Force measurement using an inductively coupled sensor

Force measurement using an inductively coupled sensor

A low‐compliance, high‐bandwidth force sensor is described. The bending of a quartz plate is converted to an analog voltage by using a phase‐locked loop to measure the change in frequency of two oscillators inductively coupled to the plate. The resolution of the sensor is approximately 10−5 N, with...

Zusammenfassung:A low‐compliance, high‐bandwidth force sensor is described. The bending of a quartz plate is converted to an analog voltage by using a phase‐locked loop to measure the change in frequency of two oscillators inductively coupled to the plate. The resolution of the sensor is approximately 10−5 N, with a bandwidth of approximately 1 kHz.
