A vacuum test chamber is a type of testing equipment capable of simulating specific environments. As an important type among them, the thermal vacuum test chamber is a comprehensive testing device that simulates high vacuum and alternating high and low temperature environments. It can simulate the real state of products in the usage environment and test the performance and reliability of products under high temperature, low temperature and vacuum conditions. It is mainly used for reliability testing and performance verification of products such as spacecraft components, satellite modules, precision electronic instruments, and optical devices. The thermal vacuum test chamber mainly simulates a high-temperature and high- vacuum environment through the coordinated action of a vacuum system and a heating/cooling system. The vacuum system expels the gas in the vacuum chamber through components such as vacuum pumps, gas condensers and pressure sensors, bringing the internal pressure close to a vacuum state. The heating system is usually composed of resistance wires, radiant heaters or high-frequency heaters, etc. The heating power and temperature are regulated by controlling the current and voltage of the heating elements. In practical operation, a high vacuum environment is formed by the combination of a main pump (such as a mechanical pump) and a molecular pump to evacuate the vacuum chamber. The heating system heats or cools the chamber through electric heating wires or liquid nitrogen, creating a uniform temperature field in the heat sinks of the chamber, simulating a space environment with both vacuum and a wide temperature range (such as -100℃ to 125℃).If you need more information about the models of our testing equipment.

Inner tank treatment: Stainless steel inner tank and treated to prevent steam and rust. Drip trough design: Hidden under the door, it is both effective and aesthetically pleasing. Noise reduction system: The control box adopts double-layer isolation, which can reduce the noise of the test chamber (by 59 to 68 decibels depending on the size of the compressor), and further noise reduction measures can also be taken according to the user's requirements. Air supply circulation system: It ensures that the parameters inside the test chamber can be precisely controlled even when the heat is slightly excessive. The powerful and sensitive exhaust system can quickly change the temperature of the air and samples inside the test chamber.If you need more information about the models of our testing equipment.

Vacuum environment simulation In the thermal vacuum test, the first step is to simulate the vacuum environment of space. When spacecraft operate in space, there is almost no air around them, meaning they are in a high vacuum state. To simulate this environment on the ground, a vacuum system is used, including vacuum pumps, gas condensers, and pressure sensors, etc. The gas inside the test chamber is evacuated to make the internal pressure approach the vacuum state. Usually, the vacuum requirement of the thermal vacuum test is better than 6.5x10^-3 Pa to ensure that the simulated vacuum environment is close enough to the real space environment.If you need more models about our test equipment, please reference our ： https://www.chamber-testing.com/ Temperature cycling simulation In space, spacecraft undergo significant temperature changes because they are exposed to solar radiation and cosmic darkness. The thermal vacuum test simulates these temperature cycles through heating systems and cooling systems. The heating system can use resistance wires, radiation heaters, or high-frequency heaters, etc., by controlling the current and voltage of the heating elements to regulate the temperature. The cooling system may use low-temperature media such as liquid ammonia. During the test, the spacecraft is heated to a high temperature (for example, +65°C) and cooled to a low temperature (for example, -35°C), and cycles between these extreme temperatures to test its performance under temperature changes.

Name: KL-233 LEVEL CONTROLLER Product description : The electronic level controller with 2 sensors will automate aquarium water top off. Since safety is our number one concern, we include two float switch sensors with our electronic water level controller. The first float switch sensor triggers the feed pump (sold separately) to maintain the desire water level. The second float switch sensor ensures dependability and offers overflow protection. Our water level controller can also be used to protect pump from running dry. It can be utilized in three ways : 1.In this mode the power supply will turn on if the water level in the sump is low AND there is enough water in the storage tank. The power supply will turn off if the water level in the sump is high AND there is not enough water in the storage tank. (View Operation diagram, MODE A-1) With this set up the power supply will turn on as soon as the water level in the sump drops below the set level. The power supply will turn off if the water level in the sump is high the set level. (View Operation diagram, MODE A-2) 2. The power supply will turn on when the level falls below the minimal level of float sensor1 and will turn off when water rises the set point of the flow sensor1. The float sensor2 acts as a backup sensor in the event the float sensor1 is stuck. The level controller will not allow the power supply to turn on if the water level in the sump reaches the maximum level of float sensor2. (view Operation diagram, MODE B) 3. Immerse the sensor1 and sensor2 in the measured solution(sump).With this set up the power supply will turn on when both sensors detected that the water level is below the minimum level and stop only when the water rises the maximum level of both sensor. (View Operation diagram, MODE C)
