Product overview
The BBVM-AS100 is a top-exit IEPE piezoelectric accelerometer designed for industrial vibration and shock measurement. It combines a PZT sensing element, a shear-mode design, a hermetically sealed stainless-steel housing, and integrated signal conditioning for direct connection to constant-current vibration acquisition and monitoring equipment. The standard model provides a sensitivity of 100 mV/g and a measurement range of ±50 g. Available configurations extend from high-g shock measurement to high-sensitivity, low-level vibration measurement.
