330500-00-00 Bently Nevada Velomitor Piezo-Velocity Sensor for Casing Vibration Monitoring

The Bently Nevada 330500-00-00 Velomitor sensor is mainly used for absolute casing vibration monitoring. It has a solid-state structure, so there are no moving parts inside. For many industrial sites, it is installed on bearing housings of rotating equipment in non-hazardous areas.

Sensitivity: 3.94 mV/mm/s (100 mV/in/s) ±5%
The sensor output follows velocity changes from the machine, which helps with routine vibration checks.

Frequency Response: 4.5 Hz to 5 kHz (±3.0 dB)
Designed for vibration measurements across a wide operating frequency range.

Design & Isolation: 316L stainless steel, hermetically sealed
A sealed 316L stainless steel housing is used for stable operation in plant conditions.

Technical Note: Mounting torque must be 32-46 kg*cm to prevent false signals. Integrating this output to measure displacement is not recommended due to noise amplification.

Field Case: This base configuration (no adaptors/approvals) is widely deployed for casing vibration monitoring. It maintains signal integrity under up to 100% relative humidity.
