Bently Nevada 330400-02-05 Velomitor Sensor

The Bently Nevada 330400-02-05 Velomitor sensor represents a specialized class of piezoelectric velocity transducers. Unlike standard accelerometers, this device integrates internal electronics that perform onboard integration to provide a velocity output directly. This capability makes it exceptionally effective for monitoring casing vibration on a wide variety of rotating equipment, including pumps, motors, and fans. By capturing vibration in the velocity domain, the sensor provides a more balanced view of machine health across the most critical frequency ranges, allowing maintenance teams to identify structural resonances and mechanical looseness with higher clarity.

Technical Specifications and Hardware Configuration

The 330400-02-05 variant features specific mounting and connector options tailored for standard industrial installations. The following table details the primary physical and electrical characteristics:

Performance in Aggressive Industrial Environments

To ensure survival in the most demanding field conditions, Bently Nevada utilizes 316L stainless steel for the sensor housing. This hermetically sealed design protects the internal piezo-ceramic element from moisture ingress and corrosive chemical exposure. Furthermore, the 330400-02-05 operates effectively across a broad temperature range, which is vital for assets in the oil and gas and power generation sectors. Because the sensor does not contain moving parts—unlike older moving-coil velocity transducers—it resists mechanical wear and maintains calibration stability even under continuous high-vibration exposure.
