Description

Shear beam load cells deliver exceptional stability in the case of lateral or side forces. Shear strains on the spring element do not change when the load application point moves within a specific range, which is desirable in applications where the load application force varies. Therefore, the electrical signal output of the strain gauge bridge is proportional to the applied force, regardless the point where the load is applied.

Shear beam load cell is also known as bending load cell, parallelogram load cell or Parallel Beam Load Cell, is widely used in industrial weighing scale and general measurement applications where robustness is required.
