LOAD MEASURING PINS LB Series Load Measuring Pins can be used alone or as part of a complete measurement system. Magtrol offers a wide range of Load-Force-Weight Transducers in various executions and accuracy classes and our Load Monitoring Units (LMU Series) constitute an ideal safe measurement system which continuously checks for overloads and short circuits. FEATURES ▪ For overload detection and load measurement: Nominal Load (NL): 2.5 ... 1 250 kN (0.28 ... 140.5 tf). ▪ Admissible Overload: 150 % (NL). ▪ Overload at Rupture: up to 500 % (NL). ▪ Insensitive to external mechanical and chemical effects. ▪ Ideal for use in hostile environments. ▪ Temperature-compensated transducers with strain gauges in full-bridge configuration. On request, available with double bridge redundant. ▪ Simple installation for cost-saving solutions to measurement problems. ▪ Many options may be added to the lower-cost standard load pin for greater flexibility. ▪ Can be designed with special dimensions for adaptation to various construction conditions with nominal load up to 3 300 kN (336.5 tf). ▪ High reliability for strict safety requirements. Fig. 1: LB 210 & LB 217 | Load Measuring Pins 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 LB 2XX Series Load Pins are rugged with high resistance stainless steel and tight construction, designed specifically for use in harsh industrial environments. Available in several standard ranges 2.5 ... 1 250 kN, these highly ergonomic pins can be used for either new or refitted installations and are adaptable to various 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. LB 2XX Series Load Pins are used for load measuring devices and overload protection on cranes, hoisting gear, elevators and winches, and force measurement for regulation processes in industrial installations and machinery production. Moreover it is an idealy transducer to detect and measure forces in harsh, tropical, offshore, marine and harbor environments. © 2021 MAGTROL | Due to continual product development, Magtrol reserves the right to modify specificati

LB SERIES DESIGN The Magtrol Load Pin has 2 circular grooves and an axial bore. Inside the central bore, adjacent to the external grooves, the strain gauges are mounted in a full-bridge configuration (double full-bridge for LB 23X models). The positioning and orientation of the strain gauges have been optimized by means of the finite element method (FEM). Any transverse or axial forces, even when acting on any part of the pin, have practically no influence on the measurement signal. Lateral support Keep plate Cable Pendular bearing Cylinder head OPERATING PRINCIPLE When force is applied to...
