Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that existing test equipment cannot carry out simulation tests on temperature sensors during actual use. Some temperature sensors need to perform detection work in harsh conditions. In actual use, the reliability will be greatly reduced, resulting in the problem that the collected data is not accurate enough, and a high-reliability temperature sensor proposed

Abstract

The invention discloses a high-reliability temperature sensor, and belongs to the technical field of sensors. The high-reliability temperature sensor comprises a test box and an equipment box, two symmetrical fixing rods are fixedly connected in the test box, a moving plate is slidably connected to the fixing rods, the fixing rods are sleeved with return springs, the two ends of the return springs are fixedly connected with the test box and the moving plate respectively, the upper end of the moving plate is fixedly connected with a placing frame. The shock resistance of the temperature sensor body can be tested through the arrangement of the telescopic mechanism, and the moisture resistance of the temperature sensor body can be tested through the arrangement of a water vapor storage box, a gas conveying mechanism, a gas conveying pipe and a gas spraying head. By performing various simulation tests on the temperature sensor body, whether the quality of the temperature sensor body is qualified and whether the acquired data is accurate can be detected, so that the high reliability of the temperature sensor body in actual use is effectively improved.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a high-reliability temperature sensor. Background technique [0002] A sensor is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, and display. , recording and control requirements. [0003] The temperature sensor refers to a sensor that can sense temperature and convert it into a usable output signal. Temperature sensors are the core part of temperature measuring instruments. There are many varieties. They can be divided into two categories: contact type and non-contact type according to the measurement method. According to the characteristics of sensor materials and electronic components, they can be divided into thermal resistance and thermocouple. [0004] Howev...
