Thanks to recent technical advances, relatively inexpensive capacitance thickness gauges reportedly are now stable enough for reliable closed-loop control, not just monitoring thickness variations. Another big step forward for capacitance gauges is the arrival of non-contact heads that can be mounted on the bubble instead of farther downstream on the layflat, thereby allowing quicker response to thickness variations.
