New Industry-Exclusive System Facilitates Simultaneous Automated Calibrations of up to Eight Piezoresistive Accelerometers and Single-DUT Vibration Sensors, Complying with SAEJ211 and SAE2570 Standards
MB Dynamics, Inc. (www.mbdynamics.com)(MB), field-proven industry experts in the design, manufacture and supply of vibration test systems and equipment, including buzz, squeak and rattle (BSR), steering, and suspension component test systems; modal exciters and amplifiers; automated calibration systems; dynamic controllers; transducer calibration systems; and engineering services, today announced the global market launch of its Win475 MULTI-DUT CRASH-CAL (MDCC) automated accelerometer calibration system, offering a measurable 70% time savings over single-DUT calibration methods.
The MB Win475 MULTI-DUT CRASH CAL (MDCC) system provides accurate, efficient, and simultaneous automated calibrations of up to eight piezoresistive accelerometers (DUT’s) of the same model and type, over a frequency range of 10 to 4000 Hz, complying with SAEJ211, SAE2570, and other global automotive industry test standards. Its versatile design further supports automated single calibrations of non-piezoresistive DUT’s, including piezoelectric, IEPE, voltage and velocity sensors, over frequencies from 5 Hz to 15 kHz.
As a complete turnkey system, the industry-exclusive design of the Win 475 MULTI-DUT CRASH-CAL automated accelerometer calibration system seamlessly integrates MB’s own Model CAL25AB air bearing shaker, together with its Model 407-8X multi-channel signal conditioner; MB 500VI power amplifier; and proprietary MB Win475 MULTI-DUT CRASH-CAL software and NI DAQ card.
Other included system components include an internal removable reference (REF) accelerometer with 100 mV/g sensitivity and usable frequency range to 15 kHz, traceable to national standards and ISO 17025; an eight-DUT test instrument mounting fixture (TIMF) adaptor plate; a single-DUT TIMF; a 475PCM module; a Windows 10 PC, monitor, keyboard and printer; a calibration accessory kit; user manuals; and system installation, start-up and training support.
The MB Win475 MULTI-DUT CRASH-CAL automated accelerometer calibration system automatically measures and saves relevant accelerometer characteristics, such as ZMO, Zin and Zout, as well as input & output impedance values. As a highly flexible system, an end-user can choose from among seven individual (six internal, one external) high-precision resistors for shunt calibration. The system also reads onboard sensor electronic identifications, such as 1-Wire Dallas ID memory chips or TEDS piezoelectric accelerometers (per IEEE 1451). The MB MULTI-DUT CRASH-CAL automated accelerometer calibration system may be further integrated into customer-specified databases for additional automation capabilities with reduced calibration data transference errors.
System automation mitigates the risks of human errors inherent to manual accelerometer calibration systems, thereby freeing up technicians for other measurement tasks. The increased frequencies of accelerometer calibrations afforded by the MB Win475 MULTI-DUT CRASH-CAL (MDCC) system can lead to improved test data quality and reduce measurement uncertainty. The system has proven especially useful within the crash test and automotive safety test laboratory environments, in applications where larger volumes of piezoresistive accelerometers are in use, therefore requiring more frequent recalibrations. In addition, the MB Win475 MULTI-DUT CRASH-CAL provides a number of value-added end-user benefits, including bottom-line cost savings, with its elimination of outsourced calibration service needs; implementations of more efficient and effective in-house calibration processes; and simplifications of internal record-keeping accuracy, further aiding in ISO audit compliance.
The Win475 MULTI-DUT CRASH-CAL automated accelerometer calibration system is also accompanied by full technical support, with in-house customer training provided by the 40-year calibration experts at MB.
