They can measure a wide frequency range, usually between 2 Hz and 15000 Hz and are compact and easy easily to mount. Accelerometers need an external power 

Piezoelectric Accelerometers. Piezoelectric accelerometers take advantage of the piezoelectric effect to measure dynamic changes in real world stimuli such as acceleration, vibration, and mechanical shock. While the broad base of vibration sensing applications can be covered by MEMS technology, certain cases where high dyanmic range, wide

Single axis and three axis (triaxial) accelerometer configuration parameters include sensitivity, temperature, frequency response, amplitude response, form factor and lead wire grounding. Accelerometers are critical for evaluating proper performance of equipment or structures.

The lower frequency limit of Metra´s transducers with integrated electronics is 0.1 to 0.3 Hz for most shear and bender accelerometers and 3 Hz for com- pression sensors. The upper frequency limit mainly depends on the mechani- cal properties of the sensor. In case of longer cables, their capacitance should be considered.

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 AM range of accelerometers are MEMS (micro electro mechanical system) DC response voltage output devices for testing at low frequency vibration measurement from DC (0Hz) and above.

Piezoelectric accelerometers can be used over a wide temperature range, but their charge/voltage sensitivities are temperature-dependent, which means impedance will occur

Applications. Major applications of piezoelectric accelerometers include: Engine testing - Combustion and dynamic stressing. Ballistics - Combustion, explosion, and detonation. Industrial/factory - Machining systems, metal cutting, and machine health monitoring. Original equipment manufacturer - Transportation systems, rockets, machine tools

Accelerometers are piezoelectric devices, that is, the primary sensing element is a piezoelectric element constructed in such a way that when stressed by vibratory forces, a proportional electrical signal is produced. The frequency response of an internally amplified ICP® accelerometer is described as the frequency range over which the
