A1512 Accelerometer

A1512 Accelerometer

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 ±100g.
