Measuring and inspection systems for plastics
Measuring and inspection systems from Micro-Epsilon are used in the plastics processing industry in order to ensure efficient production.
Application fields:
Film extrusion
Thickness profile of blown films
The systems of the BTS 8104 family are designed as reversing systems and are based on the capacitive technology. They are directly applied immediately behind the calibration cage on the bubble and therefore offer a very fast and efficient control. Adaptive reversing speed allows an ideal adjusting of the measurement to each step of the extrusion process. Therefore, these systems present the basis for a perfect film production regarding quality and material input.
Advantages:
- 100 % non-contact and contact capacitive measurement methods
- Different coating for different film types
- Adaptive reversing speed to ensure fast controlling
- No consequential costs due to isotopes or X-rays
- Short control loop ensured by measurement on the bubble
Material parameter:

The IDS 8100.C works with integrated capacitive displacement sensors. The actual bore diameters are detected over the whole process part length. As the axial sensor positions are detected as well using a cable-length measurement system, local deviations in diameter can be reliably and quickly found. In doing so, each sensor position is related to a diameter in the longitudinal axis of the bore hole.
