Filtered, Triaxial, ICP® Accelerometers

High frequency, metal-to-metal impacts can excite the high frequency resonance of the piezoelectric crystal in any accelerometer (PCB® or otherwise) to saturate the signal and cause clipping in the contained ICP® signal conditioning amplifier. Any system, once driven nonlinear, will produce spurious frequencies at, above, and below the frequencies contained in its input stimulus. If not recognized, this frequency production results in erroneous test data when it extends into the frequency range of interest.

To help alleviate this event, PCB offers low pass filtering in select triaxial accelerometers, which suppresses the effects of any crystal resonance before they can enter and over range the ICP signal conditioning amplifier. This prefiltering minimizes the opportunity for erroneous frequency content to be generated and accepted as valid data.

In addition to filtering, PCB Series 339A ICP Triaxial LTC accelerometers are designed with a temperature coefficient of less than 0.0125% / °F (0.02% / °C), which allows for precision amplitude data for test applications with large thermal shifts.
