- Introduction
- Feedback
The capacitive displacement measurement system is a non-contact displacement measuring instrument, which consists of a capacitive sensing probe and a sensing and power supply module. It can measure small displacements within the range of 0-1mm with a measurement accuracy of up to nanometer level.
