Abstract: A load cell, one end of the cell being mounted on a base and the other end of the cell being arranged for connection to a force applicator so that in operation applied loads are transmitted vertically to said other end to distort the cell, and wherein the cell houses a vibrating beam force sensor lying in a plane parallel to the base, the cell being so arranged that the vertical force produced by an applied load to the force applicator is translated into a horizontal force applied to the vibrating beam force sensor.

Abstract: In a load cell for a weighing machine, the load cell includes a vibrating beam force sensor clamped at its two ends to respective support parts of the load cell, and wherein each end of the sensor is clamped by a bolt having a head which traps the associated end of the sensor against a support part, the bolt having remote from its head a threaded portion engaged with a nut which tensions the bolt, and a portion of non-circular cross section having at least one cross sectional dimension which is greater than that of the threaded portion, the non-circular cross section portion of the bolt having been drawn through a hole in the support part which had a diameter less than said one cross sectional dimension. This reduces the production of forces parallel to the plane in which clamping is required.
