Abstract:
1. 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, the power-point spring being coupled to the supporting-point spring, 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.
