Hioki 8947 Charge Unit

2 ch, Charge-output type piezoelectric acceleration pick-up sensor, Acceleration pick-up sensor with an internal preamp. The CHARGE UNIT 8947 is equipped with circuits for two independently usable input channels. As with previous analog units, simply slot the 8947 into the MEMORY HiCORDER for use.

• In addition to its charge input terminals, the 8947 is equipped with BNC terminals that support internal pre-amplifier pickup sensors
  Not only ordinary piezoelectric acceleration pickups, but voltage output acceleration pickups with internal pre-amplifiers can be connected directly to the 8947, which supplies a constant current power supply for pre-amplifier operation.
• Accommodates voltage signal inputs
  In addition to acceleration pickup signals, the 8947 can also measure ordinary voltage signals.
• Internal anti-aliasing filter
  The 8947 is equipped with an anti-aliasing filter that is indispensable when performing FFT analysis on vibration waveforms.
• The 8947 can be used for the following applications:
  Measuring engine vibration, Measuring brake vibration, Measuring pump vibration, Measuring bearing vibration, Measuring vibration of vibrators in cellular telephones, CD player vibration testing … and other types of vibration endurance testing
