Signal Processing Impacts of ICP Accelerometer Limit Violations - PCB
noise is caused by random fluctua ons in the resistor, primarily due to thermal effects. The noise is propor onal to R/f (resistance/frequency) and becomes more pronounced at lower frequencies.
VIBRATION FUNDAMENTALS - PCB
Piezoelectric accelerometers measure vibration and shock for a wide variety of applications. They incorporate a piezoelectric sensing element with a crystalline atomic structure which outputs an electrical charge when subjected to a load with near zero deflection.
Sensor overloading - Wilcoxon Sensing Technologies
Sensor overloading is a common cause of ski slope data and is simple to detect using the methods described below. A common problem in industrial vibration monitoring applications is sensor overload.
