Overview
Programmable constant temperature and humidity testing machine NBC-150L-20 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), all parts are imported parts, and 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, including 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
1. Linear dispersion of system operating conditions, execution and setting procedures through the controller.
