Product Information ZwickRoell Xforce Dynamic load cell for Vibrophores Xforce Dynamic with mounting flange Xforce Dynamic: general layout drawing Range of application Load cells in the Xforce Dynamic range have been specially developed for use in dynamic testing machines and enable highly accurate measurement of tensile and compression forces under both static and oscillating/ fatigue loading. They are fatigue-resistant and suitable for alternating-load tests. measurement signal the sensors are arranged exactly in the force measurement plane. Description of operation Xforce Dynamic load cells have strain gages attached to the measuring body in accordance with the shear-web measurement principle. Their high stiffness and natural frequency make them the natural choice for dynamic applications. The accelerations occurring on load cells during dynamic tests, in combination with the connected masses, lead to distortion of the actual specimen force being measured. Xforce Dynamic load cells are there‐ fore additionally equipped with two accelerometers to compensate for the inertial forces which arise. As the two accelerometers have different measurement ranges, optimum matching of the acceleration measure‐ ment to the design/layout of the machine or to the test is possible. To avoid parasitic oscillations influencing the Xforce Dynamic load cells possess an intelligent EEPROM plug for connection to the ZwickRoell elec‐ tronics. All relevant load cell data, including calibration data, are stored on the plug, enabling the ZwickRoell testing software to identify the sensor automatically and among other things set the force limits accordingly. All mounting surfaces are in the form of a flange with centering spigot, ensuring alignment of the load string. Features • fatigue-resistant up to ±100% of nominal force • high natural resonance for use at high test-frequencies • inertial force compensation via two integrated acceler‐ ometers • high safety margin against overload • intelligent EEPROM plug with sensor data for simple connection to ZwickRoell electronics • 6-conductor technology for maximum measurement accuracy • flange adapter with centering spigot for
