Abstract

The invention discloses a thermocouple temperature sensor with a fast response speed, comprising a protective casing (1), wherein electrodes (2) which are disposed in parallel and an insulated filling material (3) are disposed in the protective casing (1); a packaging layer (4) is disposed at the front end of the protective casing (1); and the electrodes (2) penetrate through the packaging layer (4), and the combination point of the electrodes (2) is arranged outside the packaging layer (4). The influence on detection due to the heat dissipation of the packaging layer is avoided; the high temperature generated during vaporization for some substance in a detected object can be directly monitored; response speed is fast, and the time point of the occurrence of vaporization is captured instantaneously, thus determining the temperature (i.e., vaporization temperature) of the detected object at the time of the occurrence of vaporization; and detection accuracy is obviously improved by determining the vaporized substance via vaporization temperature.

Description

technical field

[0001] The invention discloses a thermocouple sensor, in particular a thermocouple temperature sensor with fast response speed which can improve detection accuracy. Background technique

[0002] At present, temperature detection technology has been applied to the composition analysis of organic mixtures such as petroleum. The specific method is to place the measured object in a heating container to raise the temperature step by step, place the temperature sensor intubation tube with built-in platinum resistance and other temperature sensing elements in the measured object, and detect the temperature of the measured object in real time; at the same time, place the thermocouple temperature sensor The hot end is placed above the object to be measured, and the ambient temperature around the hot end is monitored in real time. Due to the different vaporization temperatures of different substances, different components of the measured object will vaporize at differ...
