For over 70 years, Magtrol has been providing professional solutions for a multitude of load, force and weight measurement applications. Based on our extensive know-how, we design and manufacture accurate and reliable load cells, as well as robust load and overload measurement systems for a wide range of applications. Our expertise has also led us to innovate transducers for specific fields, such as cable measurement (additional transducer) or miniaturization (cramped environments). Our commitment and knowledge enable us to offer high-quality, tailor-made solutions to meet the specific needs of our customers in a wide range of industrial sectors. LOAD MEASURING PINS LB & LE Series Load Measuring Pins are used to measure load and force and to 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 Load Pins are rugged with high resistance stainless steel and tight construction, designed specifically for use in hostile industrial environments. LB & LE Series Load Pins are used for load measuring devices and overload protection on cranes, hoisting gear, elevators, winches, and force measurement for regulation processes in industrial installations and machinery production. Moreover it is an ideal transducer to detect and measure forces in harsh, tropical, offshore, marine and harbor environments. 2 Fixed part Load Pin Keyway Moving Part Bearing Electronics F Main elements of a typical Load Pins monitoring application. datasheet product page Load Measurement Solutions CABLE SENSORS LMU Load Monitoring Unit The Cable Sensors are a cost-effective load cell specially designed for measuring tension force on hoisting ropes. Its easy installation does not require dismantling or modification of the hoist. The Cable Sensor family accommodates a wide range of cable diameters (ø8 ... 36 mm) corresponding to lifting loads for 8 kN to 150 kN. Reaction Force Combined with electronics (signal conditioner, display, etc.), the Cable Sensors from Magtrol form a complete measurement system, enabling loads to be continuously visualized and monitored, and overloads to be detected. SK-02 Cable Sensor Strain Gauge Sensor Recommended for ensuring the safety of industrial lifting installations, overhead cranes, winches, and hoists, the Cable Sensor is suitable for implementation on existing lifting systems. It facilitates compliance with current safety standards without requiring heavy modifications. datasheet product page F Typical installation of an SK-02 cable sensor on an overhead crane. THE REDUNDANT SYSTEM, AN ASSET FOR SAFETY The concept of redundancy in lifting systems refers to the use of devices that provide a second measurement solution in the event of failure of the first. Such systems guarantee continuity of operations and/or prevent potential dysfunction. Magtrol offers redundant force transducers which integrate two Full-Bridge Strain Gauges, thus providing two distinct signals. In the event of failure of one of the measuring bridges, this solution has the advantage of detecting an anomaly in the measurement chain and, if necessary, stop the process. Our complete range of LB and LE Series - Load Measuring Pins can be equipped with this technology to ensure safe operation of installations and thus increase their reliability. Applied Load DESIGN & OPERATING PRINCIPLE 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 full-bridge configuration. The positioning and orientation of the strain gauges have been optimized by means of the Finite Element Method (FEM). Reaction Force Reaction Force 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. The signal is then converted by the integrated electronics to a standard 4 ... 20 mA output. Based on SMD (Surface Mounted Device) technology, the electronics are well-protected against conducted and radiated electromagnetic fields. 3
