Abstract
The present invention refers to a method for determining the height of a foam blanket on an electroplating composition utilizing a radar signal, as well as a respective use.
Claims16
A method for determining the height of a foam blanket on an electroplating composition, the method comprising the steps:
- (a) providing in an electroplating compartment the electroplating composition,
- (b) providing an analysis compartment separated from the electroplating compartment, the analysis compartment comprising
- (i) means for blowing in a gas, and
- (ii) a radar emitter and radar sensor,
- (c) separating a portion of the electroplating composition and transferring said portion into the analysis compartment such that the analysis compartment is filled with said portion at a constant filling level,
- (d) in the analysis compartment, contacting the separated portion with the gas such that foam is created with a height, and
- (e) emitting a radar signal from the radar emitter onto the created foam and receiving a reflected radar signal on the radar sensor such that the height of the foam is determined.
