THE A1521 ACCELEROMETER HAS BEEN DESIGNED FOR DYNAMIC STRUCTURAL TESTING IN

TOUGH FIELD CONDITIONS. THESE ACCURATE, RUGGED, AND FULLY WEATHERPROOFED

INTEGRATED MEMS SENSORS CAN BE USED FROM ZERO TO MEDIUM FREQUENCY APPLICATIONS

THAT REQUIRE LOW NOISE AND RELIABLE LONG-TERM STABILITY. AVAILABLE IN UNI, BI, AND

TRI-AXIAL VERSIONS, EACH MODEL CAN BE INSTALLED VERY QUICKLY AND IS AVAILABLE IN

RANGES BETWEEN ±2g AND ±100 g.
