Introduction to Piezoelectric Accelerometers

Determining phase and amplitude relationships of vibration at various points on a structure permits modal modeling. The resulting modal model provides valuable information regarding system integrity and operating mode shapes.

Seismic vibration
Sensors are used for measuring ground, building, or bridge vibration on very large structures to detect structural changes caused by earthquakes, construction, mining activity, and large transportation vehicles.

Package testing
Measuring the shock experienced by a packaged product compared to the level of actual shock exposure allows determination of the effectiveness of a packaging material. Package testing can also be used to monitor vibration and shock that a product may experience during transport.

Shock
Accelerometers may be used to determine maximum impact acceleration levels experienced by vehicles and crash dummies. Shock accelerometers also measure shock exposure experienced by space vehicles and cargo during stage separation.

A wide variety of piezoelectric accelerometer configurations are available. Each method has its own particular advantages and disadvantages for different applications. Since selecting a sensor is not trivial, applications assistance from PCB field representatives or factory application engineers is available to assist with the selection process.
