Capacitive Sensors for Thickness Measurement and GaugingTwo channel capacitive displacement measurement systems are widely used for high speed, non-contact thickness measurement of conductive materials such as disk media and various machined parts. Thickness Measurement – Principle of OperationMost thickness measurements based on capacitive sensing are made using the two probe “A+B”, or differential, method. The following is the basic concept: 
The Formula for Thickness is: Where:- D= Distance Between The Probes
- A= Distance From Probe A to Material To Be Measured
- B= Distance From Probe A to Material To Be Measured
- T= Thickness Of The Material To Be Measured
