Overview
Programmable constant temperature and humidity testing machine NBC-800L-60 (paint plate) is mainly used to test the performance of materials in various environments, test the heat resistance, cold resistance, dry resistance and moisture resistance performance of various materials. Suitable for mass detection of electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, aerospace and other products.
Features
1. The product has beautiful appearance, reasonable structure, precise process, simple and convenient operation and stable and reliable performance.
2. The controller adopts a large-scale color liquid crystal man-machine touch dialog LCD man-machine interface controller, which is easy to operate, easy to learn, stable and reliable. The complete system operation status, execution and setting program Linear dispersion are displayed in both Chinese and English, which can realize RS232 computer interface docking and directly control the instrument remotely through the computer.
3. The refrigeration circulation system adopts the original imported Japanese "Sanyo" brand fully enclosed Compressor (purchased from France Taikang Compressor), and each component adopts imported components, which are from Japan, France, the United States, Italy and other origins. The refrigerant adopts the American environmentally friendly refrigerant (R23A, R404A).
4. The left side of the test chamber has a test hole with a reserved diameter of 50mm.
5, with fully automatic, high-precision system loop, any part action, with P.L.C locking processing, all using P.I.D automatic calculation control, the whole area temperature with High Accuracy, High Stability.
6, Specially designed air circulation circulation system and sensing system, out of the trend in the return air sensor detection and control, to ensure that the test chamber Temperature Uniformity, to avoid any dead angle.
7. Adopt enlarged observation window, 4 layers of whole empty tempered Glass, wider field of vision.
8, the instrument has a comprehensive protection system, power overload protection, leakage protection, control loop overload, short circuit protection, Compressor protection, grounding protection, over-temperature protection, alarm sound prompts, etc., when any abnormal situation occurs, the screen automatically displays the fault point and cause and automatically stops.
Principle
The equilibrate Conditioning Control System (BTHC) is adopted, and the induction system transmits the actual data in the test chamber to the controller. The controller controls the SSR, multi-stage intelligent output, and the output power of the equilibrate temperature and humidity system to ensure that the temperature and humidity in the test chamber are fully stable, and It has the function of energy saving, reducing the power of the instrument to a greater extent, and ensuring the long-term accurate and stable operation of the instrument.
Applications
Electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, aerospace
Steps
Connect the power supply to ensure that the voltage meets the requirements of 380V/50HZ, and the allowable voltage fluctuation is +/- 10%.
2. Set the required temperature and humidity program through the controller Linear dispersion.
3. Start the instrument, and the system automatically executes the setting program to monitor temperature and humidity changes.
4. Use the observation window to check the test process, and if necessary, conduct external inspections through the test holes.
5. After the test is completed, the system will automatically shut down and the data can be exported through the computer remote control interface.
Notice
• The working environment temperature should be kept at 0~ 30 ℃, and the performance guarantee environment is 5~ 25 ℃.
• Use environment requirements: Miscellaneous items cannot be placed within 60CM of the instrument.
• Power supply voltage stability to avoid overload or leakage risk.
• Check whether all protection systems are normal before operation, including over-temperature protection and alarm functions.
• Regularly maintain the refrigeration cycle system and Sensors to ensure long-term stable operation.
