Overview
Programmable constant temperature and humidity testing machine NBC-1000L-20 is a factory direct sales of high and low temperature heating and humidity alternating test chamber, mainly used to detect the performance of materials in various environments, test the heat resistance, cold resistance, dry resistance of various materials, moisture resistance performance. Suitable for electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, aerospace and other products to detect mass, using equilibrate Conditioning control system (BTHC), through the induction system will test chamber the actual data transmission to the controller, the controller controls the SSR to achieve multi-stage intelligent output, equilibrate temperature and humidity system output power, to ensure that the test chamber temperature and humidity fully stable, and has energy-saving function.
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 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 test chamber are fully stable, and has energy-saving functions. Reduce the power of the instrument to a greater extent and ensure 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 through the controller setting program.
2. Start the instrument for testing.
3. Monitor system operation status and execution procedures.
4. Automatic shutdown and malfunction display when abnormal.
Notice
• The operating environment temperature should be kept at 0~ 30 ℃.
• performance to ensure that the environment temperature is 5~ 25 ℃.
• Miscellaneous items cannot be placed within 60CM of the instrument.
• Note that the Power supply voltage is 380V/50HZ, and the allowable voltage variation is +/- 10%.
• Regularly check the water quality of the humidification system to filtrate and avoid blockage.
• Use the bottom casters when moving the instrument, pay attention to load bearing and shock absorption.
