DEVELOPMENT OF A CALIBRATION TECHNIQUE FOR DETERMINING THE METROLOGICAL CHARACTERISTICS OF A CONSTRUCTED ELECTRONIC THERMOMETER
Keywords:
electronic thermometer, circuit diagram, printed circuit board, calibration, calibration procedure, absolute error, type B uncertaintyAbstract
In this work, a schematic diagram of an electronic thermometer has been developed, which can be used to measure the temperature of the air outside and indoors. This thermometer has a temperature range from -30°C to +40°C. According to the developed scheme, a printed circuit board is made, a program is written. A calibration technique for an electronic thermometer is proposed. Measurements were carried out, according to the results of which the absolute error and uncertainty of type B were determined. The calculation results show that the absolute error of the constructed thermometer is no more than 0.2°C.
