Abstract
A sensor and a method for determining the coating weight of a coating material containing silicone on a substrate is described. The determined coating weight is insensitive to changes in the amount of substrate material underlying the coating. Signals from the sensor may be used in the control of a coating mechanism to provide a coating having a uniform weight.
