Piezoelectric accelerometers

These sensors are based on the piezoelectric effect, where an input acceleration causes a force on the seismic mass which leads to a proportional charge generation within the ceramic PZT material. (The IEPE (integrated electronics piezo electric) circuitry features the conversion of the charge to an analog voltage output signal. As opposed to capacitive accelerometers this signal has a high-pass characteristic, which enables highly dynamic measurements with a very high bandwidth of up to 16 kHz (±10 %) even without the detection of static DC components. Other advantages of piezoelectric accelerometers are high operating temperatures of up to +150 °C and a large selection of different measurement ranges from ±16 g to ±2,000 g.

In this category, ASC offers both uniaxial and triaxial accelerometers. The compact and lightweight versions are used for test and measurement applications, such as structural and modal analyses, while the robust versions are ideal for all industrial applications such as continuous condition monitoring of machinery and equipment.
