Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of sensor detection, and in particular to a temperature sensor waterproof detection device. Background Art
[0002] With the advancement of technology and the development of industrial automation, temperature sensors are increasingly used in various complex environments. However, many applications involve high humidity or direct contact with water, such as underwater detection, weather stations, and industrial process control. Therefore, ensuring that temperature sensors have good waterproof performance is crucial. Traditional waterproof testing methods exist.
[0003] Temperature sensors are mainly divided into RTD temperature sensors, thermocouple temperature sensors, and thermistor temperature sensors. The following are the key points for waterproof testing of different temperature sensors: RTD temperature sensors are typically tested for water resistance using an immersion test, where the sensor is fully or partially immersed in water to observe whether its resistance changes. Long-term stability testing is also required to evaluate the sensor's performance in underwater environments. Thermocouple temperature sensors are typically tested for water resistance using a pressure test method. This involves injecting water at a certain pressure into the test chamber to simulate water pressure environments at different depths. During the test, the thermocouple's output voltage must be observed to determine if it is stable to determine its water resistance. Thermistor temperature sensor waterproof test can also be carried out by immersion test or spray test. During the test, it is necessary to pay close attention to the change of resistance value and record the test data for subsequent analysis. In summary, different types of temperature sensors use different waterproof detection methods. Conventional temperature sensor waterproof detection equipment in the existing technology has a single method and cannot simulate the actual usage environment, resulting in poor detection applicability and accuracy. Therefore, we propose a temperature sensor waterproof detection device to solve this problem. Summary of the Invention

The vertical tube 801 drives the rack 804 to move synchronously through the sleeve plate 803. The rack 804 drives the rotating shaft 901 to rotate by engaging with the transmission gear 902. The rotating shaft 901 drives the rotating seat and multiple inclined rods 903 to rotate, thereby driving the connecting plate to perform a circular motion. The connecting plate and the counterweight plate 905 are thrown outward under the action of centrifugal force and move to the right along the inclined rod 903. At the same time, the connecting plate drives the connecting rod 904 and the connecting frame 906 to rotate. The connecting frame 907 moves to the right, and the connecting frame 907 drives the connecting shaft 908 and the connecting cylinder 914 to move to the right, and compresses the return spring 911. When the air pressure in the casing 1 increases instantaneously, the rotating shaft 901 rotates faster, causing the connecting cylinder 914 to contact the touch button 912. The touch button 912 sends control information to the control panel 10. At the same time, the control panel 10 controls the boost pump 13 to stop working and controls the cylinder 1102 to contract, so as to relieve the pressure on the casing 1, avoid the air pressure rising too quickly, resulting in inaccurate detection results, and avoid damage to the temperature sensor.
