摘要:
A method and an apparatus for dynamically checking the weight of objects (18a-c) which are guided across a weight-sensitive zone (14) of a weighing device (12) at an adjustable conveying rate by a conveying mechanism (20a-c). At regular intervals, the weight-sensitive zone (14) supplies individual measured weight values (E1, . . . , En) from which resultant weight values are derived in a digital evaluation unit (16) by averaging. The evaluation unit (16) includes a plurality of cascaded averaging filters (24a-e) which have different filter lengths that are varied by a common scaling factor depending on the conveying rate.
摘要:
A precision force transducer having a spring element (1) whose load-dependent deflection is converted into an electrical signal by means of strain gauge elements (10). The spring element (1) is made of a precipitation-hardenable nickel-based alloy with a nickel content in the range of 36 to 60 percent and a chromium content in the range of 15 to 25 percent. The strain gauge elements (10) are composed of a polymer-free layered film system. This makes it possible to produce a precision force transducer that features great accuracy, low creep and low moisture sensitivity.
摘要:
Electronic scales having an integrated computer including a display for presenting information to a user, an input unit for entering selection data by a user, a memory for storing a plurality of activatable profiles as sets of parameter values for assignment to corresponding sets of parameters, and a data processing unit for controlling the display, the input unit, and the memory, and for determining and processing measured values in accordance with the current activated profile. The measured values are generated during a weighing operation by the user. To determine a profile, a user is requested, over a plurality of successive steps, to select one of several options presented by the display, the combination of the options presented in a step being dependent on the selection made in the preceding step. Then, during the weighing operation, the user is requested, again, over a plurality of successive steps, to perform an action presented by the display. A request, is a function of the type of actual current activated profile, and is made only if the action requested in the preceding step is confirmed as carried out.

摘要:
Measurement amplification methods and devices for detecting the detuning of a measurement bridge (10) to which a bipolar, rectangular supply voltage (Us) is supplied. The methods and devices use integrating A/D conversion and are characterized in that a reference voltage (Uref) used for the A/D conversion undergoes polarity changes synchronized with the polarity changes of the supply voltage (Us). Offset and drift are eliminated by totaling an even number of individual measurements.
摘要:
A weighing system that works on the principle of electromagnetic force compensation. The weighing system has two guide members (4′), which connect a load support (5′) to a base region fixed to the housing. The weighing system also has at least one transmission lever (6′), which is mounted on the base region. The base region is divided into two separate subregions (2′, 3′), the transmission lever (6′) extends between these two subregions. Two weighing systems are arranged laterally side by side and their base regions are interconnected in such a way that the two subregions (2, 3) of the base region of the one weighing system are connected to the two subregions (2′, 3′) of the base region of the other weighing system such that their positions are fixed relative to each other.
摘要:
An electronic scale having an integrated computer with an input unit for entering selection data, a memory for storing a plurality of parameter values, which can be assigned to function-specific parameters dependent on the entered selection data, a data processing unit for executing weighing applications dependent on a subset of the function-specific parameters and at least one interface for interacting with mechanical and/or electronic components dependent on a subset of function-specific parameters. A plurality of different profiles (24; 24′) can be stored as individual parameter value sets to adapt to user-specific and/or application-specific requirements. Selecting a specific profile (24; 24′) causes a joint assignment of the values contained therein to the corresponding parameters. The parameters are assigned to a plurality of non-overlapping parameter groups (26, 28, 30), each individual profile (24′) only contains those values that can be assigned to the parameters of precisely one parameter group (26, 28, 30), and each parameter group (26, 28, 30) can be assigned the parameter values of at least one profile (24).

A device for dosing a number of constituents according to a given formula with a scale (1) containing a formula memory. The scale (1) is equipped with a transponder read unit (2), the given formula is storable in a transponder (4) and transmittable to the formula memory with the transponder read unit (2) and the transponder read unit (2) additionally monitors the dosed constituents during the dosing process. The storage containers (6) for the individual constituents are each provided with transponders (7), so that the individual constituents can be identified by the transponder read unit (2). This enables a simple and reliable transmission of the formula data to the formula memory of the scale and monitoring of the dosing process. Furthermore, the scale can be operated in a generally contact-free manner.
