What is a piezoelectric force sensor?

The piezoelectric force sensor, also known as a load washer or measurement washer, is the classic piezoelectric measurement element for the measurement of force along a single axis. It describes either a compression or tensile force Fz or a shear force Fx,y. 

How are piezoelectric force sensors used?

Piezoelectric force sensors are normally integrated at the measuring point directly in the force flux of the existing structure and installed and calibrated with the required pretension.

Pretensioned piezoelectric force sensors or force transducers are immediately ready to perform measurements and are delivered calibrated. They can be used to measure compression and tensile forces.

Piezoelectric force sensors are used in various applications, for example, in mounting technology, in spotwelding or in presses, during the measurement of impact resistance, cutting forces and forming forces or in force plates, Weigh In Motion systems and in crash-test setups.

What advantages do 1-component force sensors offer?

  • High stiffness and, as a result, high natural frequency
  • High loading capacity
  • Durability at high cyclic loading
  • Large measuring range
  • Extremely compact design

Strain Sensors

Piezoelectric strain sensors from Kistler can be used for high-resolution measurements of the strains occurring on a structure. To achieve this, the sensor is mounted in a suitable position. If an indirect force measurement is required, the sensor is calibrated. Surface strain sensors are attached to the structure with the mounting screw. The structure’s strain is transmitted to the measuring element through static friction. Strain measuring pins need a cylindrical mounting bore in which the strain sensor is then inserted and preloaded. Kistler offers piezoelectric strain measurement sensors with axial and radial alignment to the axis of the bore hole.
