High-Performance Vibration Measurement for Casing and Structural Monitoring
The Bently Nevada 330881-28-04-110-03-02 Velomitor Piezo-Velocity Sensor is a rugged industrial vibration sensor designed to measure absolute casing vibration (velocity output) in rotating and reciprocating machinery. It belongs to the Velomitor piezo-velocity sensor family, widely used for machinery protection and condition monitoring in harsh industrial environments.
Unlike proximity probes that measure shaft relative vibration, the Velomitor sensor measures housing and structural vibration directly, making it ideal for applications where shaft access is limited or where casing vibration is the primary indicator of machine condition.
This model is commonly deployed in compressors, pumps, motors, fans, and turbines operating in continuous-duty environments.
