Industrial, high frequency, piezoelectric accelerometer use piezoceramic in the annular shear mode and provide 10mV/g ®ICP / ®IEPE Acceleration AC output. They are used for modal testing or when very high frequency measurements up to 20 kHz are needed.
Note about old compression design accelerometer.
Compare to obsolete compression design, annular shear piezoelectric sensors feature better frequency response, improved base strain, lower noise, smaller size, thermal transient imunity and insensitivity to cable motion. Annular shear mode is also less susceptible to transverse vibrations and better immune to electronic saturation at high frequency.
