Thickness Measurement

Capacitive gauges for thickness measurement

 

Capacitance gages and sensors from ADE are used to make very precise thickness measurements of semiconductor wafers, as well as Hard Disk Drive platters and similar components, including continuous sheet material.

Thickness of non-conductive materials can also be measured using capacitance gauges. Since capacitive gauges are non-contact and have very high measurement bandwidth, they are ideal for applications requiring hundreds or thousands of measurements per hour.
