In a load cell, in particular for weighing systems, comprising a deformable member (1), this deformable member has an aperture (2) extending transversely of the direction of the force, which is closed by at least one disc-shaped wall which corresponds to the cross-section of the aperture and extends transversely of the axis of the aperture and serves to receive strain gauges which are deposited by means of a film technique. The deformable member is formed by two sub-members (3, 4) which are welded together in a plane which extends transversely of the axis of the aperture. A wall is provided in the aperture of each sub-member, at least one wall being provided at its interior side with strain gauges.
A load cell adapted to be positioned between a foundation and each of several support members for a storage vessel. The load cell includes a circular flex plate having a pair of concentric cylindrical members of different diameters secured to opposite surfaces. A mounting pad adapted to be fastened to the foundation is secured to one of the cylindrical members. A mounting plate is secured to the other cylindrical member. The mounting plate has either a single threaded bore or a threaded stud positioned at the common axis of the cylindrical members for securing the mounting plate to a vessel support member. A strain sensor mounted on the flex plate measures the load-induced deflection of the flex plate.
A load cell includes a deformable member having a chamber therein extending parallel to the direction of force. A plate on the deformable member extends transversely to the direction of force and to the axis of the chamber. The plate is welded to the deformable member such that it covers the chamber. The plate and welding carry the structural loads of the deformable member. Strain gauges are positioned on the interior sides of the chamber.
