Foil roll

- for low-tension applications. This roll is intended for all foil applications including finishing foil for aluminium.

The foil roll has a pressductor sensor with a somewhat different design compered to the standard sensor. While sharing long-term stability e.g. no sensitivity drift and other important Pressductor characteristics with the standard sensor, the foil sensor has a better signal to noise ratio. This makes the sensor extremely well suited for low-tension applications like aluminium or copper finishing foil.
