Capacitive Transducers Construction and Working Principle, Application in Electronic Instrumentation
Summary
The video explains the inner workings of capacitive transducers in measuring displacement and pressure through two metal plates and a dielectric medium. It delves into factors influencing capacitance values like plate area, permittivity of free space, and dielectric material. It also covers how displacement is gauged using these transducers and the sensitivity they possess due to high output impedance.
