Abstract
The utility model discloses a thermocouple temperature sensor with high response speed. The thermocouple temperature sensor is provided with a protection casing (1), wherein an electrode (2) and an insulated filling material (3) which are arranged in parallel are arranged in the protection casing (1), a packaging layer (4) is arranged at the front end of the protection casing (1), the electrode (2) passes through the packaging layer (4), and a combined point (5) of the electrode (2) is positioned outside the packaging layer (4). According to the thermocouple temperature sensor disclosed by the utility model, the influence of heat dissipation of the packaging layer on detection is avoided, high temperature generated when certain matter in a detected object is vaporized can be directly monitored, the response speed is high, and the time point of generating vaporization can be instantly captured, therefore the temperature (namely vaporization temperature) of the detected object at the moment of vaporization occurrence is determined, and the vaporized matter is determined through the vaporization temperature, and the detection precision is remarkably improved.
Description
Technical field
The utility model discloses a kind of thermocouple sensor, especially a kind of fast thermocouple temperature sensor of response speed that improves accuracy of detection.
Background technology
At present, the temperature detection technology has been applied to the constituent analysis of organic mixtures such as oil.Concrete grammar is that testee is placed the heating container cascade raising temperature, and the temperature sensor intubate of temperature-sensing elements such as interior dress RTD is placed testee, detects the temperature of testee in real time; Simultaneously the hot junction of thermocouple temperature sensor is placed the top of testee, monitor hot junction environment temperature on every side in real time.Vapourizing temperature difference because of different material; So the heterogeneity of testee in the heat temperature raising process, can be vaporized in different temperature points (time point), produces huge energy (high temperature); The hot junction of thermocouple temperature sensor then should capture the high temperature that vaporization takes place in moment; Thereby confirm to take place the time point of vaporization, and confirm to take place the vaporization temperature (being vapourizing temperature) of testee constantly, confirm to take place the material of vaporization through vapourizing temperature.Existing thermocouple temperature sensor is provided with protective casing, and the electrode and the insulation filling material that laterally arrange are arranged in protective casing, and the protective casing front end has the Metal Packaging layer, and the binding site of parallel pole (hot junction) is welded on the inwall of Metal Packaging layer.The high temperature that produces when owing to material vaporization taking place can shed along the Metal Packaging layer; So the temperature of existing thermocouple sensor hot junction monitoring is the temperature after the vaporization heat radiation; Therefore lack, when temperature is relatively low, the omission phenomenon will occur when vaporization time, reduced accuracy of detection.
Summary of the invention
The utility model is in order to solve the above-mentioned technical matters of existing in prior technology, a kind of fast thermocouple temperature sensor of response speed that improves accuracy of detection to be provided.
The technical solution of the utility model is: the thermocouple temperature sensor that a kind of response speed is fast; Protective casing is arranged; The electrode and the insulation filling material that laterally arrange are arranged in protective casing; The protective casing front end has encapsulated layer, and said electrode passes encapsulated layer, and the binding site of electrode is positioned at outside the encapsulated layer.
The electrode binding site (hot junction) of the utility model places outside the encapsulated layer; Avoid can directly monitoring the high temperature that is produced when certain material is vaporized in the testee because of the influence of encapsulated layer heat radiation to detecting, response speed is fast; Capture the time point that vaporization takes place in moment; Thereby confirm to take place the vaporization temperature (being vapourizing temperature) of testee constantly, through the definite material that vaporization takes place of vapourizing temperature, accuracy of detection obviously improves.
