Description

Technical Field

[0001] The invention belongs to the technical field of temperature measuring devices, and in particular relates to a multifunctional temperature measuring device and a temperature measuring method thereof. Background Art

[0002] At present, most infrared thermal imagers are used to measure temperature in an open environment. There is no closed environment. The infrared thermal imager is also fixed on a simple bracket. The fixture is also clamped with a simple clamp. The focus is adjusted by moving the entire fixture. The focus is inaccurate and there is strong external interference. Infrared thermal imagers require a closed environment for temperature measurement. The external environment has a greater impact on it. In addition, the problem of inaccurate focus adjustment of infrared thermal imagers requires a device with high adjustment accuracy and a closed environment. At present, infrared thermal imagers can only measure temperature on one side. Testing requires a device that can measure temperature on two or more sides.

[0003] Thermocouple temperature measurement has the problem of difficulty in fixing the thermocouple and the measured point. The thermocouple and the measured object need a very small fixing force to achieve accurate thermocouple temperature measurement, but in actual operation it is difficult to control whether the thermocouple and the measured object are tightly fixed. At present, thermocouple temperature measurement can only achieve single-point temperature measurement, and it is necessary to develop a device that can easily achieve multi-point thermocouple temperature measurement.

[0004] In view of the above-mentioned difficulties in thermocouple temperature measurement and the difficulty in achieving multi-point temperature measurement, there is an urgent need to design a device that provides a very small fixing force between the thermocouple and the object being measured, so that the temperature measurement is accurate and multi-point temperature measurement can be achieved.
