Abstract: A high precision weighing system and weighing method has a weighing plate and weighing unit separation mechanism and a weight loading mechanism. The weighing plate and weighing unit separation mechanism controls separation of a weighing plate and a weighing unit, so that the weighing plate or the weighing plate and its carried material do not apply force to the weighing unit. The weight loading mechanism loads a weight onto the weighing unit or removes a weight from the weighing unit; the weighing system records a weighing value of the weighing unit during the action of the weighing plate and weighing unit separation mechanism and a sensitivity value during the action of the weight loading mechanism. The weighing system modifies the weighing value at the time of the most recent combination of the weighing plate and the weighing unit based on the recorded weighing and sensitivity values, achieving a high precision.

Abstract: A method for configuring a calibration mechanism in a force sensor (100) has the steps of: coupling an end of the calibration lever (1071) to a loading end (102) of the force sensor; adjusting, in a no-load condition, the center of gravity (G0) of the unloaded calibration lever (1071), so that the center of gravity (G0) lies on a horizontal line (H) through the center of a calibration lever fulcrum (1031) at a fixed end (103) thereof; and adjusting, in a full-load condition, the center of gravity (G1) of the calibration lever (1071) loaded with the calibration weight (106), so that the center of gravity (G1) lies on the horizontal line (H) through the center of the calibration lever fulcrum. The calibration error caused by inclination in the force sensor is reduced by practice of this method.

Abstract: A method for adjusting parameters of a device with a weighing sensor collecting environmental parameter data of an environment where the device is currently located or environmental parameter data during execution of an application by the device. A zero compensation parameter is calculated and updated, based on the data collected. The method is applicable to a moisture analyzer and also to a vehicle scale. In the moisture analyzer, the method is triggered and executed in the analyzer, correcting the zero compensation data by using the environmental parameter data of an environment or environmental parameter data during execution of an application by the analyzer. Dynamic and real-time adjustment of a compensation parameter overcomes the problem that the scheme of pre-setting fixed parameters for zero compensation cannot deal with the complex zero drift encountered in actual environments.

Abstract: In the method of optimizing the dosage-dispensing process of a dosage-dispensing device, an examination takes place prior to a first dosage delivery, whether at least one flow parameter relating to the dosage-dispensing process is stored in the memory module of the dosage-dispensing unit. If a stored flow parameter is found to be present, said flow parameter is called up from the memory module. If no store flow parameter is present, a flow parameter is requested by the user by entering a request, a flow parameter is called up from a central database, or at least one flow parameter is determined by means of the first run of the dosage-dispensing process based on a default setting of the dosage-dispensing program. With the at least one flow parameter, the dosage-dispensing program is directly adapted, at least one run of the dosage-dispensing process is performed with the adapted dosage-dispensing program, and/or the at least one flow parameter is stored in the memory module.

The weighing cell has a parallel-guiding mechanism and at least one measurement transducer. The ends of the encapsulation are attached, respectively, to the stationary parallelogram leg and the movable parallelogram leg, so that at least the parallel-guiding mechanism and the measurement transducer are enclosed by the encapsulation, protecting them from dirt and humidity.

This adjustment region is mechanically connected to at least one adjustment-setting area, which is arranged outside the encapsulation and allows changes to be made to the adjustment region.

Abstract: The calibration weight arrangement for an electronic balance (1) with a force-measuring cell (6) has a calibration weight (14) which can be coupled to the force-measuring cell (6). A transfer mechanism and a drive source are used to move the calibration weight vertically, in order to establish, as well as to release, the force-transmitting contact between the calibration weight and the force-measuring cell. The transfer mechanism has at least one resetting element (122), a lifting system (110) configured as a knee-joint linkage (117), and a multi-stable positioning element (115). Due to the feedback from the multi-stable positioning element, whose first stable state defines the calibrating position (132) and whose second stable state defines the rest position (133) of the transfer mechanism, the actuator (118) is energized only during the phases when the transfer mechanism is moving.
