2518 SERIES SANDWICH LOAD CELLS

2518-1xx

Load cells are an integral part of the force measurement system of a testing machine. Their interchangeability along with transducer recognition and single-point electrical calibration makes them easy to use. They maintain high alignment and are resistant to offset loading throughout the test, even with large specimens. Instron® controls the design, manufacture and quality of all load cells, with customer applications in mind. They are certified in accordance with international standards for use in material testing machines only. 2518-100 Series load cells are fatigue-rated for use on Instron servohydraulic testing systems where high side-load resistance is desirable.

Principle of Operation 2518 Series load cells are precision force transducers containing a full bridge of strain gauges bonded to internal load bearing structures. When mechanically stressed, the electrical resistance of the gauges changes, thus changing the output signal. This signal is then conditioned for display readouts in accordance with international standards. The shear element design of the 2518-100 Series provides exceptional resistance to offset loads.

Application Range • Instron load cells have been tested for accuracy and repeatability on calibration apparatus traceable to international standards, with an uncertainty of measurement not exceeding one third of the permissible error of the load cell. Their accuracy is equal to or better than 0.025% of the cell rated output or 0.25% of the indicated load, whichever is greater. 2518 SERIES SANDWICH LOAD CELLS Catalog Number
