Temperature sensors are the core part of temperature measuring instruments and come in many varieties. According to the measurement method, they can be divided into two categories: contact and non-contact. According to the sensor material and electronic component characteristics, they can be divided into thermal resistors and thermocouples. When it is necessary to detect the temperature of the pipeline surface, a pipeline surface temperature sensor is needed. Therefore, a heat-insulating pipeline surface temperature sensor is particularly needed.
[0003] However, existing temperature sensors are generally square or round, and are in surface or point contact with the pipe surface, making heat conduction difficult and having low sensitivity. As a result, heat dissipation is fast, and the temperature cannot be concentrated and transmitted to the temperature sensing core, resulting in low sensitivity, which affects the use of detection.
