  • Load measuring apparatus, in particular weighing scale
    Patent number: 5315073
    Abstract: 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).

  • Electromagnetically compensated scale
    Patent number: 4168756
    Abstract: A balancing scale or electromagnetically compensated weighing apparatus has an independently actuatable and temperature-sensitive magnetic device for balancing a load member; the magnetic device forms a magnetic circuit, and includes a temperature-sensitive corrective device affecting the circuit in at least two locations, so as to substantially temperature-compensate the magnetic circuit over a predetermined temperature range.
