Problems solved by technology

[0003] In the application of high temperature measurement, during the use of the thermocouple with the exposed end outside, the hot end of the temperature measurement is easy to be grounded or swings in a high temperature state, causing the temperature measurement point to contact the metal wall, resulting in electromotive force fluctuations, computer terminal system crashes, and system alarms , temperature jump and other unknown reasons lead to product quality control out of control, so we propose a structure to avoid thermocouple hot end grounding and its use method

Abstract

The invention discloses a thermocouple hot end grounding prevention structure and a use method thereof.The thermocouple hot end grounding prevention structure comprises a thermocouple body, two thermocouple electrodes are arranged in the thermocouple body, an insulating protective sleeve is arranged on the outer sides of the two thermocouple electrodes, an insulator is arranged between the two thermocouple electrodes, and a quick plug is arranged at one end of the thermocouple body; the other end of the thermocouple body is provided with a temperature measurement hot end sleeve head. The temperature measuring end of the thermocouple is provided with the temperature measuring hot end sleeve head made of the high-temperature-resistant material, so that electromotive force fluctuation caused by contact between the thermocouple and a metal wall due to grounding of a temperature measuring end point or swinging in a high-temperature state during use of the thermocouple is avoided, and inaccurate temperature display jitter is avoided.

Description

technical field [0001] The invention relates to the technical field of thermocouples, in particular to a structure for avoiding grounding of thermocouple hot ends and a method for using the same. Background technique [0002] Thermocouple is a commonly used temperature measuring element in temperature measuring instruments. It directly measures the temperature, and converts the temperature signal into a thermal electromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument (secondary instrument). The shapes of various thermocouples are often very different due to needs, but their basic structures are roughly the same, usually composed of main parts such as thermal electrodes, insulating sleeve protection tubes, and junction boxes, and are usually associated with display instruments, recording instruments, and electronic regulators. Supporting use with the device; [0003] In the application of high temperature measur...
