Bently Nevada 330901-00-32-05-02-05 Velomitor Vibration Transmitter – 3300 Series Machinery Protection System
When a critical rotating machine — a high-speed compressor, a steam turbine, or a large pump — loses its vibration monitoring signal, the consequences are immediate and severe. Without accurate, real-time velocity data, plant operators are flying blind. Bearing failures go undetected, rotor imbalance escalates unchecked, and what begins as a minor mechanical anomaly can cascade into catastrophic equipment damage, unplanned downtime, and significant safety risk. The Bently Nevada 330901-00-32-05-02-05 Velomitor Vibration Transmitter exists precisely to prevent this scenario — delivering continuous, reliable vibration velocity measurement that keeps your machinery protection system fully informed at all times.
Within the Bently Nevada 3300 Series platform — the industry’s most widely deployed machinery protection architecture — the 330901-00-32-05-02-05 occupies a specialized and critical role. Unlike traditional eddy-current proximity probes that measure relative shaft displacement, the Velomitor transducer measures absolute casing velocity, making it the preferred solution for high-frequency vibration detection on machines where casing motion is the primary diagnostic indicator. Trusted by petrochemical plants, power generation facilities, and heavy industrial operations across six continents, this transmitter represents the gold standard in velocity-based condition monitoring.

Frequently Asked Questions
Q: What is the difference between the Bently Nevada Velomitor and a standard accelerometer?
A: The Velomitor is a piezoelectric velocity transducer that outputs a 4–20 mA signal proportional to vibration velocity (mm/s or in/s). A standard accelerometer outputs a charge or voltage proportional to acceleration (g). The Velomitor’s integrated electronics and current-loop output make it directly compatible with 3300 Series monitors without additional signal conditioning, whereas accelerometers typically require charge amplifiers or IEPE power supplies.
Q: Can the 330901-00-32-05-02-05 replace other Velomitor models in the 3300 Series?
A: Compatibility depends on the specific suffix codes, which define connector type, cable length, and sensitivity. Always verify the full part number against your existing system documentation or consult our technical team before substituting models.
Q: Do you provide calibration certificates with this transmitter?
A: We provide available documentation from the supply chain. For applications requiring traceable calibration to NIST or equivalent standards, we recommend engaging a certified metrology laboratory after receipt. We can recommend accredited partners upon request.
Q: What is the typical lead time for the 330901-00-32-05-02-05?
A: Lead time varies by current stock status. Please submit an RFQ for a real-time availability check. In-stock units typically ship within 3–5 business days from our warehouse.
Q: Is this product suitable for use in hazardous (Ex) areas?
A: The 330901-00-32-05-02-05 may carry ATEX/IECEx certification depending on the specific configuration. Please confirm the Ex rating from the product label and official Bently Nevada datasheet before installation in classified hazardous locations.
