Why choose the PMS-FF Sensor for your company?
Learn about the benefits of using the PMS-FF Sensor in your company.

The PMS-FF sensor is a high-tech double capacitive sensor capable of measuring multiple layer and barrier films. The sensor is installed after the nip roller where it measures at both edges of the lay-flat film.
The two sensors position themselves automatically at the edges of the film where they follow any changes in width. Both thickness and width are measured and transmitted to the computer and displayed on the screen.
The thickness measurement is processed by the computer which activates the adjustment units of the SmartLip automatic air ring to automatically correct the thickness profile. All integrated components are manufactured exclusively with Octagon technology.
