Film thickness gauge thicknessCONTROL BTG 8702 C.C

dry filmcoatingstationary

Overview
Micro-Epsilon offers a range of thickness measuring systems for coating lines, designed for different requirements and fields of application. The thicknessCONTROL C-frames are engineered for harsh environments such as dry coating. Their robust frame and integrated temperature compensation ensure high measurement accuracy even at elevated ambient temperatures. Systems are available in different application-specific designs for various film widths and up to 8 measurement tracks.

Key features

• High-precision thickness measuring system for coated anode and cathode film
• Sensor technology used: confocal chromatic sensors
• Ideal for thickness measurement and control in dry coating
• Robust design with integrated temperature compensation
• Thickness measuring range from 10 µm
• System accuracy from ±0.3 µm
• Comprehensive software package for data acquisition, signal processing and automation
• Configurable for 1 | 2 | 3 | 4 | 6 | 8 tracks

Applications / Operation modes
Suitable for fixed track measurements (e.g., center-line or edge thickness) and for traversing thickness measurements of coated battery film. Systems can be equipped with several sensors to measure up to 8 tracks synchronously, enabling inline process control and SPC monitoring.

Software and system components
The thicknessCONTROL systems include an integrated linear unit with motor control, a compact bus terminal box, an automatic calibration unit and a multi-touch PC with pre-installed software. Measurement modes supported by the software include fixed track thickness measurement at any position, thickness profile measurement, measurement of several longitudinal trends, an SPC package and automated verification of the measuring system's capability.

Example system (BTG8702 2C.4K)
The thicknessCONTROL BTG8702 2C.4K consists of two robust measuring frames, each containing confocal sensors. The system monitors up to 8 tracks of coated film with a total width of up to 1.6 m. Robust design provides high-precision long-term measurements in dry coating processes. For fully automatic calibration, the measurement frames travel back to their parking station.
