Rapid temperature measurement multi-point thermocouple

Abstract

The invention discloses a rapid temperature measurement multi-point thermocouple, and relates to the technical field of thermocouples. The rapid temperature measurement multi-point thermocouple comprises a multi-point thermocouple body, an adsorption mechanism is arranged on the lower surface of the upper side of the multi-point thermocouple body, a blocking mechanism is arranged on the outer wall of the multi-point thermocouple body, and the blocking mechanism is arranged on the side wall of the middle of the multi-point thermocouple body. When the rapid temperature measurement multi-point thermocouple is used, the multi-point thermocouple body is inserted into an object to be measured, the bottom block is blocked and stopped by the object to be measured, and the top block descends to extrude out air in the connecting leather, so that the push block is pushed to move to extrude out air on the lower side in the air cavity, and the suction cup is in contact with the object to be measured; and the expansion ring clamps the interior of the clamping groove, so that the situation that the suction cup is separated from the measured object due to the fact that the first spring rebounds is avoided.

Description

technical field [0001] The invention relates to the technical field of thermocouples, in particular to a fast temperature measuring multi-point thermocouple. Background technique [0002] Thermocouple (thermocouple) is a temperature measuring element commonly used 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 appearance of couples is 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 used in conjunction with display instruments, recording instruments and electronic regulators , multi-point thermocouple is suitable for the production site where the temperature gradient is not significant, a...

Problems solved by technology

[0003] When performing temporary temperature measurement of the target to be measured, because the temperature of the target to be measured may be relatively high, and the temporary temperature measurement window may not be convenient to fix, so it needs to be stabilized by hand, which causes the problem of hot and dry hands, so a kind of The device can achieve auxiliary stability when measuring temperature
