Abstract

An electromagnetically compensating beam balance has a balance housing, a am and a fixed counterweight. Weight changing means, which change the weighing range (scale) by substitution, are provided on the load receiving side. A parallel guidance system is provided. Rods which accept only horizontal forces are coupled between a load carrier and the housing. Vertical flexure elements, which accept vertical forces, are coupled between the beam and the load carrier.
