Problems solved by technology
In the prior art, a thermocouple with an appropriate length is usually selected according to the condition of the temperature measurement space and the position of the temperature measurement point. When there are multiple temperature measurement points in the same temperature measurement space, it is often necessary to add multiple thermocouples for measurement. temperature or during the temperature measurement process to replace the thermocouple, the operation is inconvenient and needs to be improved

The invention provides a multi-segment temperature-measuring length-adjustable thermocouple. The multi-segment temperature-measuring length-adjustable thermocouple comprises a terminal box and a plurality of thermocouples having different lengths. A first protection tube comprises a first tube body, a second tube body, and a first bellows used for connecting the first tube body and the second tube body. A second protection tube comprises a third tube body, a fourth tube body, and a second bellows used for connecting the third tube body and the fourth tube body. The length of the first protection tube and the length of the second protection tube are adjusted by folding and unfolding the first bellows and the second bellows, and therefore the length of the thermocouple is adjusted. The first protection tube and the second protection tube are bent by bending the first bellows and the second bellows, and then the thermocouple is bent to be adapted to use requirements of different places. The multi-segment temperature-measuring length-adjustable thermocouple is used for measuring temperatures of different temperature measuring points in the same temperature measuring space, and the lengths of the various thermocouples are adjusted, and the thermocouples are bendable to be adapted to the different temperature measuring places, and in addition, the multi-segment temperature-measuring length-adjustable thermocouple has advantages of simple structure, accurate temperature measurement, and diverse functions.
Description
technical field [0001] The invention relates to the technical field of thermocouples, in particular to a multi-section thermocouple with adjustable length for temperature measurement. Background technique [0002] A thermocouple is a temperature measuring instrument manufactured according to the Seebeck effect, that is, the principle of generating a thermoelectric potential when there is a temperature difference between the two ends by using two homogeneous conductors of different compositions to form a circuit. Because of its simple structure, wide applicable temperature range, high measurement accuracy, convenient use, strong ability to withstand heat and mechanical shock, and fast response speed, it has become one of the most commonly used temperature detection components in industry. In the prior art, a thermocouple with an appropriate length is usually selected according to the condition of the temperature measurement space and the position of the temperature measuremen...
