CFT piezoelectric force transducers from HBM are available with measuring ranges from 5 to 120 kN enabling reliable, integrated force measurement, in particular where space is a constraint.

The transducers are suitable for monitoring highly dynamic press-fit and assembly processes with fast force variations. As part of the PACEline force measurement chain, CFT transducers can be used where uncalibrated force washers only could be used so far.

Minimal dimensions, absolute reliability: 97% less space required

The size of PACEline CFT piezoelectric force transducers is only 3% of the size of transducers using other sensor technologies. The very compact format however does not negatively affect reliability. CFT transducers measure over several intervals (decades) at consistent accuracy.

More benefits provided by PACEline CFT force transducers include high stiffness and rugged design required in particular for use in adverse industry environments. Thanks to the flange connection on both sides and a central bore, PACEline CFT force transducers can moreover be easily and quickly integrated into existing systems.

PACEline CFT force transducers are also available as CMC measurement chain including cable and charge amplifier.

Accessories and Cables


CSB4/1 summing box

Simplify the installation of piezoelectric sensors. The CSB4/1 summing box enables up to four piezoelectric sensors to be connected in parallel to an amplifier input. It can be fastened with screws and features electrical isolation of enclosure and sensor shielding.

Key Features

  • Force transducer with very compact design for compressive forces
  • Nominal (rated) forces: 5, 20, 25, 50, 70, 120 kN
  • High stiffness, rugged design
  • Suitable for press-fit and assembly applications with fast force variations
  • Stainless steel housing
  • Easy integration through flange connection on both sides and central bore
  • Output signal depends on applied force only, not on nominal (rated) force: High nominal (rated) force and high capability to withstand overload at identical output signal
