- What is accelerometer’s nominal sensitivity?Nominal sensitivity of an accelerometer defines the deviation specification in what is considered acceptable sensitivity range. For example: if sensitivity is of an accelerometer is defined as +-)
- What is the difference between an IEPE sensor and a charge sensor?An IEPE sensor includes built-in electronics while a charge sensor does not. As a result, an IEPE sensor can convert the high-impedance output charge signal to a low-impedance voltage signal within th)
- What is transverse sensitivity?Transverse sensitivity is the sensitivity (in percentage) of a uni-axial sensor to a perpendicular acceleration within a specified frequency range.)
- What is discharge time constant?Discharge time constant is the measurement of time that it takes for the signal to decay 63%. The higher the discharge time constant, the slower the signal is bled off and hence the better the l)
- What is resonant frequency?Resonant frequency is the frequency at which the sensor tends to vibrate with greatest amplitude. Every item in the world inherently has its own resonant frequency based on its mechanical constr)
- What is frequency response?The frequency response is the frequency range over which the sensor will provide a linear response. The upper end frequency response is determined by the sensor’s resonant frequency and the low end fr)
- What are the main materials used to manufacture piezoelectric elements?Quartz and lead zirconate titinate (ceramic) are the two most common materials used in the manufacture of piezoelectric elements. Quartz sensors offer high voltage sensitivities and require voltage am)
- What can piezoelectric sensors measure?Dynamic measurements (ie. measurements rapidly changing over time). Piezoelectric sensors cannot measure static measurements because the crystals of a piezoelectric pressure sensor generate a charge w)
