This charge amplifier differs from the traditional voltage amplifier used in the past and converts the charge output from the piezo-electric pickup to physical quantities and measures them. This method eliminates the adverse influence of the pickup impedance as well as the static capacitance of the pickup cable,thereby permitting the use of a pickup of any cable length
-The vernier dial can readily calibrate the amplifier for a specific accelerometer sensitivity.
-Since there are four switching positions of cut-off frequency in both high-pass and low-pass filter, the analysis can be easily performed.
-Three output systems of AC, galvanometric and DC output accept all the recorders.
-A recorder can be easily calibrated with an internal calibration signal.
-It accepts both AC 100 V and DC 12 V input power.
