Design of a Full-Range Capacitive Sensor Extensometer Using a High-Precision Ultrasonic Motor

Extensometers are critical instruments for accurately measuring small displacements in terrain deformation monitoring. Conventional extensometers often employ eddy current displacement sensors or differential transformer sensors, which are constrained by structural limitations that hinder their abil...
