Description
Sistem pengukur ketebalan lapisan vakum Linshang LS152 bekerja berdasarkan prinsip bahwa transmitansi (kerapatan optik) material berbanding lurus dengan ketebalan lapisan. Keseragaman material dicapai dengan memantau transmitansi optik (kerapatan optik). Selama cahaya dapat menembus material, kualitas produk dapat dikontrol dengan memantau transmitansi (kerapatan optik). Karena dapat memantau dua parameter, yaitu transmitansi dan kerapatan optik, sistem ini juga disebut detektor daring kerapatan optik. Sistem pengukur ketebalan lapisan vakum ini banyak digunakan dalam mesin pelapis vakum konsentrasi, lini produksi pelapis kaca, lini pelapis kaca film, dan berbagai keperluan lainnya.
LS152 Vacuum Coating Thickness Measuring System Introduction
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).
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
Control console and installation method
The controller and the test probe are embedded in the control console and only need to fix the control console during installation. Each device is equipped with a bracket, which is customized according to the actual installation needs of customers. The installation diagram of the control console is as follows
Features
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.
4.The instrument use modular design, single point is removable, which is convenient for future maintenance.
5.With 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 manual operation and improve production efficiency and quality.
