Abstract

The invention discloses a novel temperature measurement thermal resistor, including a metal protective tube, a junction box and an elastic connection column. One end of the metal protective tube is connected with one end of the junction box through the elastic connection column, the metal protective tube is internally provided with a leading-out wire and a temperature measurement element, one end of the leading-out wire is connected with the temperature measurement element, the other end stretches out of the junction box, the outer side end of the junction box is fixedly provided with a sealing gasket, and the leading-out wire in the metal protective tube is of an S-shaped structure. The novel temperature measurement thermal resistor provided by the invention is simple in structure, adopts the S-shaped leading-out wire, can enhance buffering performance, improve measurement accuracy, and prolong the service life of the temperature measurement element; and in addition, the adopted sealing gasket can reduce heat loss, thereby further improving a temperature measurement effect.

Description

technical field

[0001] The invention relates to the technical field of temperature measuring resistors, in particular to a novel temperature measuring thermal resistor. Background technique

[0002] Thermal resistance is a temperature measuring device that uses the physical phenomenon that the resistivity of a conductor changes with temperature to measure temperature. It has the characteristics of high sensitivity, stability, good interchangeability and high precision. Thermal resistance is usually used in conjunction with display instruments, recording instruments and electronic regulators. Thermal resistance can directly measure the temperature of liquid, vapor and gas medium and solid surface in the range from -200℃ to +600℃ in various production processes.

[0003] Although the temperature measuring thermal resistance in the prior art can measure temperature, its buffer performance and sealing performance are poor during the measurement process, which affects the measur...
