LINSHANG LS152 Vacuum Coating Online Thickness Gauge

LS152 vacuum coating online Thickness Gauge testing principle

   There is a certain proportional relationship between the transmittance (optical density) of the material and the coating thickness of the material. In this way, the uniformity of the material and the thickness of the coating can be monitored by monitoring the optical transmittance (optical density) of the material. As long as it is a material that can transmit light, the quality of the product can be monitored by monitoring the light transmittance. Such as winding vacuum coating, glass coating, glass production line, etc.

LS152 non-contact online Thickness Gauge structural composition

   The equipment is divided into three parts: detection system, human-computer interaction equipment, and computer real-time monitoring system;

   Detection system: mainly includes light source, receiver, controller and aluminum bracket;

   Human-computer interface: 7-inch LCD human-computer interaction interface, showing the transmittance and optical density data of each test point;

   Computer real-time monitoring system (optional): data recording, analysis, reporting and other functions.

   This instrument provides dual-channel RS485 communication interface and standard MODBUS communication protocol, which facilitates communication with PLC, microcontroller, human-machine interface, KingView, computer, etc. The coating machine can directly read the optical density data of this equipment to achieve control automation (closed-loop control).
