Tensile and compressive stress data pick=up - has strain gauge carrier converting pure bending stresses calibrated via clamping nuts

摘要

The data pick-up detects tensile and-or compressive stresses of a bar-shaped force transmission member, for a lifting appliance. A mechanical transmission of the test stress is achieved. The force transmission element can be calibrated very simply via clamping nuts so that any compressive or tensile stresses present are compensated, and esp. accurately at zero balancing. The force transmission member has a through-hole along its longitudinal axis and this has a widening for wire strain gauges in its central region.
