Brief introduction: Test principle: the material of transmittance (optical density) and a certain proportion relationship with material of coating thickness. So by monitoring materials of optical transmittance (optical density) to achieve the uniformity of monitoring materials, the purpose of the coating thickness. As long as it is light through the material, can be monitored by monitoring the light transmittance product quality. Such as winding vacuum coating, coating, glass production line and so on. Equipment is divided into three parts: detection systems, human-computer interaction devices, computer real-time monitoring system; Detection system: mainly includes the source, receiver, controller and aluminum bracket; Human-machine interface: 7 inch LCD man-machine interface, display the transmittance and optical density data of every test points, Computer real-time monitoring system (optional) : data record, analysis, reporting, and other functions. Technical parameters: 1. Test wavelength: according to the customer need to choose, there are the following options: Infrared: 850 nm (the default option, strong anti-interference ability) Green: 530 nm 2. The transmittance measurement precision, better than + / - 1% 3. The transmittance resolution: 0.005% 4. Optical density measurement range: 0.00 OD - 5.00 OD 5. The resolution of the optical density: 0.01 for 0.00 3.00 OD 0.05 for 3.00 5.00 OD 6. The maximum measured points: 36 points 7. The distance between adjacent detection head: minimum 70 mm 8. To send and receive distance between probe: 20 mm 9. The temperature range: - 20 ° C - + 70 ° C 10. Data refresh cycle: 300 ms 11. The measurement and control host size: 80 mm * 180 mm (wide) (high) * length (according to customer requirements) 12. Need some conclusions: vacuum flange electrode root (no computer monitoring), 6 to 9 root (with computer monitoring) 13. Power supply: AC 220 v / 50 hz 14. Communication: dual RS485
