[0002] A temperature sensor refers to a sensor that can sense temperature and convert it into an available output signal. The temperature sensor is the core part of a temperature measuring instrument and is widely used in various electronic components or various industries.
[0003] In order to ensure the safety of gas meter use, it is necessary to monitor the temperature of the gas meter. Usually, a temperature sensor is provided on the gas meter. Therefore, the detection sensitivity and accuracy of the temperature sensor are crucial. Usually, when the temperature sensor is produced, it is necessary to measure the accuracy of the temperature detected by the temperature sensor.
[0004] In most measuring devices, usually the temperature sensor is connected to a connection line and placed in a closed and stable temperature environment. The data measured by the reference temperature sensor is compared with the ambient temperature to judge the detection effect of the temperature sensor. However, when manufacturing a closed environment, it is easy to squeeze and deform the connection line, damage the wire, and the position of the wire in the closed environment is likely to form a gap, affecting the temperature in the closed space and resulting in inaccurate detection results.
