Description

Technical Field

[0001] The utility model relates to the technical field of temperature sensors, in particular to a heat-insulating temperature sensor. Background Technique

[0002] A temperature sensor refers to a sensor that can sense temperature and convert it into an available output signal. Generally, various currently used temperature sensors are placed with the sensor exposed, and the outer shell of the sensor is fixedly physically contacted with the surface of the object to be detected. By synchronizing the temperature with the object to be detected, the resistance value change caused by the temperature change of the sensor itself forms a current or voltage change in the circuit to obtain temperature data. However, in actual use of existing temperature sensors, during the temperature measurement process, the heat dissipation of the sensor itself and the heat dissipation during the heat conduction process are relatively serious, which will affect the accuracy of the measurement results. For example, in the outdoor exposed environment of an oil storage tank, it is very difficult to achieve temperature synchronization in the heat conduction between the sensor body and the tank to be measured, thus affecting the accuracy of the detected temperature.

[0003] As in the prior art, the Chinese utility model content with the publication number: CN209945563U discloses an adsorption type temperature sensor, including a base, a high-temperature resistant magnet, a temperature measurement device, a heat insulation device, a sealing device, a heat conducting glue, and a shock absorption spring. The high-temperature resistant magnet is fixed on the chassis of the base. A through temperature measurement groove is opened inside the base. The temperature measurement device is arranged inside the base. The temperature measurement device and the base are connected and fixed through the shock absorption spring. A heat insulation device is sleeved outside the base and the high-temperature resistant magnet. The sealing device is threadedly connected with the base. The sealing device and the base encapsulate the high-temperature resistant magnet and the heat insulation device. The tail of the temperature measurement device passes through the sealing device, and the heat conducting glue is evenly coated on the bottom of the base; the adsorption is realized by the combined action of the heat conducting glue and the high-temperature resistant magnet, which is more stable. The heat insulation device is used to prevent heat dissipation during the heat conduction process. After the temperature of the surface of the object to be measured exceeds a certain limit, the high-temperature resistant magnet demagnetizes, and the device can still be adsorbed and fixed on the surface of the object to be measured.

[0004] It can be known from the above that in the prior art, it is very difficult to achieve temperature synchronization in the heat conduction between the sensor body and the tank to be measured, which easily affects the accuracy of the detected temperature. Therefore, we need to propose a heat-insulating temperature sensor. Utility Model Content
