Silicon Designs has added more g-ranges and end-user enhancements to its Model 2227 MEMS inertial accelerometer series. Initially launched as a strictly ±25-g product, the Series is now offered in both ±10 g and ±50 g ranges, respectively. In addition to its direct drop-in replacement compatibilities, Model 2227 Series units now include an integrated adjustable scaling factor that allows end-users to achieve greater accelerometer voltage output flexibility, at any specified g-range, of as much as 25%.
Overall design of the series combines two patented capacitive silicon sense elements and a precision, custom CMOS integrated circuit. The elements and circuit are housed together within a compact, low mass, hermetically sealed LCC package. Modules are assembled on a high-temperature open printed circuit board (PCB) with a circuit that converts the MEMS accelerometer differential output voltage into a level of current directly proportional to the amount of applied acceleration. Final testing is conducted on a temperature-tumble-system, ensuring thermal calibration parameters that simplify accelerometer use with the user’s own real-time temperature compensation and modeling software.
