Uniaxial & Triaxial Accelerometer
The 147A Low Noise Accelerometer uses a state of the art force balance feedback technique to improve performance characteristics over conventional accelerometers.
It is +/-4g full scale and has excellent dynamic range. Make the most of the dynamic range available by combining it with a 24-bi digitizer such as the Wrangler and the 130-MC Recorder.
The 147A High Resolution Accelerometers are a force‑balance accelerometer that converts acceleration signals into voltage signals to measure various low frequency and ultra-low frequency motion. The 147A accelerometer is available in both triaxial and uniaxial packages.
The 147A accelerometer force balance feedback technique overcomes the shortcomings of nonlinear distortion and threshold of sensitivity of elastic measuring parts. The advanced features of the 147A accelerometer include high sensitivity, large linear range, high resolution, and high dynamic range. The 147A accelerometer has DC response.
High sensitivity, large linear range, high resolution, and high dynamic range make the 147A model best suited for free field applications such as micro zonation, site response, earthquake monitoring, and more. The 147A housing is sealed to meet IP67 standards for watertight integrity. For the triaxial package, mounting is accomplished with a single bolt, and 3 point leveling.
