Overview
Programmable constant temperature and humidity testing machine NBC-408L-40 (paint plate) is mainly used to detect the performance of materials in various environments, test heat resistance, cold resistance, dry resistance, moisture resistance characteristics. Suitable for mass inspection of electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, aerospace and other products. Control mode adopts equilibrate Conditioning Control System (BTHC), which transmits the data in the box to the controller through the induction system. The controller controls the SSR to realize multi-stage intelligent output, equilibrate the temperature and humidity system power, ensure the stability of temperature and humidity, and have energy saving functions.
Features
1. The product has beautiful appearance, reasonable structure, precise process, simple and convenient operation, stable and reliable performance.
2. The controller adopts a large-scale color liquid crystal man-machine touch dialog LCD interface, which is easy to operate, stable and reliable. It displays the system status and setting Linear dispersion in Chinese and English, and supports remote control of RS232 computer interface.
3. The refrigeration circulation system adopts the original imported Japanese "Sanyo" brand fully enclosed Compressor (optional French Taikang), the components are from Japan, France, the United States, Italy, etc., and the refrigerant is the American environmentally friendly refrigerant (R23A, R404A).
4. Reserve a 50mm diameter test hole on the left side of the box.
5. Equipped with Fully Automatic, High Precision System Loop, P.L.C Locking Processing, P.I.D Automatic Calculation Control, High Accuracy and High Stability of Temperature in the Whole Zone.
6, special design of air circulation and air circulation and sensing system, the trend and return air sensor control, to ensure uniform temperature, avoid dead angle.
7. Adopt enlarged observation window, 4 layers of whole empty tempered Glass, wide field of vision.
8, the instrument has a comprehensive protection system, including power overload, leakage, control loop overload, short circuit, Compressor, grounding, over temperature protection and alarm prompts, abnormal automatically display fault and stop.
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 realizes multi-stage intelligent output by controlling the SSR, and the output power of the equilibrate temperature and humidity system ensures that the temperature and humidity in the box are fully stable. At the same time, it has the function of energy saving, reducing the power used, 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 is 380V/50HZ, and the allowable value of variation is +/- 10%.
2, through the controller to set the required temperature and humidity program Linear dispersion.
3. Start the instrument, and the system will automatically operate and monitor the temperature and humidity.
4. Observe the window and controller display to ensure normal operation.
5. When abnormal, the instrument automatically stops and displays the fault point.
Notice
• The working environment temperature should be kept at 0~ 30 ℃, and the performance guarantee environment is 5~ 25 ℃.
• The use environment requires that Miscellaneous items cannot be placed within 60CM of the instrument.
• Regularly check the protection system to ensure that the protection functions such as power overload and leakage are normal.
• Pay attention to the controller display during operation to avoid setting errors.
• Turn off the power during maintenance to prevent the risk of electric shock.
