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.
