Abstract

Resistance thermometers, as metrological instruments, are based on determining temperature through the physical quantity of resistance. These devices require periodic calibration to consistently ensure accuracy. The purpose of calibration is to compare the instrument’s readings with standard values and identify its errors. Traditional methods are often time- consuming and dependent on human factors. This article examines a modern method for calibrating two types of resistance thermometers used in technological processes. The calibration process employs an automatic analysis method using software. This method allows for automatic measurement of temperature during the process and obtaining its results. It is implemented using modern software, particularly the Lab VIEW program, which enables the calibration process to record temperature changes in real- time and track how it varies over time. This data can be stored in various file formats in the computer’s memory, linked to the time parameter. By employing the automatic calibration method for resistance thermometers, it becomes possible to prevent risks that may arise in production processes, reduce errors in temperature measurement, and improve overall accuracy.
