Multi-direction load cell (3 forces and the moments)

Further to consultation with a university institute wanting to analyse the different efforts and torques to which the seat and back of a wheelchair are subjected, SENSY has developed a multiaxial sensor.

mesure de force dans 3 directions et 3 moments

Customer specifications :

Forces to be measured :

  • Seat :
    • Fx = Fy = 1 kN
    • Fz = 2 kN
    • Mx = My = 100 Nm
    • Mz = 200 Nm
  • Back of the wheelchair :
    • Fx = Fz = 0,75 kN
    • Fy = 1,5 kN
    • Mx = Mz = 50 Nm
    • My = 100 Nm

Accuracy: ± 0.5 %

Dimensions :

  • Length = width between 200 and 250 mm
  • Thickness: 100 mm maximum

Weight: less than 5 kg

Output signals: -10..0..10 V

Sensor designed :

  • The outputs are produced by three connectors where the force and the moment are grouped for each direction.
  • Dimensions: 220 x 220 x 60 mm
  • Weight: 4.2 kg
