Abstract

A calibration and identification device for a multi-channel mine temperature sensor that can greatly improve the reliability and accuracy during use of the coal mine temperature sensor. The technical solution is: it is characterized by a constant temperature source, an auxiliary temperature source, a mercury thermometer, a digital communication acquisition and display system and a computer, wherein the constant temperature source is used to generate the liquid at the test temperature; the auxiliary temperature source is used to store the liquid at the desired temperature The mercury thermometer is used to calibrate the actual temperature source temperature according to the temperature range; the digital communication collection and display system is used to collect and display the electrical signal of the sensor; the computer is used to input, collect, convert, and judge the function and performance of the temperature sensor. The invention also discloses an identification method of the identification device.

Description

technical field [0001] The invention belongs to the field of calibration and identification devices and identification methods for temperature sensors used in mines, and particularly relates to a method that can greatly improve the reliability and accuracy of temperature sensors used in coal mines during use, so that the temperature sensors used in coal mines can The invention relates to a calibration identification device and identification method for a multi-channel mine temperature sensor whose function and performance are tested accurately and timely. Background technique [0002] With the regulation of coal mine safety requirements, the state has promulgated policies and regulations for various safety links in coal mines. The key parts of coal mines need to be equipped with temperature sensors for coal mines. However, due to the harsh environment of coal mines, it is necessary to regularly test and adjust the temperature sensors used. , and identification to ensure the ...
