FLEXURE SCALE

摘要

F L E X U R E S C A L E The flexure scale is made of compact, inexpensive construction and includes a load frame which is supported via flexures from a stationary support frame. The load frame includes two oppositely directed beam arms which are displaced when a load is placed on the load frame. The two beam arms are connected together to permit a summation of their displacements and the longer beam arm is secured at the free end to the support frame by means of a spring which proportionally restrains the displacement of the beam arm. A linear variable differential transformer is mounted on the surface frame to emit signals corresponding to the displacements of the beam arms to a digital readout means. The electrical output of this transformer is adjusted to produce a fixed output for a standard load. A system composed of a multiplicity of these scales requires only a single read-out means.
