Product BrochureProduct Datasheet

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 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.
