The Explosion- proof Structure of High Low Temperature Humidity Test Chamber
1. Box Reinforcement
2. Security Door
In addition to the door of the test box with the observation window, it should also be equipped with an explosion-proof chain and a limit switch for opening the door. First of all, the explosion-proof chain can prevent the door of the test box from flying out. It also acts as a buffer and protection. Secondly, the limit switch for door opening detection ensures that the test box is not in operation when the door is opened. The test chamber must be operated when the protective door is closed and the limit switch is closed.
3. Pressure Relief Door
Pressure relief doors are very important. The pressure relief door will act when the internal pressure in the tank rises sharply, releasing the pressure inside the tank. Therefore, the pressure relief door needs to be relieved to the rear side or the top side of the tank, and it is not allowed to release pressure to the lateral and bottom of the tank to prevent injury.

The Electrical Design of Explision-proof Temperatrue Humidity Test Chamber
1. Temperature Anomaly Detection
It is equipped with a temperature sensor that can be moved anywhere in the box. The sensor can be used to detect the surface temperature of the sample. When the surface temperature of the sample is abnormal and higher than the preset temperature, the red alarm light of the device and the overheated light in the box are illuminated at the same time. And the device stops running and the sample power is turned off by the test power terminal.
2. Automatic Jet Fire Protection
When a fire or explosion occurs, the temperature in the high and low temperature damp heat test chamber will rise sharply. This abnormal temperature change can be detected by a dedicated temperature sensor. What’s more, the equipment will transmit this abnormal temperature signal to the test chamber control system. The system will inject CO2 by opening the electric valve to ensure safety.
3. Emergency Stop Switch
The operator should immediately press the emergency stop switch if there is an abnormality in the box. Ensure that the equipment stops the cabinet. The secondary power supply of the test chamber is cut off by an AC contactor. However, the security system is not affected and works normally.
4. Tricolor Warning Light
The explosion-proof function of the high low temperature humidity test chamber meets the industrial requirements of the wide electronics and military industries.
