Filed: 2001-08-20
Abstract: PROBLEM TO BE SOLVED: To provide a load sensor capable of automatically calibrating output changes caused by temperature changes and degradation with time and highly accurately detecting load at all times. SOLUTION: A spring 3 of which load value is determined by the amount of stroke, is utilized to automatically calibrate a zero point and sensitivity at actuation or during use.
