INERTIAL-GRADE & REFERENCE
MEMS DC ACCELEROMETERS
SDI Q-Modules convert our Models 1525 and 1527 inertial-grade surface mount MEMS DC accelerometers into low-mass, low-power, electrically and mechanically compatible fixtures that can replace industry-standard quartz accelerometers within multiple inertial navigation applications. The Q-Modules offer direct pin and form factor compatibility, plus a wide operating temperature range, industrial-grade durability, and a low mass of just 5.6 grams.
SDI Model 2290 High-Precision MEMS DC Calibration Reference Accelerometers deliver inertial grade stability, as well as 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.. Their robust, plug-and-play design combines a simple 4-wire connection with SDI's own Model 1527 inertial-grade surface mount MEMS DC accelerometer chip for added convenience and performance accuracy within an industrial-grade module package. Each unit is 100% factory tested and calibrated before shipment.

INERTIAL MEMS ACCELEROMETER - ECCN 7A994
The Model 2225 Q-Module is a low-mass, low-power module, electrically and mechanically compatible with fixtures and equipment designed for industry-standard quartz accelerometers. It combines a high-temperature, open printed circuit board (PCB), specifically designed to give the high stability required for inertial applications, and SDI’s high-end industrial-inertial grade Model 1525 MEMS Accelerometer. The 2225 was designed to provide the high level of long-term stability required by intensive inertial-related applications for operation in -40 to +85°C environments, like backup systems for light to medium weight aircraft and helicopters.
Available in 5g, 10g, 25g, & 50g
PROVEN APPLICATIONS:

TACTICAL INERTIAL MEMS ACCELEROMETER - ECCN 7A994
The Model 2227 Q-Module is a low-mass, low-power MEMS inertial accelerometer, designed for inertial navigation and tilt applications requiring zero-to-medium frequency response. It features an industry-standard form factor and pin configuration that is directly compatible with traditional quartz inertial accelerometers. Model 2227 modules are assembled with a high-temperature, open printed circuit board (PCB), with a circuit that converts accelerometer differential output voltage into a level of current directly proportional to the amount of applied acceleration. This design allows the Model 2227 to achieve the necessary low-noise, high-stability, long-term repeatability and low power requirements of today's inertial navigation applications, at a competitive price point.
