The altitude temperature test chamber is mainly used for testing the environmental adaptability and reliability of test pieces under the single or simultaneous effects of low pressure, high and low temperatures, condensation and frost, and for measuring the electrical performance parameters of the test pieces while they are powered on.
Our test chamber features outstanding performance and multiple functions, ensuring a stable testing environment under various extreme conditions. Whether it is for new product development or quality control, using a altitude temperature test chamber will save you time and costs, and enhance testing efficiency.
Application of altitude temperature test chamber
1、In aerospace, components and complete machines of aircraft, rockets, satellites and other spacecraft all need to be verified through this test chamber during the research and development stage to ensure their adaptability to harsh high-altitude environments and stable operation during actual flights.
2、Automotive Electronics: With the rise of autonomous driving technology, the reliability requirements for automotive electronic components are increasing day by day. Low-pressure test chambers can simulate the driving environment of vehicles in high-altitude areas and evaluate the performance stability of electronic components.
3、National Defense: Defense equipment often needs to adapt to harsh environments. High-altitude low-pressure test chambers have become an important means to verify their adaptability and reliability.
4、Consumer electronics: When consumer electronic products such as smart phones and tablet computers are used in high-altitude areas, they also need to pass low-pressure tests to ensure their normal operation and enhance user experience.
The working principle of the altitude temperature test chamber
1、Multiple sets of centrifugal fans are installed at the top inside the chamber. Through the air outlets, the fans evenly discharge air into the interior of the chamber to achieve gas circulation and balance the temperature inside the chamber. The data collected by the built-in temperature sensor in the chamber is transmitted to the temperature and humidity integrated controller (PLC). After editing and processing, the controller issues temperature adjustment instructions. It realizes temperature increase through the refrigeration system or heating system, condenser and evaporator, or adjusts the refrigeration solenoid valve to lower the temperature inside the chamber, so as to reach the required temperature.
2、The data collected by the built-in humidity sensor in the chamber is transmitted to the temperature and humidity integrated controller (PLC). After editing and processing, the controller issues humidity adjustment instructions. It increases the humidity inside the chamber by evaporating the water in the water tank through the heating tube in the humidification trough, or realizes dehumidification by adjusting the refrigeration solenoid valve, so as to reach the required humidity.
