Patent ID: 8153913

Claim:
A gravimetric measuring instrument, comprising: a weighing cell, comprising: a parallel-guiding mechanism, which includes a movable parallelogram leg, a stationary parallelogram leg, and upper and lower parallel-guiding members, each of the parallel-guiding members joined to each of the parallelogram legs at a flexure pivot, so that the parallel-guiding members guide vertical movement of the movable parallelogram leg and connect the respective parallelogram legs; and a measurement transducer; a flexible tubular-shaped encapsulation, one end of which is attached to the stationary parallelogram leg and the other end of which is attached to the movable parallelogram leg, so that at least the parallel-guiding mechanism and the measurement transducer are enclosed by the encapsulation and thereby protected against dirt and humidity; an adjustment region, formed at at least one of the respective parallelogram legs, the adjustment region allowing adjustment of a distance between at least one of the flexure pivots of the upper parallel-guiding member and one of the flexure pivots of the lower parallel-guiding member, and an adjustment-setting area, arranged outside the encapsulation and mechanically connected to the adjustment region, to allow changes to be made thereto.
