Online monitoring of material uniformity and coating thickness Free to choose the number of test points, 45 test points can be customized at most Two-way RS485 communication interface, MODBUS communication protocol Strong anti-interference, data is stable Linshang LS152 vacuum coating thickness measuring system works in the principle that the transmittance (optical density) of the material is proportional to the coating thickness. The uniformity of the material is achieved by monitoring the optical transmittance (optical density) of the material. As long as the light can pass through the material, the product quality can be controlled by monitoring the transmittance (optical density). Because it can monitor two parameters of both transmittance and optical density, it is also called optical density online detector. This vacuum coating thickness measuring system is widely used in concentration vacuum coating machine, glass coating production line, window film coating line and other occasions. The user can freely choose the number of test points. The figure below shows the appearance of the vacuum coating measuring system with 9 test points. The actual length of the device is based on the number of customized test points. The instrument provides dual RS485 communication interface and standard MODBUS communication protocol, which is convenient for communication with PLC, Single Chip Microcomputer, human-machine interface, kingview, computer and so on. The optical density data can be read on the coating machine to realize control automation (closed-loop control).
