The SDI Model 2290 Single-Axis MEMS DC Precision Reference Accelerometer combines industrial-grade durability with inertial-grade performance with a simple analog output.
The 2290 is available in four ranges from ±5g to ±50g and offers a precise, reliable, and accurate means of determining the sensitivity and frequency response characteristics of other 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.
