Single-axis accelerometer BBVM-RS100

piezoelectricIEPEshear

Product overview
The BBVM-RS100 is a single-axis IEPE piezoelectric accelerometer with a side-exit connection, engineered for vibration measurement where overhead clearance is limited or the cable must run parallel to the mounting surface. It uses a piezoelectric ceramic sensing element in a shear-mode design, a sealed metal housing and integrated IEPE signal conditioning. The standard model has 100 mV/g sensitivity and ±50 g range; additional sensitivity and high‑g options are available.
