General Piezoelectric Theory | PCB Piezotronics
It is for this reason that piezoelectric sensors are so rugged and feature excellent linearity over a wide amplitude range. In fact, when coupled with properly designed signal conditioners, piezoelectric sensors typically have a dynamic amplitude range (ie: maximum measurement range to noise ratio) on the order of 120 dB.
Dynamic Strain Sensors and Accelerometers for Structural Testing
The most widely used sensor for measuring the response in a structural dynamic test is undoubtedly the accel- erometer. The accelerometer technologies used in dynamic tests can be divided into piezoelectric or M EMS types.
Guide to Dynamic Force Sensors - PCB
Measurements of dynamic oscillating forces, impact or high speed compression/tension under varying conditions may require sensors with special capabilities. Fast response, ruggedness, high stiffness, extended range and the ability to also measure quasi-static forces are standard features associated with PCB® quartz force sensors.
