Description

The 3-component force sensor is mounted between two flang- es under preload. It is able to measure both compression and tensile forces in any direction. A force produces a proportional electric charge according to the piezoelectric principle. The simple, vibration-resistance design of the force link is very rigid in order to ensure a high natural frequency as required for highly dynamic force measurement. The outputs of the four force links are interconnected in the summing box to enable measurement of the three orthogonal forces F x, F y and F z as well as 6-component force and mo- ment (Fx, Fy, Fz, Mx, My and Mz) acquisition. The four sensors are mounted with ground isolation to largely rule out ground loop problems. The rustproof set is protected against entry of splashing water and coolant. Together with the connecting IP67 penetration. The summing box is available separately as Type 5447A. Multicomponent quartz force links measure simply, directly and very accurately.

Liability for consequential damage resulting from the use of Kistler products is excluded. Assembly The multicomponent force link set is first connected to the 4 sensor cables of the summing box and then mounted on the prepared top plate fabricated as directed in the instruc- tion manual. Four M12 Allen screws are then used to mount the fully assembled force plate on a flat, clean base plate. Uneven bearing surfaces induce internal stresses that substan- tially increase the loading on the individual force links and can increase crosstalk. The four mounting holes in the top plate are sealed with a protective lid (optional accessory). Once the set has been correctly assembled, the force plate is ready for immediate use without recalibration.

Liability for consequential damage resulting from the use of Kistler products is excluded. Size of Top Plate The top plate must have dimensions between 300x300 mm and 900x900 mm. The size of steel top plates chosen must not exceed 600x600 mm. A cable length of 0.5 m is sufficient for top plates up to 750x750 mm in size. For larger sizes the corresponding cable length has to be specified. Weight of Top Plate The weight of the top plate can be calculated from the dimen- sions as follows:

  • Weight of steel top plate L x B x H x 7,8 x 10 kg/mm
  • Weight of aluminum top plate L x B x H x 2,8 x 10 kg/mm X YZ 300 L 900 b bmin 50 min 50 aamin 50 min 50 300 B L Fig. 3: Size of top plate Thickness of Top Plate The thickness depends on the size, load and material of the top plate.

Measuring Ranges The maximum allowed measuring range of the force plate depends on the dimensions and material of the top plate and on the point of force application. The maximum measuring ranges applied for a point of force application within and no more than 100 mm above the sur - face of the top plate. -30 -20 -10 300 350 400 450 500 550 600 650 700 750 800 850 900 Top plate length L [mm] Force [kN] Fz_steel Fz_alu Fx,y_steel / alu Fz ; Fx,y_steel / alu 22, FyFxyFx += Fig. 5: Measuring ranges Natural Frequency A carefully mounted force plate of the recommended thickness achieves the following approximate natural frequencies. 200 400 600 800 1000 1200 1400 1600 1800 300 350 400 450 500 550 600 650 700 750 800 850 900 Top plate length L [mm] Natural frequency fn(i) [Hz] Steel Aluminum Fig. 6: Natural freqency

Measuring system See data sheet entitled Cables for Multicomponent Force Sensors, Dynamometers and Force Plates (1687B_000-545). Parallel Connection When assembling the force plate the four force links are me- chanically connected in parallel. The measurement signals (electric charge) of the four sensors are also connected in par- allel in the summing box. The summed signal corresponds to the algebraic sum of the individual forces. Calibration The multicomponent force link set is calibrated in the fac- tory with a 300x300x35 mm steel top plate. Depending on the chosen size of top plate, the sensitivity of the three force components Fx, Fy and F z can deviate up to ±2 % from the calibrated value. Measurement Signal Conditioning A multichannel charge amplifier is required to complete the measuring system. It converts the measurement signals into an electrical voltage. The measurement is exactly proportional to the acting force. Multichannel charge amplifier Type 5080A... has been manufactured specifically for multicomponent force measuring systems.
