Product Description
Thickness is measured by using the reflection of a compressed air jet that is directly calibrated against the material as follows
- The distance between the air nozzle and the surface of the material to be measured is calculated with a special pneumatic transducer.
- The distance from the measuring head to the reference roll is measured by a high precision system with inductive sensor.
- In this way the thickness of the material is calculated as the difference between the reference roll detected by the inductive sensor and the distance from the reflection point measured by the air-blow sensor.
