A platform type weighing scale including a base and a scale platform and first and second pairs of platform suspensions for mounting the platform on the base at the four corners of a generally rectangular pattern, an elongated load sensing beam supported at spaced points therealong on the base, and first and second transfer means respectively interconnecting the first and second pairs of platform suspensions to the beam at a common point intermediate the spaced beam suspension points to apply a bending load to the beam correlative with the sum of the loads applied to the first and second pairs of platform suspensions, and electrical strain gauge means mounted on the load sensing beam for producing an electrical signal correlative with the bending stress produced in the beam as an indication of the total weight applied to the scale platform.
