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. Independent of the point of force application, the load cells with the installed triaxial force transducers of the 90×7 and 90×8 family measure all three components of the applied force in highest resolution. The three axis load cells in the 93×7 and 93×8 product family are optimally preloaded, calibrated and immediately ready to measure.

What differences exist between triaxial force transducers types 93×7 and 93×8?

The sensor types 93×7 and 93×8 differ only in the position of the connector in relation to the coordinate system (inverted orientation of the x and y axes). The technical specifications of both types are identical.

How do I get a Certificate of Conformity (CE-Label) for triaxial load cells or piezoelectric force transducers?

According to the exception to Directive 2014/30/EU (EMC Directive) for piezoelectric sensors, piezoelectric force transducers, or so called also triaxial load cells, do not need a certificate of conformity.

Piezo-electric sensors without electronics, manufactured by Kistler, are covered by the exception mentioned under article2, section 2d. Therefore, these sensors neither need a CE-Logo nor a certificate of conformance.
