Product Description
The Bently Nevada 330500-02-04 Velomitor Piezo-velocity Sensor is engineered to monitor absolute vibration levels on bearing housings, casings, or structural elements of rotating machinery. Utilizing solid-state piezoelectric accelerometer technology with embedded electronics, it offers enhanced reliability with no moving parts. This sensor is suitable for installations in various orientations and harsh industrial environments.
Applications
-
Vibration monitoring of turbines, compressors, motors, and pumps
-
Detecting mechanical faults like imbalance and misalignment
-
Integration into predictive maintenance systems
-
Machine casing or bearing housing vibration assessment
-
Use in hazardous areas with certified versions
Key Advantages
