DC Sensor Signal Conditioner features selectable gain.
April 22, 2008 -
Operating with Series 3991/3993 MEMS shock accelerometers, Model 478A30 provides MEMS-based shock measurement system with frequency range from DC-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 features 3 independent operating channels with selectable excitation voltage levels from 0-14 Vdc.

PCB Piezotronics Introduces 3-channel DC Sensor Signal Conditioner for New Series 3991/3993 High Amplitude 20,000 g MEMS Shock Accelerometers
Automatic Zero Adjustment Capability Eliminates Sensor's Inherent DC Offset Voltage
April 11, 2008, Depew, NY, USA - PCB Piezotronics (PCB®) has introduced Model 478A30, a 3-channel DC sensor signal conditioner with selectable gain. This model is designed to be compatible with new Series 3991/3993 high amplitude 20,000 g 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.
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. For detailed product specifications, drawings or additional information, please visit www.pcb.com.
