Linshang LS152 vacuum coating thickness measuring system uses 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, solar 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 10 test points. The actual length of the device is based on the number of customized test points.
Vacuum coating thickness measuring system appearance
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).
instrument installation diagram
The equipment is mainly divided into three parts: console, human-machine interface, computer real-time monitoring software (optional)
1. Console: mainly includes light source probe, receiving probe, controller, aluminum profile frame.
internal structure display of the console
2. Human-machine interface: It mainly includes human-machine interface, power supply and stainless steel box
3. Computer real-time monitoring system (optional): Real-time monitoring of the data, including real-time display, histogram, setting of upper and lower limits, real-time curve and alarm when the limit is exceeded. The transmittance and optical density display can be switched freely.
1. The ultra-small controller is embedded in the console. It is easy to use and install. We only needs to connect 6 wires.
2. The instrument use optical non-contact measurement, without direct contact with the test material. It will not cause damage to the tested material.
3. The vacuum coating thickness measuring system has high measurement accuracy which can be compared with the United States Germany NAGY online thickness measurement equipment.
4.The instrument use modular design, single point is removable, which is convenient for future maintenance.
5. Dust-proof design, dust does not affect the inside of the gyroscope. Customers just need to clean the front glass of the probe.
6. Use RS485 interface + MODBUS communication protocol. The instrument can achieve closed-loop control with the coating machine.
7. The instruemtn has over-limit alarm function and can intelligently control production quality. The instrument can reduce dependence on personnel and improve production efficiency and quality.
