Silicon Designs offers reference accelerometers in four acceleration ranges

Single axis MEMS DC calibration reference accelerometers make up the Model 2290 series by Silicon Designs. They are offered in four acceleration ranges, namely ±5g, ±10g, ±25g and ±50g. They are used to determine the sensitivity and frequency response characteristics of unknown MEMS DC accelerometers during end-to-end calibrations and related performance verifications. 

The accelerometer serves as the “reference standard,” either for performance specification comparisons or as a substitute for the working accelerometer. Beyond such verifications, the Model 2290 series accelerometers also support a variety of zero-to-medium frequency instrumentation applications ranging from 2,000Hz to DC, including both centre of gravity acceleration measurements and equipment calibrations.

The rugged design of the Model 2290 series incorporates a non-ITAR (International Traffic in Arms Regulation) controlled, tactical-grade MEMS inertial sense element (U.S. Export Classification ECCN 7A994). The MEMS DC accelerometer chip and other internal components of the Model 2290 are housed together within a one inch square, epoxy sealed, anodised aluminium case with 10-foot integral cable. The cable further terminates into four-wire pigtails for compatibility with most industry data acquisition systems, said Silicon Designs. An initial calibration certificate is supplied with each Model 2290 accelerometer. Units are both REACH and RoHS -compliant.

The Model 2290 series is relatively insensitive to temperature changes and gradients, added the company. Onboard voltage regulation and an internal voltage reference eliminate the need for precision power supplies. The anodised aluminium case can be mounted via screws, adhesive or a mounting magnet. The reference accelerometer is non-ferrous which means its performance remains otherwise unaffected by magnetic mounting techniques. 

Optional accessories are available, including the Model 2230 triaxial mounting block, the Model 2232 magnetic mount and the Model 2235-BLK stud adapter block. 

All Model 2290 MEMS DC calibration reference accelerometers are designed, manufactured, performance-verified, and calibrated in-house at the company’s corporate headquarters and ISO9001:2015 certified R&D centre, located just outside of Seattle, Washington, USA.
