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.

Description

technical field

[0001] The present invention relates to displacement sensors that measure the displacement of various devices based on small deformations of the device, and more particularly, to displacement sensors that measure the displacement of a device based on a moment of force acting on a diaphragm as it undergoes a displacement . Background technique

[0002] An example of a conventional displacement sensor is in Figure 7 in the icon.

[0003] The conventional displacement transducer 300 of this illustration comprises: a body 310 mounted to the mechanical device D1; an input rod 320 integrally extending from the body 310 in the form of a cantilever, the distal end of the input rod 320 is connected to the body of the mechanical device D1 The partial area D2 is in contact so as to experience displacement according to the displacement of the partial area D2; the strain gauge 331 attached to the input rod 320; and the circuit board 332 generating an electric signal whe...
