A temperature measuring device based on organic reversible temperature sensing materials

Abstract

The invention proposes a temperature measuring device based on an organic reversible temperature-sensing material, including a heat conduction unit and a temperature-sensing discoloration unit. It is on the heat conduction unit, and changes color according to the temperature change of the heat conduction unit; it also includes a transparent heat insulation unit, which is covered on the outside of the heat conduction unit and the thermochromic unit, and the heat transfer end part of the heat conduction unit is separated from the transparent heat insulation unit The color change of the temperature-sensitive color-changing unit can be revealed from the transparent heat-insulating unit; the temperature measuring device is realized based on organic reversible temperature-sensing materials, and the basic principle of engineering heat transfer is used to make the temperature of the heat source correspond to the temperature on the temperature measuring device. The scale position reflects that the operator can easily obtain the reference value of the preheating temperature through the discoloration of the temperature-sensitive material, which provides a convenient and accurate way for the temperature detection of the heat treatment before welding.

Description

technical field [0001] The invention relates to a temperature detection instrument, in particular to a temperature measurement device based on an organic reversible temperature-sensing material. Background technique [0002] With the concept of sustainable development gradually gaining popularity, offshore wind power has been paid more and more attention as a green production capacity equipment. However, since most offshore welding structures are welded with large thick plates and require high-altitude operations, preheating before welding is required in order to reduce welding defects. Welders often use flame preheating, and the preheating temperature depends only on the worker's operating experience. Traditional contact thermistor temperature measurement (except for special high temperature thermistors, most thermistors are only suitable for 0 ~ 150 ℃) and thermocouple temperature measurement methods (0 ~ 1800 ℃) need to destroy the surface of the heat source to RTDs or t...

Problems solved by technology

[0004] When preheating its equipment, it was found that the current temperature measurement methods and instruments are not suitable for not destroying the surface of the heat source, displaying the temperature change of the area in real time and showing obvious phenomena at the critical temperature, and being easy to operate and recyclable. It is necessary to design a temperature measuring device to overcome the above defects
