PCB Piezotronics introduced Model 478A30, a three-channel DC sensor signal conditioner with

selectable gain. This model is designed to be compatible with new Series 3991/3993 high

amplitude 20,000g MEMS DC response shock accelerometers, and providing the end user with a

MEMS-based high-g shock measurement system, with frequency range from DC to 150k Hz. It

features automatic zero adjustment capability for elimination of a sensor’s inherent DC

offset voltage, three independent operating channels with individual excitation voltage,

selectable excitation voltage levels from 0V to 14V DC; differential output and gain

adjustment from 0 to 999.9, as well as BNC output connectors, for easy hookup to readout and

recording instruments. The unit may also be used with Series 3741 DC response

accelerometers. Common applications for a high amplitude measurement system which includes

Series 3991/3993 and the accompanying Model 478A30 DC sensor signal conditioner include

fuze/safe and arm testing applications; drop testing; consumer electronic products testing;

metal-to metal-impacts; penetrator tests, blast loading of structures; weapons data recorder

testing; and crash and impact testing.
