An accurate measuring balance for measuring forces or pressures, comprising a travelling mass for bringing a balance arm to equilibrium, which travelling mass is shaped as a body of revolution which can roll on the upper edge of the balance arm, and is mounted in a frame which is movable by an electric motor in the longitudinal direction of the balance arm. The frame comprises rotatable members contacting, in the equilibrium position of the balance, the body at both sides in the horizontal median plane.
