Abstract

The invention provides a length-adjustable high-precision thermocouple comprising a junction box, a protective tube and a thermal electrode, the protective tube comprising a first tube body, a second tube body and a third tube body, the thermal electrode comprising a first conductor, a second conductor, a first helical wire, and a second helical wire. Only the third tube body is rotated when the length of the thermocouple is required to be adjusted. The first conductor and the second conductor are connected with binding posts in the junction box through the first helical wire and the second helical wire, respectively. The first conductor and the second conductor are sleeved with a first insulation protection tube and a second insulation protection tube respectively so as to ensure the temperature measurement performance of the first conductor and the second conductor. Through the cooperation of the first tube body, the second tube body, the third tube body, the first conductor and the second conductor, the length-adjustable high-precision thermocouple measures the temperature of temperature measurement areas at different heights, is simple in operation, convenient to use, and high in temperature measurement precision.

Description

technical field [0001] The invention relates to the technical field of thermocouples, in particular to an adjustable-length high-precision thermocouple. 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 measurement point. When there are multipl...
