Thicknesscontrol Measuring Systems For Electrode Film

The quality of electrode film is crucial for increasing the performance of future battery generations. In order to generate higher energy densities, coating and calendering processes must be performed with the highest precision. Micro-Epsilon offers high-precision measuring systems for the thickness measurement of coated and uncoated battery film. These systems are equipped with high-resolution sensors and increase process stability, production speed and quality in modern coating lines.

White light interferometers use infrared light in the non-visible range (approx. 840 nm wavelength), which means that the measurement position cannot be seen. To visualize the measuring position, Micro-Epsilon systems are equipped with a pilot laser which projects a light spot onto the measuring position. In addition, the pilot laser uses a patented method to provide feedback on the distance in addition to the measurement position. If the measuring object is at the correct distance and within the measuring range, a constant glow is emitted by the pilot laser. If the measuring object is outside the measuring range, the pilot laser flashes.

The capaNCDT DT61x4 is an active, capacitive system for displacement, distance and position measurements. Consisting of a sensor with integrated preamplifier, a robust cable and a compact controller, the measuring system is immediately ready for use without any on-site calibration. The measuring system is available with a cable length up to 15 m and is ideal for automation purposes. The capaNCDT 61x4 is particularly suitable for automated robot manufacturing and measurement tasks with a drag chain. Moreover, it is used in machine building and semiconductor production. For optimum signal quality, the desired cable length is already factory-calibrated.

The capaNCDT DT61x0/IP is an industrial-grade, capacitive sensor system for displacement, distance and position measurements. Consisting of a sensor, a sensor cable and a controller, the measuring system is ready for use without any on-site calibration. Due to its very good temperature stability, immunity to magnetic fields and robust design that is protected to IP68, the capaNCDT DT61x0/IP is used for industrial measurement tasks such as air gap measurement in generators and regulation of plant and machinery.
