Overview
The Bently Nevada Velomitor Piezo-Velocity Sensor is designed to measure absolute (relative to free space) vibration on bearing housings, casings, or structures. The 330500 model is a specialized piezoelectric accelerometer that integrates solid-state electronics for enhanced reliability and performance.
