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.

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.

[post_content] => Magtrol’s MD-01 Transducers are designed for measuring static and dynamic compression loads. Using strain gauge technology, deformation of the sensing element provides an electrical signal proportional to the load or force being measured.
With quick single-screw mounting, this transducer can be easily integrated into wide array of applications.

The load cells of the ZC series have been designed for application in platform scales in the classes C1 to C3 according to OIML-RI 60 for platform sizes up to 600The load cells of the ZC series have been designed for application in platform scales in the classes C1 to C3 according to OIML-RI 60 for platform sizes up to 600 mm × 600 mm. They are made entirely of high strength low-hysteresis aluminum alloy with its outstanding measuring properties. The sensing element itself is a well-proven configuration of parallel benders. Metal-foil strain gauges transform the elastic deformation of the sensing element into a truly proportional electrical signal, which can be processed by an electronic weighing unit. The strain gauges are under a heavy-duty cover plate to protect them against climatic influences. As a standard, the load cells are equipped with a 1.5 m connection cable (different lengths or 6-wire connection are optional). In addition to the nominal loads given in the specification, intermediate load values can be delivered. It is a matter of course that these load cells, after calibration in N, can also be supplied as high-precision force transducers up to the accuracy class 0.05%. Due to their single-point configuration, these cells are largely insensitive to the off-center introduction of force. The load cells may also be supplied with an integrated amplifier (model ZC-E). Their electrical output can be chosen as either (0 to 10) V or (4 to 20) mA.

[post_content] => MAGTROL offers a wide range of Load-Force-Weight Transducers with optional integrated electronics or Load Monitoring Units (LMU) with B.I.T.E. functions creating an ideal measurement system which continuously checks for overloads and short circuits. Idealy for use on Safety Applications according to ECE-R10, ISO 13849-1 : CAT4 & PLe (LE 600 Series); ISO 13849-1 : CAT2 & PLd (LE 400 Series).
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.
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 full-bridge configuration. The positioning and orientation of the strain gauges have been optimized by means of the finite element method (FEM).
