HRL Series – Anchor Load Cell
Product Description
HRL Series load cells consist of a high quality stainless steel. This compact load cell is designed specifically for heavy duty use on construction sites and include load cells with a range of 600 … 3 000 kN. Special designs are available upon request. The attached shielded cable includes a water-proof connector with cap. Versions without the connector are available as an option. Cable lengths are customizable according to the installation requirements; for further information please contact us. The data collected from the strain gauge is proportional to the applied force. The signal is transmitted to the monitoring unit for amplification.

[post_content] => LB 200 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 (LMUs) constitute an ideal safe measurement system which continuously checks for overloads and short circuits.
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 200 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 from 2.5 kN to 1250 kN, these highly ergonomic pins can be used for either new or refitted installations and are adaptable to various conditions.
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. 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.

The force transducers of the ZF / ZF-S Series have been designed for the measurement of static and dynamic tensile and pressure forces; they are characterized by their low assembly height at a high measuring accuracy. The force is introduced on one side through a central tapped hole, the other side of the force transducer has to be fixed to a sufficiently rigid plane surface by means of 8 high-strength hexagonal socket-head bolts to be tightened with a defined torque. A strain gauge bridge converts the elastic deformation of the sensing element into an electrical signal that can be evaluated. Compensation and adjustment elements are used to set the required technical data. As a standard, the transducers are equipped with a 3 m connection cable, which has free ends on the other side.
