Silicon Designs, Inc., announced the global market release of its Model 2290 series, a family of high-precision, single-axis MEMS DC calibration reference accelerometers.

Available in four unique full-scale acceleration ranges of ±5 g, ±10 g, ±25 g and ±50 g, the series offers a precise, reliable and accurate means of determining the sensitivity and frequency response characteristics of unknown MEMS DC accelerometers during of end-to-end calibration and related performance checks. In these applications, the Model 2290 serves as a “Reference Standard” either for comparisons of performance specifications or as an actual replacement for a working accelerometer. In addition to such checks, the series also supports a variety of zero- to medium-frequency instrument applications ranging from 2000 Hz to DC, including both center-of-gravity acceleration measurements and equipment calibration.

The rugged design of the Model 2290 Series features a high-precision, non-ITAR controlled, tactical-grade MEMS inertial sensing element (US Export Classification ECCN 7A994) with a similar rugged design to that found in Silicon Designs’ own industry best-selling model 1527 series. The MEMS DC accelerometer chip and other internal components of the Model 2290 are housed together in a 1” square, epoxy-sealed, anodized aluminum case with a 10-foot built-in cable. The cable is additionally terminated with 4-wire pigtails for seamless compatibility with most industrial data acquisition systems. An initial calibration certificate is supplied with each Model 2290 accelerometer. The devices are REACH and RoHS compliant.

The Model 2290 Series is relatively insensitive to temperature changes and gradients. Built-in voltage regulation and internal voltage reference eliminate the need for precision power supplies. The anodized aluminum body mounts easily using screws, glue or a mounting magnet. Since the reference accelerometer is made of non-ferrous metals, its performance remains unaffected by magnetic mounting techniques. Recommended additional accessories for the Model 2290 series, also available from Silicon Designs, include the Model 2230 triaxial mounting block; Model 2232 Magnetic Stand; and Model 2235-BLK stud adapter block.

All Model 2290 high-precision, single-axis, MEMS DC calibration reference accelerometers are designed, manufactured, performance-tested and calibrated in-house at the company’s own global corporate headquarters and ISO9001:2015-certified R&D center located just outside of Seattle, Washington. USA. Silicon Designs is also a 100% US-based, veteran-owned small business.
