BENTLY NEVADA 330750-40 High Temperature Velomitor Transducer – 3300 Series Machinery Protection System
Imagine a critical rotating machine — a high-speed compressor, a steam turbine, or a petrochemical pump — operating at the edge of its thermal envelope. The bearing housing temperature climbs past 120°C. A standard accelerometer would have already failed silently, leaving your machinery protection system blind at the exact moment it matters most. Without a sensor rated for extreme heat, the first warning you receive is not an alarm — it is a catastrophic mechanical failure, unplanned downtime, and a repair bill that dwarfs the cost of the sensor itself. The BENTLY NEVADA 330750-40 High Temperature Velomitor System exists precisely to prevent this scenario.
Within the Bently Nevada 3300 Series — the global benchmark for continuous machinery protection — the 330750-40 occupies a specialized and critical niche. It is an integrated circuit piezoelectric (ICP®-compatible) velocity transducer engineered to deliver accurate, low-noise vibration velocity signals in environments where ambient and surface temperatures would destroy conventional sensors. Trusted by rotating equipment engineers across oil & gas, power generation, and heavy industry worldwide, the 330750-40 is a direct-mount, high-reliability solution that integrates seamlessly into Bently Nevada monitoring racks and third-party vibration monitoring systems alike.

Key Features & Benefits
- High-Temperature Rated Design: Purpose-built for bearing housings and machine surfaces where standard sensors fail — maintains signal integrity at elevated ambient temperatures.
- Velocity Output for Direct Severity Assessment: Velocity (mm/s or in/s RMS) is the ISO 10816 / ISO 20816 standard measurement for vibration severity — no additional integration circuitry required.
- Low Noise, High Sensitivity: ICP® architecture delivers a clean, low-impedance output signal resistant to electromagnetic interference (EMI) common in industrial environments.
- Plug-and-Play with 3300 Series Racks: Designed for direct integration with Bently Nevada 3300 Series monitors, minimizing commissioning time and configuration complexity.
- Rugged Industrial Construction: Stainless steel housing, hermetically sealed internals — built to withstand vibration, moisture, and chemical exposure in harsh plant environments.
- Long Service Life: Solid-state design with no moving parts ensures years of maintenance-free operation, reducing total cost of ownership.
Industry & Equipment Applications
- Oil & Gas: Upstream compressors, gas turbines, pipeline pumping stations — where high ambient temperatures and continuous operation demand the most reliable sensors.
- Power Generation: Steam turbines, gas turbines, boiler feed pumps — critical assets where unplanned outages carry enormous financial and safety consequences.
- Petrochemical & Refining: Process compressors, reactor agitators, hot-service centrifugal pumps operating near heat sources or in high-ambient areas.
- Pulp & Paper / Heavy Industry: Dryer section rolls, kiln drives, and other rotating equipment in thermally demanding environments.
- Marine & Offshore: Engine room machinery and propulsion systems where space is limited and temperature extremes are routine.
System Integration & Compatible Parts
The 330750-40 is designed as a field element within the Bently Nevada 3300 Series Machinery Protection System. Typical system architecture includes:
- 3300/16 Dual Velocity Monitor — primary rack-mount monitor for velocity channel processing
- 3300/55 Keyphasor® Module — for phase reference and 1X/2X vector analysis
- 3500 Series Monitors — for installations requiring the newer platform with the same Velomitor sensor family
- Interconnect Cables (330130 / 330180 series) — Bently Nevada armored extension cables for signal integrity over long runs
- Junction Boxes & Barriers — for IS (intrinsically safe) installations in hazardous areas

Frequently Asked Questions
Q: What is the difference between the 330750-40 and a standard Velomitor (e.g., 330750-00)?
A: The 330750-40 is the high-temperature variant of the Velomitor family, rated for elevated ambient and surface temperatures that would degrade or destroy standard-temperature versions. The suffix “-40” denotes the high-temperature configuration within Bently Nevada’s part numbering system.
Q: Is the 330750-40 compatible with the Bently Nevada 3500 Series?
A: Yes. The Velomitor sensor family is compatible with both 3300 and 3500 Series monitors. Verify the specific monitor card’s input configuration with your system documentation or contact our team for assistance.
Q: Can I use this sensor in a hazardous (Ex) area?
A: The 330750-40 may be used in hazardous areas when installed with appropriate intrinsic safety barriers or Zener barriers. Consult the Bently Nevada system safety manual and your local regulatory requirements before installation.
