MEASURING UNIT FOR TEMPERATURE MEASUREMENT Russian patent published in 2021 - IPC G01K7/02 G01K7/13 G09B23/06 

FIELD: educational equipment.

SUBSTANCE: invention relates to the field of educational equipment and relates to the design of measuring modules, for example, temperature based on the use of chromel-alumel thermocouples used in teaching aids systems, including when carrying out laboratory work with a measurement control system in secondary and higher educational institutions, as well as conducting research, it can be used in the study of physics, acoustics, mechanics, thermodynamics, electronics and other academic disciplines. And it is a measuring module containing a split case with fixing elements, a printed circuit board with a microcontroller located in it, a hole in the case with a sensor located in it connected to the microcontroller, and another hole in the case with a USB connector located in it connected to the microcontroller, in which the housing is equipped with an additional hole, and the sensor is made on the basis of a thermocouple sensitive element located at the end of a piece of thermocouple wire enclosed in a heat-resistant insulating sheath. In this case, the printed circuit board is equipped with a correcting element for compensating the cold junction temperature and an amplifier located between the sensor and the microcontroller, and the measuring module is equipped with an analog (IDC) connector for connection to an open architecture board located in an additional hole in the housing.

EFFECT: increasing the versatility and multifunctionality of the measuring module with the ability to conduct various demonstrations and change the conditions for conducting experiments and experiments when visualizing the results obtained.
