What technical features are used in the chamber results of the high and low temp

The high and low temperature test chamber is a relatively precise large-scale test equipment, so many professional design features are used in the design stage of the equipment. Today we will briefly understand the structure of the high and low temperature test chamber and its technical characteristics.

 

 

 

1. The box body is processed and formed by CNC machine tools, with beautiful appearance and non-reaction handle, which is easy to operate.

2. The inner tank of the box is made of imported high-grade stainless steel (SUS304) mirror panel, and the outer tank of the box is sprayed with A3 steel plate, which increases the appearance texture and cleanliness.

3. The water replenishment tank is placed in the lower right part of the control box, and has automatic water shortage protection, which is more convenient for the operator to replenish the water source.

4. The large observation window is equipped with a lighting lamp to keep the inside of the box bright, and the tempered glass embedded in the heating body is used to clearly observe the situation in the box at any time.

5. The humidification system pipeline is separated from the control circuit board, which can avoid failure due to water leakage in the humidification pipeline and improve safety.

6. The water system pipeline circuit system is convenient for maintenance and repair.

7. The box insulation adopts ultra-fine glass fiber insulation cotton, which can avoid unnecessary energy loss.

8. There is a test hole with a diameter of 50mm on the left side of the box, which can be used for external test power lines or signal lines.

 

The series of high and low temperature test chambers are suitable for testing various performance indicators of aerospace products, information electronic instruments, materials, electrical, electronic products, and various electronic components in high and low temperature or humid and hot environments.

 

The high and low temperature test box has good thermal insulation performance. The top surface of the box chamber is equipped with a blower, which is equipped with an air duct in the box, so that the hot air in the box circulates regularly, thereby improving the temperature uniformity in the box. The electric heater has a sealed tubular shape to prevent accidents caused by direct contact between the hot wire and the low ignition point gas.

 

AOTSI high and low temperature alternating test chamber is widely used in electronics, electrical appliances, communications, instruments, vehicles, plastic products, metal, food, chemical, building materials, medical, aerospace and other products for quality testing purposes. Applicable standards: GB/T2423.1 / IEC60068-2-1, GB/T2423.3 / IEC60068-2-78, GB/T2423.4 / IEC60068-2-30, GB/T2423.34 / IEC60068-2-38 , JESD22-A100-C, JESD22-A101-C, etc.

 

 

1. Adopt 7-inch intelligent programmable controller, with fast processing speed and clear interface display. With a variety of language options, test data U disk storage and LAN port and other functions.

2. This machine adopts high-stability platinum PT-100 temperature measuring resistance body, with multiple PID control functions, equipped with USB standard communication interface, which can be connected to a computer interface for remote control, and is equipped with simple and easy-to-understand high accuracy , The intelligent programming control system and fixed value control system provide the experimenter with all-round perfect test performance.

3. Fault tracing and automatic detection function:

The operating state before the failure of the high and low temperature alternating test chamber will be automatically recorded and saved. It can be forwarded to the nearest service window to implement remote fault diagnosis and integrated maintenance.

4. Remote monitoring communication and SMS alarm:

It is as simple as possible to remotely monitor the device through the local area network without any driver. After the mobile phone number is preset, the equipment fault alarm information can be received in real time.

 

The humidification system of the high and low temperature damp heat test chamber is roughly the same as the heating system. It is the process of heating water by a heater and turning it into steam to complete the purpose of humidification. The dehumidification system is also completed by the refrigeration system. The evaporator is placed in the test box, which is relatively cold, and the high-humidity gas inside meets the cold object and condenses into a liquid. In this way, there will be very little high-humidity gas in the box to achieve the purpose of dehumidification. The success of humidification and dehumidification also affects the success of the experiment to a certain extent.
