Operating with Series 3991/3993 MEMS shock accelerometers, Model 478A30 provides MEMS-based shock measurement system with frequency range from dc to 150 kHz. Automatic zero adjustment eliminates sensor’s inherent DC offset voltage, while BNC output connectors enable hookup to readout and recording instruments. Offering differential output and gain adjustment from 0–999.9, device has 3 independent operating channels with selectable excitation voltage levels from 0–14 Vdc.
