MB Dynamics has released a “4-in-1” multi device-under-test (DUT) automated accelerometer calibration system.

The “4-in-1” MDAC facilitates simultaneous and accurate calibrations of up to four piezoelectric (charge or PE), IEPE (low-impedance voltage mode), or variable capacitive (VC) accelerometers (DUT's), of the same model and type, each weighing up to 20 grams, over frequencies from 1 Hz to 4000 Hz. The system can additionally perform automated single-DUT calibrations of PE, IEPE, velocity, piezoresistive and VC accelerometers, as well as vibration sensors and transducers, over frequencies from 1 Hz to 10 kHz, utilizing MB Dynamics’ own CAL50 calibration vibration exciter.

The automated multi-DUT capabilities help calibration technicians to effectively enhance productivity, reduce measurement uncertainty, and mitigate risks of operator error, by significantly reducing the amount of time required to calibrate multiple accelerometers within a single protocol. The “4-in-1” MDAC is further supported by MB Dynamics’ own proprietary Win475 software, along with an industry standard NI DAQ card. The software facilitates both single- and multi-DUT accelerometer sine calibrations with full NIST traceability and FFT processing at specified frequencies. It further allows for automated storage and retrieval of accelerometer data, test specifications, and calibration results.
