April 13, 2008, Depew, NY, USA – PCB Piezotronics (PCB) introduced Model 478A30, a 3-channel DC sensor signal conditioner with selectable gain. This model is compatible with Series 3991/3993 high amplitude 20,000 g MEMS DC response shock accelerometers, providing the end user with a MEMS-based high-g shock measurement system, with frequency range from DC to 150k Hz.The significant feature of this device is its automatic zero adjustment capability for elimination of a sensor’s inherent DC offset voltage. Model 478A30 features three independent operating channels with individual excitation voltage, selectable excitation voltage levels from 0-14 VDC; 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 & 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. Model 478A30 is also a stock product, available for expedited delivery.
