Displacement Sensors for Measuring Polyethylene Thickness
Thickness of Polyethylene Films May Be Measured by Confocal Displacement Sensors
The thickness of polyethylene films may be measured in-line by using confocal displacement sensors. These ultra-precise sensors measure the thickness of thin, transparent sheet by simultaneously measuring both the top and bottom surfaces. The measurement probe is aimed perpendicularly to the sheet surface and the sheet must be stabilized during measurement so it’s vibration amplitude does not exceed the span of the sensor system.

The Zenith controller is a next generation solution for non-contact, confocal measurements. Paired with a confocal pen, the Zenith controller can take measurements of unrivaled accuracy on surfaces where lasers struggle. Depending on the confocal pen chosen, the Zenith controller can take measurements with errors as low as +/- 35 nanometers. A new Dual Channel version can support two pens for simultaneous, synchronized measurement perfect for thickness applications.
