Fig. 1: Load Measuring Pin model LE 621, LE 418 (back); LE 217 & LE 211 (front) Magtrol Load Measuring Pins are used to measure load and force, and provide overload protection. The pins are mounted into machines in place of normal shafts and fitted with strain gauges, allowing them to produce a signal proportional to the measured load. Manufactured in Switzerland, Magtrol’s LE Series Load Measuring Pins are rugged with high resistance stainless steel and tight construction. Available in several standard ranges from 2.5 kN to 1 250 kN, their operation remains trouble-free and reliable even in electromagnetically difficult environmental conditions. When forces acting on mechanical constructions are measured, the additional equipment required can often be costly and difficult to install. Magtrol Load Measuring Pins offer an excellent solution since they act as a direct element in the assembly, replacing a non-instrumented pin or shaft. LE Series Load Measuring Pins are used for measuring loads and overload protection on cranes, hoisting gear, elevators and winches. The integrated electronics makes them ideal for applications in which separate signal conditioning is difficult to install and where the monitoring electronics are positioned at extended distances. © 2020 MAGTROL | Due to continual product development, Magtrol reserves the rig

LE SERIES DESIGN Magtrol's Load Measuring Pins have two circular grooves and an axial bore. Inside the central bore, adjacent to the external grooves, the strain gauges are mounted in a fullbridge configuration. The positioning and orientation of the strain gauges have been optimized by means of the finite element method (FEM). Lateral support Keep plate Cable Pendular bearing Cylinder head OPERATING PRINCIPLE When force is applied to the Load Measuring Pin along its sensitive axis, the effect on the strain gauge bridge results in an output signal proportional to the applied force.
