Single Ended Shear beam loadcell construction and installation

Single-ended shear beam load cells are manufactured from high-elasticity materials like 17-4 PH stainless steel bars, machined into a beam with recesses to create a thin central web for shear strain detection.

Single-ended shear beam load cells are installed by mounting the fixed end to a rigid base plate and applying vertical load centrally on the free end via a load introduction point like a cup, ball, or rocker pin.

Preparation Steps

Clean and level the mounting surface to ensure stability and accuracy, using a spirit level and removing debris. Mark and drill holes matching the load cell’s mounting pattern, typically with M8-M10 bolts for capacities up to several tons.

Mounting Process

Position the load cell over the holes, insert bolts through the fixed end’s mounting holes, and tighten evenly with a torque wrench to manufacturer specs to avoid misalignment or side-loading. Secure the base plate first if used, then attach the load cell; use mounting kits for shear beams to handle thermal expansion and ensure vertical force alignment within 0.5°.

Wiring and Calibration

Connect color-coded wires (e.g., red for excitation+, green for signal+) per the datasheet, grounding properly to prevent noise. Calibrate with known weights across the range, verifying output linearity, then test under load.
