SDI 2290 HIGH PRECISION MEMS DC CALIBRATION REFERENCE ACCELEROMETER

The SDI Model 2290 Single-Axis MEMS DC Precision Reference Calibration Accelerometer offers a precise, reliable, and accurate means of determining the sensitivity and frequency response characteristics of unknown MEMS DC accelerometers during end-to-end calibrations and related performance verifications. Within these applications, the Model 2290 serves as the "Reference Standard," either for performance specification comparisons, or as an actual substitute for the working accelerometer.

​

In addition to calibration verifications, the Model 2290 Series supports a variety of zero-to-medium frequency instrumentation applications, ranging from DC to 2000 Hz, and including both center of gravity acceleration measurements and equipment calibrations. 

​

The SDI Model 2290 incorporates SDI’s hermetically sealed, low noise, Model 1527 MEMS DC Inertial-Grade surface mount accelerometer chip and SDI’s proprietary electronics for extra-low noise performance and inertial-grade stability.  The rugged, anodized aluminum, 1-inch square package provides all the same durability and reliability of SDI’s industrial accelerometers, along with the convenience of a 4-wire pigtail for seamless compatibility with almost any DAQ system.

​

The SDI Model 2290, as with the company's other MEMS DC accelerometer lines, is relatively insensitive to temperature changes and gradients. Onboard voltage regulation and an internal voltage reference eliminate the need for precision power supplies. The anodized aluminum case is epoxy sealed and is easily mounted via two screws, an adhesive, or by attaching it to a magnet.  The accelerometer is non-ferrous and will not respond to magnetic mounting.  An initial calibration certificate is provided with each unit.

​

The Model 2290’s US export designation is ECCN 7A994. It is not ITAR controlled.  

The SDI Model 2290 is both REACH and RoHS compliant.  ​
