Bently Nevada 330505-01 – Low Frequency Velocity Sensor | 3300 Series Platform
Engineering Background
The Bently Nevada 330505-01 is a precision low-frequency velocity transducer engineered for continuous machinery health monitoring in rotating equipment applications. Designed as part of the industry-standard 3300 Series ecosystem, this sensor delivers reliable vibration signal acquisition in environments where conventional accelerometers lose sensitivity — particularly below 10 Hz.
Product Positioning
Targeted at maintenance engineers and reliability teams operating turbines, compressors, pumps, and fans, the 330505-01 integrates directly with Bently Nevada 3300 Series monitors and Orbit software platforms. It is the preferred choice for ISO 10816-compliant absolute vibration measurement on bearing housings and machine casings.

Proven Application Environments
- Steam and gas turbine bearing housing monitoring
- Centrifugal and reciprocating compressor casing vibration
- Large industrial pump and fan absolute vibration measurement
- Gearbox and motor end-shield low-frequency diagnostics
- Power generation plant continuous condition monitoring systems
- Petrochemical and refinery rotating machinery protection
Engineering Advantages
- Low-frequency sensitivity: Captures sub-10 Hz vibration signatures missed by standard accelerometers — critical for slow-speed machinery.
- 3300 Series native compatibility: Plug-and-play integration with existing Bently Nevada monitor racks, eliminating signal conditioning complexity.
- Absolute velocity output: Directly correlates to ISO 10816/20816 alarm thresholds without additional conversion.
- Robust industrial housing: Rated for harsh plant environments including moisture, dust, and vibration exposure.
- Proven field reliability: Widely deployed across global power generation and process industries for decades.
System Architecture & Signal Flow
The 330505-01 mounts on the machine casing or bearing housing and converts mechanical vibration into an analog velocity signal. This signal is routed via shielded cable to the Bently Nevada 3300 Series monitor rack, where it is conditioned, compared against alarm setpoints, and transmitted to the plant DCS or Orbit software for trending and diagnostics. The sensor operates as a passive seismic element — no external power supply required at the transducer head.

Technical FAQ
Q: Is the 330505-01 compatible with Bently Nevada 3500 Series monitors?
A: The 330505-01 is designed for the 3300 Series platform. Compatibility with 3500 Series requires signal conditioning verification — contact us for application engineering support.
Q: What is the difference between a velocity sensor and a proximity probe?
A: Velocity sensors measure absolute casing vibration (seismic); proximity probes measure relative shaft displacement. The 330505-01 is a seismic velocity transducer for bearing housing measurement.
Q: Can this sensor be used for low-speed machinery below 100 RPM?
A: Yes — the low-frequency design of the 330505-01 makes it suitable for slow-speed applications where standard sensors lose accuracy.
Q: Do you provide OEM warranty?
A: We offer a supplier-backed quality guarantee. OEM warranty terms depend on unit provenance — details provided at quotation stage.
Q: What is the minimum order quantity?
A: No minimum order quantity. Single units and bulk orders both accepted.
