A2512 Amplified Accelerometer

A2512 Amplified Accelerometer

The A2512 amplified 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 uniaxial, biaxial, and triaxial configurations with ±2g, ±5g, ±10g, ±25g and ±50g sensitivity options. The sensors are made-to-order with your choice of cable length. A non-amplified version, the A1512, is also available for cable lengths under 300ft.

Each model can be installed very quickly and securely through the use of our various mounting options and accessories.
