20100044118 | ADJUSTABLE PARALLEL-GUIDING MECHANISM, SPECIFICALLY FOR A GRAVIMETRIC MEASURING INSTRUMENT - A parallel-guiding mechanism has a vertically movable parallel leg that carries a weighing pan. The movable parallel leg is connected by two essentially horizontal parallel guides to a stationary parallel leg installed in a balance, wherein elastic flexure pivots are formed at the ends of the parallel guides. Incisions that reduce the material strength of the parallel leg in at least one appropriate location define at least one adjustment domain, thus forming a deformation zone which is plastically deformed through application of an adjustment force. In this manner, a corner load error of the parallel-guiding mechanism is corrected. | 02-25-2010 |
20100044119 | ADJUSTABLE PARALLEL-GUIDING MECHANISM FOR COMPACT GRAVIMETRIC MEASURING INSTRUMENTS - In a parallel-guiding mechanism, a stationary parallel leg surrounds a movable parallel leg. The movable parallel leg is connected to the stationary parallel leg and guided in vertical movement by first and second parallel-guiding elements, fastened respectively to the upper and lower end portions. The movable parallel leg can be connected to a load receiver and to a force-measuring cell through a force-transmitting connection in order to transmit the weighing load. Intermediate to, and connecting, the respective end portions is a tilt-adjustment feature, by which the end portions are tilt-adjusted relative to each other about at least one tilt axis to correct a corner load error. The tilt-adjustment feature is provided by at least one of: a pair of bending zones, a spherical joint and a ring-shaped constriction. | 02-25-2010 |

20110017521 | GRAVIMETRIC MEASURING INSTRUMENT WITH RELEASABLE LOAD RECEIVER - A gravimetric measuring instrument that contains a weighing cell having a load-transmitting member. A load receiver can be coupled to the load-transmitting member through a releasable connection. A mechanical stop resides on the load-transmitting member, and a mechanical counter stop resides on the load receiver. By means of an eccentric bolt engaging the load receiver and the load-transmitting member, the mechanical stop can be pressed against the mechanical counter stop, whereby the stop can be clamped tight against the counter stop. With this arrangement, the load receiver can be rigidly but releasably secured to the load-transmitting member. | 01-27-2011 |

20130220711 | WEIGHING CELL BASED ON THE PRINCIPLE OF ELECTROMAGNETIC FORCE COMPENSATION WITH OPTOELECTRONIC POSITION SENSOR - A weighing cell based on the principle of electromagnetic force compensation and having an optoelectronic position sensor that includes a light source, a light receiver, and a shutter vane. The light receiver functions to generate a position sensor signal corresponding to a deflection of the shutter vane from a zero position which occurs as a result of placing a load onto a load receiver of the weighing cell. A controller functions to regulate compensation current in response to the position sensor signal in such a way that the shutter vane and the movable parts of the weighing cell connected to the shutter vane are returned to the zero position by the electromagnetic force between a coil and permanent magnet system of the weighing cell. | 08-29-2013 |

20120173168 | METHOD FOR THE TEMPERATURE-CORRECTION OF A FORCE-MEASURING DEVICE, AND FORCE-MEASURING DEVICE - An exemplary method for the temperature correction of a force-measuring device such as a balance is disclosed. The method includes generating, by means of a force-measuring cell, a force measurement signal corresponding to the input force; generating an electrical temperature measurement signal by means of a temperature sensor that is arranged at a distance from the heat-generating components of the force-measuring device, processing the force measurement signal into a temperature-corrected output signal based on the temperature measurement signal and the force measurement signal; and transmitting the output signal to an indicator unit and/or to a further processing unit. | 07-05-2012 |
