Abstract:
1. An electronic measuring device for measuring and displaying a linear displacement of a horizontal screw mechanism, the device comprising: a gravity acceleration sensor, said gravity acceleration sensor measuring an angle of rotation value of a horizontal rotational shaft of a screw mechanism; a data processing unit, said data processing unit converting said angle of rotation value into a linear displacement value according to characteristics of the linear screw mechanism; and a digital display unit, said digital display unit displaying said linear displacement value; wherein said gravity acceleration sensor, said data processing unit, and said digital display unit are electronically or electrically connected, wherein said data processing unit converts said angle of rotation value into said linear displacement value according to the formula: L=(S/360°)*θ, wherein L is the linear displacement value; S is the lead; and θ is the angle of rotation value.
