High-precision MEMS DC calibration reference accelerometers available now

19-07-2022 | Silicon Designs | Subs & Systems

Silicon Designs, Inc has launched its Model 2290 Series, a family of high-precision, single-axis MEMS DC calibration reference accelerometers.

Provided in four unique full-scale acceleration ranges of ±5g, ±10g, ±25g, and ±50g, the series provides a precise, reliable, and accurate means of determining the sensitivity and frequency response characteristics of unknown MEMS DC accelerometers through end-to-end calibrations and related performance verifications. Within these applications, Model 2290 works as the "Reference Standard," either for performance specification comparisons or as an actual substitute for the working accelerometer. Beyond such verifications, the series also supports various zero-to-medium frequency instrumentation applications ranging from 2000 Hz to DC, including centre of gravity acceleration measurements and equipment calibrations.

The rugged design of the series incorporates a high-precision, non-ITAR controlled, tactical-grade MEMS inertial sense element (US Export Classification ECCN 7A994) of similarly robust design to that which may also be found within the company's Model 1527 Series. The MEMS DC accelerometer chip and other internal components of the 2290 are housed within a 1" square, epoxy sealed, anodized aluminium case with a 10' integral cable. The cable further terminates into four-wire pigtails for seamless compatibility with most industry data acquisition systems. An initial calibration certificate is provided with each accelerometer. Units are REACH and RoHS compliant.

The series is relatively insensitive to temperature changes and gradients. Onboard voltage regulation and an internal voltage reference remove the requirement for precision power supplies. The anodised aluminium case is easily mounted with screws, adhesive, or a mounting magnet. As the reference accelerometer is non-ferrous, its performance stays unaffected by magnetic mounting techniques. Recommended optional accessories for the series, include the Model 2230 triaxial mounting block; Model 2232 magnetic mount; and Model 2235-BLK stud adaptor block.
