Title:
DISPLACEMENT SENSOR
Document Type and Number:
WIPO Patent Application WO/2010/120042
Kind Code:
A3
Abstract:
Disclosed is a displacement sensor to measure displacement of a variety of devices depending on a slight deformation of the devices, based on moment of force acting on a diaphragm when the diaphragm undergoes displacement. The displacement sensor includes a sensing body and a signal processing unit. The sensing body includes a diaphragm provided at a lower surface thereof, to which a strain gauge is attached, and an input bar orthogonally fixed at the center of an upper surface thereof, to which displacement is transmitted. The signal processing unit generates an electrical signal based on an output value of the strain gauge corresponding to strain of the diaphragm caused by moment of the input bar.
