The Model SC4601 IEPE Signal Conditioner is a portable/desk top low-noise signal Conditioner for use with integral electronics piezoelectric (IEPE) transducers or piezoelectric (PE) transducers when used with a remote charge converter (RCC). The unit provides the two wire constant current supply to the transducer /remote charge converter and signal amplification/filtering. Signal amplification (gain) is selectable as x1, x10 or x100 and the fixed frequency cut-off filter is selectable as IN or OUT. The unit is powered from an internal Lithium Ion (Li-ion) battery that can be recharged using the supplied charger. Led indicators are used to show the status of the battery, gain range selected, filter in and input status.
