Columbia Model 5624 Charge Amplifier has been designed for use with virtually all piezoelectric transducers to form various airborne vibration and shock data acquisition systems. It features small package size and extremely low power consumption.
The Model 5624 Charge Amplifier provides both Acceleration and Velocity outputs from an individual signal-conditioning amplifier. Acceleration may be measured from 5 Hz to 2,000 Hz at a fixed gain conversion rate of 1.0 mV/pcmb. The velocity transfer function is 387 mV/pcmb/sec referenced to 1.0 mV/pcmb at 61.4 Hz. The nominal slope is 6 dB/octave over the bandwidth of from 5Hz to 2,000 Hz. Direct power/signal ground isolation is provided via an internal DC to DC power converter. Consult the factory for customized versions of this instrument.
