PE Accelerometer Sensor, 150g, 1500m/s2

PE (charge output) accelerometers typically require a charge amplifier or a dynamic signal analyzer with charge input functionality. These sensors do not have an internal excitation power source, and their output is a high-impedance charge signal. This signal must be converted into a standard voltage signal using a matching amplifier before data acquisition and spectral analysis can be performed.

PE accelerometers are particularly suitable for high-temperature, high-frequency, or high-dynamic-range vibration testing, such as modal analysis of aerospace components, engine combustion vibration measurement, and material impact testing. They have strong anti-interference capabilities and can provide stable signal output in harsh industrial environments.

PE accelerometer sensors have pure charge output and require an external charge amplifier, making them suitable for complex or high-temperature environments. IEPE accelerometer sensors, on the other hand, have built-in charge amplifiers, making them convenient to use and requiring only a constant current source for excitation. The former is suitable for more demanding testing requirements, while the latter is suitable for portable or rapid deployment applications.
