Temperature sensor

Abstract

The invention discloses a temperature sensor. The sensor comprises a housing, a contact pin and a heat-transfer paste. The heat-transfer paste is arranged at the bottom of the housing. A sensor element is arranged in the heat-transfer paste. The sensor element is provided thereon with the contact pin. The upper end of the contact pin is connected with a connection line. The upper end of the heat-transfer paste is provided with a shielding gas. A vacuum feedthrough is suspended at the upper end of the shielding gas. The inner top end of the housing is provided with a temperature inductor. The upper surface of the temperature inductor is provided with a temperature display. The temperature sensor and an alarm are connected. The temperature inductor is provided with a controller. The controller is connected with a vent cover via a circuit. The temperature sensor and the alarm are connected, so that the temperature exceeding phenomenon is warned. Therefore, the sensor is prevented from being damaged. The temperature display can visually display the temperature so as to prompt a user of the high temperature phenomenon. The temperature inductor is provided with the controller, and the vent cover is controlled by the temperature controller to be opened during the high-temperature warning process. Therefore, the temperature sensor is physically cooled.

Description

technical field [0001] The invention relates to a temperature sensor and belongs to the field of sensors. Background technique [0002] Generally, many temperature sensors are mounted inside an automobile or the like in order to detect the temperature of each part. These temperature sensors measure temperature by detecting heat transmitted from an automobile device or the like as a measurement object by a thermistor element unit. However, the temperature sensor can easily cause the temperature to reach the upper limit of the set value range. If it continues to rise, the volume of the filling medium in the sensor cannot continue to expand, and the rising internal pressure will damage the sensor. Therefore, a new technology needs to be sought to solve this problem. Contents of the invention [0003] The purpose of the present invention is to provide a novel temperature sensor. [0004] In order to achieve the above object, the technical solution adopted in the present inv...
