Abstract
Two horizontal holes are processed at the end face of a movable pillar of a load measuring cell in a block shape. A power-point spring is formed between the horizontal holes, and the internal side faces of the horizontal holes constitute the internal end faces of supporting-point springs. Further, from above or below the load measuring cell, a vertical hole is processed so that the supporting-point springs are separated by the vertical hole extending in a vertical direction and are formed on both side faces in the longitudinal direction of load measuring cell.
Claims4
An electronic balance having a block-shaped load measuring cell, said load measuring cell comprising:
- a Roverbal mechanism for transmitting a measuring load in a vertical direction;
- a supporting-point spring for exerting the measuring load and a rotational moment of an electromagnetic force;
- and
- a movable pillar coupled with a power-point spring and a load receiver to which the measuring load is applied,
- wherein said load measuring cell is provided with at least two horizontal holes arranged in parallel at an end face of the movable pillar or an end face of a fixed pillar of the load measuring cell, so that a width of the power-point spring is controlled by a non-processed area between the horizontal holes and an internal side face of the horizontal holes constitutes an internal end face of the supporting-point spring.
