The Model 6061 and 6062 Piezoelectric Accelerometers are ideal for vibration work with the advantage of small size and lightweight to minimize mass loading effects. They are designed for the measurement of wideband, moderate to high-level shock and vibration. The units incorporate an inverted shear crystal-mass assembly within a stainless steel body to provide a reliable sensor that is insensitive to environmental inputs such as base bending and thermal transients. Signal ground is connected to the outer case of the unit.
