The invention discloses a transverse thermal resistor comprising a junction box, an adjusting frame and a temperature measuring head. The adjusting frame is connected with the junction box. The adjusting frame includes a column which is internally provided with a first through cavity. A mounting plate is mounted on the column, the mounting plate is provided with a first threaded hole and a second threaded hole, and a first adjusting screw and a second adjusting screw are respectively mounted in the first threaded hole and the second threaded hole. The first adjusting screw and the second adjusting screw are respectively provided with a second through cavity and a third through cavity inside. The temperature measuring head is an elastic band body, and the first adjusting screw, the second adjusting screw and the column are connected with the temperature measuring head. The temperature measuring head includes an elastic metal sheet, a temperature measuring assembly embedded into the elastic metal sheet, and a first lead and a second lead respectively connected with the two ends of a resistor assembly. According to the invention, the temperature measuring head contacts a measured object in a coating manner during temperature measurement, which can increase the response speed of the temperature measuring element, improve the sensitivity and accuracy of temperature measurement and improve the reliability of temperature measurement.
Description
technical field [0001] The invention relates to the technical field of thermal resistors, in particular to an end face thermal resistor. Background technique [0002] The thermal resistance is the most commonly used temperature detector in the middle and low temperature area. The thermal resistance temperature measurement is based on the characteristic that the resistance value of the metal conductor increases with the increase of temperature to measure the temperature. [0003] At present, due to the limitation of the shape and structure of the traditional thermal resistance products, when measuring the measured object with an arc structure, only one point is in contact with it, which makes the temperature measurement reliability poor, resulting in slow response to the measured temperature and inconsistent measurement results. Accurate, unable to meet the requirements of users who require more precise measurement results. Contents of the invention [0004] Based on the t...
