Abstract
A force or weight sensor comprises a base that contains a permanent magnet, a compressible medium such a spring, torsion device or other such opposing force so as to provide an offset when a force or weight is applied and a linear Hall Effect sensor that has an electrical output responsive to the magnetic flux therein when conditioned provides the value of the force.
Description
DESCRIPTION
LINEAR HALL EFFECT FORCE WEIGHT SENSOR
The invention relates generally to the capability of providing a method for determining force or weight by the effect of the output of a linear hall effect sensor when the distance from a permanent magnet is provided by an opposing force such as but not limited to a spring or torsion device.
Background of the Invention.
Traditional Load Cells require complicated signal conditioning at a substantial cost to manufacture. The inventor provides for an alternate less expensive method of determining force or weight.
The placement of a linear hall effect sensor in proximity to a permanent magnet separated by a distance and corresponding force applied by a spring, torsion device or other opposite force so that the distance between the hall effect sensor and the permanent magnet effects a corresponding change in the output of the hall effect sensor relating to the force applied to bring the hall effect sensor closer to the permanent magnet.
