Found naturally in quartz and synthesized in special ceramics, the piezoelectric effect is the phenomenon that an electrical charge is produced as a result to a stress applied to the material. PE accelerometers utilize this technology by mounting an Meggitt Sensing Systems has announced the Endevco model 7251A series, a family of small, lightweight, hermetically sealed piezoelectric accelerometers with integral electronics. The centrally located thru-bolt mounting hole of this series provides both 360 Although piezoelectric devices have a mature user-base, MEMS accelerometers offer easy integration and reduced cost to an emerging group of new users. In addition, their advanced functional integration allows devices – such as Analog Devices’ ADIS16229 Despite its humble appearance, the accelerometer consists of many different parts and works in many ways, two of which are the piezoelectric effect and the capacitance sensor. The piezoelectric effect is the most common form of accelerometer and uses A compact, plug-and-play piezoelectric accelerometer from Measurement Specialties, the Model 8101, is designed for general purpose vibration measurement. The linear accelerometer is available in two dynamic ranges, ±40 g and ±160 g, and can be used in San Juan Capistrano, California, USA - Meggitt Sensing Systems, a Meggitt group division, has announced the global market introduction of the Endevco® model 2228C, a rugged low-mass triaxial piezoelectric accelerometer, designed to suit a variety of .

SAN JUAN CAPISTRANO, Calif., 23 April 2012. Meggitt Sensing Systems in San Juan Capistrano, Calif., is introducing the model 2220E miniature piezoelectric accelerometer for high-temperature vibration measurements in applications such as aircraft engine Equally prevalent is the use of piezoelectric accelerometers to satisfy application requirements. These types of sensors allow an engineer to collect the necessary real-time data to make smart design modifications at the prototype stage, ultimately saving The Endevco® model 7257AT is a compact, hermetically sealed piezoelectric accelerometer with integral electronics for vibration measurements on flight test vehicles, particularly ones that incorporate telemetry as their chosen data acquisition system. Now available from Bestech Australia, the lightweight Endevco model 2225 and 2225M5A piezoelectric accelerometers are designed specifically for measuring high G shock on structures and test articles and are considered by many users to be the industry .
