<p>A force measuring device comprising a load receiving platform (22) supported by a multiple bending parallelogram beam type load cell is provided with a plurality of electrical strain gauges (1-4). Strain gauge elements (1, 2) mounted on one of the beams (16) are disposed toward one side of the beam and strain gauge elements (3,4) mounted on the other beam (17) are displaced toward the other side of the other beam. An appropriate resistor network is connected to at least one strain gauge on one or both of the beams to correct for either longitudinal or transverse displacement of the load on the platform (22). To correct for both transverse and longitudinal displacement of the load a resistor network is connected to each of three of the strain gauges. Suitable procedures for determining the values of the resistor networks in combination with the above structure are included.</p> |
