresses? All these things determine the operating condition of the device. Frequent calibrations can mitigate the effects.
Device’s value in the particular application - Is the instrument being used in a critical process? Will plant or product safety be compromised by even small deviations in accuracy? Will the entire process suffer if the thermometer, gauge, or indicator does not perform within certain limits? These are some of the questions that need to be asked before scheduling a calibration.
Although when you should consider unerring thermometer calibration service depends on the particular conditions and needs of the application, a calibration check and re-certification - once every 12 months is ideal. Accuracy verification and calibration can be performed during:
Preventive maintenance
scheduled shutdowns
An annual audit
Downtime and expenses associated with calibration are negligible compared to the errors that could possibly lead to batch contamination, tank leaks, plant explosions, and so forth.
