The REF TEK 147-01 Low Noise model provides excellent dynamic range useful when used with 24-bit digitizers like the REF TEK 130 Series. This accelerometer uses a state-of the-art force balance accelerometer which makes up for the mechanical characteristic limitations of conventional accelerometers. Using a force balance feedback sensor overcomes the shortcomings of nonlinear distortion and threshold of sensitivity of elastic measuring parts.
The 147-01/3 model shown here is +/- 4g full scale. The 147-01 high sensitivity, large linear range, high resolution, and high dynamic range make the 147-01 model best suited for free field applications such as microzonation, site response, earthquake monitoring, and more.
The 147-01 housing is sealed to meet IP67 standards for watertight integrity. Mounting is accomplished with a single bolt, 2 adjusting screws, and 3 point leveling. The 147-01 is available in uniaxial, triaxial and borehole housing.
