CFW Piezoelectric Force Washers: Capacities From 20 kN to 700 kN

PACEline CFW force washers are highly reliable sensors that deliver dependable results even in harsh industrial environments and are EMC-tested. A careful and precise production process ensures minimal non-linearity resulting in a wide measurement range from few newtons up to kilonewtons. Very high stiffness allows for a high fundamental frequency and makes the sensor the ideal solution for fast processes in research and production. The force washers’ internal diameters are in line with market standards, thus easy integration is guaranteed. HBM provides pre-stressing sets for pre-stressing of the CFW sensors. Please watch our tutorial video for an explanation of how to easily calibrate your sensor.

  • HBM accuracy class: 1
  • Capacity: 20 kN...700 kN

Fast and robust

  • High stiffness
  • Stainless steel and high degree of protection
  • Not affected by electromagnetic fields

Interference-free and reliable highly dynamic measurements can be taken in industrial environments, even under unfavorable EMC conditions

Easy to install

  • Compatible with standard screw connections
  • Practical accessories available
  • Charge amplifiers, tried and tested in industrial applications, even with higher IP65 degree of protection
  • Summing boxes and amplifiers, galvanically isolated from the test object to which they are installed

Convenient and easy mounting using the necessary accessories (pre-stressing of the sensors, summing boxes, etc.) , no need to use insulation washers or similar

Wide measuring range

  • All sensors have the same sensitivity; output signal depends only on the type of installation and the force applied
  • Outstanding linearity due to excellent mechanical quality
  • Low-drift measuring chains

All the sensors of the CFW series allow for measurement of few newtons, even with high initial loads being present; very low drift ensures reliable calibration.

Extensive range of accessories

  • Various cables
  • Summing boxes for connecting sensors in parallel
  • Prestressing sets for convenient installation
  • Coupling for extending the cable

You will find more information in the data sheet.
