PIEZOTITE® Shock Sensor | 3] - Q + 3. eS The piezoelectric element produces a voltage which is proportinal to the acceleration of an impact or a vibration to which it is exposed. The shock sensor utilizes piezoelectric ceramics to convert the energy of impact into a proportional | electrical signal. The piezoelectric shock sensor uses a “unimorph” diaphragm which consists of a piezoelectric ceramic disk laminated to a metal disk. The diaphragm is supported along its circumference in a housing. The sensor features compact, lightweight design, and is suitable for a | wide range of applications requiring impact and vibration | sensing.
FEATURES
