Piezoelectric accelerometer BBVM-AS100

IEPEwith built-in electronicshigh-sensitivity

Product overview
The BBVM-AS100 is a top-exit IEPE piezoelectric accelerometer for industrial vibration and shock measurement. It features a PZT shear-mode sensing element, a hermetically sealed 316L stainless-steel housing and integrated IEPE conditioning for direct connection to constant-current vibration data acquisition and monitoring systems. The standard BBVM-AS100 provides 100 mV/g sensitivity and a ±50 g measurement range; alternative models cover high-g shock and high-sensitivity low-level vibration measurements.
