When is the piezoelectric measuring chain the better alternative?

Piezoelectric sensors offer unique advantages in many applications:

  • Where space is a constraint: Piezos are small and can be easily integrated.
  • When sensors are used with high initial load: 80 kN initial load - 500 N to be measured? Benefit from the option of short-circuiting the charge - irrespective of the force applied. When you perform a reset, no charge is applied. Select the electronics that provides the measuring range you actually need.
  • When extreme overload stability is required: Take advantage of the fact that the sensitivity and nominal (rated) force of piezoelectric sensors are unaffected by the load applied. Irrespective of whether you use a sensor with 20 kN or 120 kN - the output signal remains unchanged. If there is the possibility that high forces may occur, opt for 'one size larger' - without any adverse effects.
  • When extreme dynamics are required with small forces: When high dynamics are required, in particular with small forces, PACEline sensors are the right solution. Resonance frequencies well into the five-figure frequency range result in bandwidths that are required in your application.

Piezoelectric Sensors and Charge Amplifiers

PACEline - that's the name of HBM's line of force sensors, strain sensors and charge amplifiers based on piezoelectric technology.
