Abstract
The paper presents design and development of a resonance displacement sensor. The sensor is built with cantilever as a resonator with piezoelectric excitation and sensing in closed loop electronics. The sensor measures the unknown displacement with good linearity within the measurement range. The input displacement varies the length of the resonator by a fixed roller arrangement. The shift in resonance frequency for a change in displacement is detected by closed loop electronics.
