Triaxial load cells, piezoelectric force transducers Fx, Fy, Fz (Fz max up to ±450 kN / ±101 klbf) / 93X7-8C

Kistler offers force sensors, force links and dynamometers for NVH testing by application of Transfer Path Analysis (TPA).

93X7-8C

The triaxial load cells are piezoelectric force transducers for the exact measurement of all forces on the three orthogonal components acting in any arbitrary direction.
Main features / advantages
  • Accurate measurement independent of force application point
  • Load cells with wide frequency range
  • Easy installation
  • Force transducer in stainless, sealed sensor case
  • Rugged multipole plug connection

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 90x7 and 90x8 family measure all three components of the applied force in highest resolution. The three axis load cells in the 93x7 and 93x8 product family are optimally preloaded, calibrated and immediately ready to measure.

What differences exist between triaxial force transducers types 93x7 and 93x8?

The sensor types 93x7 and 93x8 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.
