This triaxial load cell is a piezoelectric force transducer for the exact measurement of all forces on the three orthogonal components acting in an arbitrary direction. Independent of the point of force application, the load cells with the installed triaxial force transducers of the 90x7 family measure all three components of the applied force in highest resolution. The three axis load cells in the 93x7 product family are optimally preloaded, calibrated and immediately ready to measure. The triaxial load cells are mounted under preload between two plates and measure both tensile and compression forces in all directions. Based on the piezoelectric principle, a force produces a proportional electric charge. This is conducted via an electrode to the appropriate connector. The simple and vibration-resistant design of the force transducers is very rigid resulting in a high natural frequency, which is a requirement for highly dynamic force measurements. The 3-pole connector V3 neg. (design protected) is provided with a positioning aid. This guarantees accurate assignment and centering of the connector pins and sockets before connection. The plug connection is protected against rotation. After correct installation, the load cell is ready for use without recalibration. Triaxial force transducers allow simple, direct and very precise measurements.
