Automated 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 “4-in-1” MDAC 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 afforded by the “4-in-1” MDAC helps 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.

System automation afforded by 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. The software control afforded by the “4-in-1” MDAC virtually eliminates operator error by ensuring repeatability, optimal signal-to-noise ratio, and reduced measurement uncertainty. It further removes operator adjustment requirements for gain, vibration levels, or other parameters. End-users also have the option of utilizing MB Dynamics’ own highly experienced software engineering services team to integrate “4-in-1” MDAC data exports into a customer-specified database.
