In a weighing scale including a load receiving member (2) being elastically deflectably guided by virtue of a parallel guide mechanism (3, 4) is provided an electromagnetic compensating system (12, 13, 16) for detecting the deflection which is proportional to the load. In order to achieve high precision and a simple construction, a lever (6) being located between said compensating system and said load receiving member (2) is supported on an elastic member (11), thereby preventing any positional changes in the compensating system or any non-homogeneity errors associated therewith (FIG. 1).

Load measuring apparatus, in particular weighing scale

A scale-type measuring apparatus, particularly a weighing apparatus, for use in commerce where calibration is required, comprises a sensor (1) which generates a signal representing a measured quantity, a separate readout device (3) disposed remotely from the sensor (1), a signal line (2) connecting the sensor to the readout device and an identification plate (7) for displaying authenticated values of technical measurement parameters of the sensor (1) on the readout device (3). In order to maintain the official calibration identification plate (7) must be unremovably linked to the sensor (1) and in order to enable separate handling of the sensor (1) and the readout device (3) despite this required permanent linkage of the identification plate (7) to the sensor (1), the signal line (2) is inseparably connected to the sensor (1), and the identification plate (7) is unremovably attached to and guided on the signal line (2), so that the identification plate (7) remains linked to the sensor (1) even if the coupling (5, 6) with the readout device is released. A characterizing number (integer) may be set (19) on identification plate (7), this setting being secured by a lead seal (21) applied at the time of official calibration.

Measuring apparatus

To support the load bed of a scale on the load lever, the invention provides load uprights each having a relatively rigid central section and elastic load-bearing end sections. The end sections are inserted in cup-shaped support seats on the load bed and the load lever respectively.
