Description
The Bently Nevada 330500-03-00 Velomitor utilizes an integrated solid-state design to measure absolute bearing housing, casing, or structural vibration. By combining a piezoelectric accelerometer mechanism with onboard integrating electronics, this rugged sensor converts acceleration directly into a high-fidelity velocity output signal over a standard 2-pin interface.

Part Number Breakdown and Option Codes
The specific model suffixes dictate physical mounting styles and regulatory compliance profiles. Ensure these options align with your structural tapping points before completing procurement.
- Base Model (330500): Velomitor Piezo-Velocity Sensor
- Mounting Thread Adapter Option (-03): Includes a 1/4 – 28 UNF thread adapter profile
- Agency Approval Option (-00): No regional hazardous area approvals required (Standard industrial environments)
Technical Specifications and Operating Limits
Because the Velomitor contains no moving parts, it eliminates the mechanical wear issues inherent to traditional moving-coil velocity transducers. It can be bolted vertically, horizontally, or at intermediate angles.

Field Commissioning and Vibration Analysis Notes
Where should this sensor be deployed for the best diagnostic clarity on a large pump assembly? Solid-state velocity tracking shines brightest on machines utilizing rolling-element bearings. However, if you attempt to integrate the 330500-03-00 output down into displacement metrics within your 3500 monitoring rack, low-frequency electrical interference can easily skew the math. Well, technically it handles raw velocity monitoring down to 4.5 Hz smoothly, but processing that into mil-scale displacement will amplify thermal drift and trace circuit noise, leading to phantom machinery trip alerts.
Pay close attention to structural installation torque values during field mounting. Over-tightening the sensor into the tapped hole will distort the internal piezoelectric crystal assembly, creating signal drift. Torque the sensor casing strictly between 24 and 40 in-lb (approximately 32 to 46 kg-cm). Check that the mating surface is completely machined flat and free of burrs; uneven seating introduces high-frequency mechanical resonances that look like a failing bearing cage to your automated diagnostics.
Global Trade, Shipping Terms, and Supply Chain Routing
Delivering machinery health monitoring assets across international trade networks requires transparent regulatory data to bypass border holding areas.
- Incoterms Options: We process standard export operations via FCA (Free Carrier) or EXW (Ex Works) protocols out of our international hubs. If a critical turbine or generator line is down, we can deploy DDP (Delivered Duty Paid) shipping to clear local port duties and import handling lines automatically.
- Customs Filing Metrics: The commercial packing invoice lists the correct classification code (HS Code: 9031.80 — Measuring or checking instruments, appliances, and machines). Since this item features standard industrial vibration logging parameters with the -00 non-hazardous option code, it moves through customs without specialized dual-use import licensing.
- Freight Packaging Standards: Piezoelectric crystals are shock-sensitive until bolted down to a heavy structure. We ship each Velomitor wrapped in custom shock-absorbing padding inside a rigid outer container designed to handle up to 5,000 g drop impacts without degradation of the factory calibration.
