Preparation method of heating type thermocouple liquid level measurement sensor

Abstract

The invention relates to a preparation method of a heating type thermocouple liquid level measurement sensor. According to the preparation method of the heating type thermocouple liquid level measurement sensor, prepared heating elements and prepared armored cables are assembled together and fully sealed so that the heating type thermocouple liquid level measurement sensor can be obtained. The heating type thermocouple liquid level measurement sensor prepared through the method has the advantages of being capable of accurately judging a liquid-gas (vapor) interface under the conditions of high temperature and high pressure, good in reproducibility and high in resolution, capable of meeting requirements of an overload test, capable of accurately judging the liquid-gas (vapor) interface under severe environments of high temperature and high pressure, simple in process and good in uniformity of products.

Description

technical field

[0001] The invention relates to a preparation method of a sensor, in particular to a preparation method of a heating type thermocouple liquid level measurement sensor. Background technique

[0002] At present, the water level measurement in the pressure vessel is often measured by the armored cable sensor, which has the following disadvantages: 1. Conventional armored cables (such as armored thermocouples) cannot distinguish the gas-liquid interface; 2. Conventional armored cables Cables (such as armored heaters) also cannot resolve the gas-liquid interface and cannot be used for level measurement. The existing heating thermocouple liquid level measurement sensor adopts the products produced abroad, which has high cost and difficult maintenance, which seriously restricts the development of liquid level measurement technology in our country. Therefore, find a production process so that the obtained heating thermocouple liquid level measurement sensor can meet...
