The BTS 8101.EO O-frame is based on the combisensor principle. The system is equipped with a non-contact capacitive sensors and a Thrubeam sensor which are integrated in a traversing frame.
The eddy current sensor measures the reference distance to the measurement roll‘s metal surface. The distance from the film surface is measured by the Thrubeam sensor. Together with the reference signal the film thickness is calculated. This combisensor principle allows extreme precise measurements.
- Gap 22 mm
- Accuracy 3µm
- Material independent measurements
