Bently Nevada 24701-33-05-00-024-04-02 – Proximity Probe Housing Assembly | 3300 XL Series Platform
Engineering Background: The Bently Nevada 3300 XL Series represents the industry benchmark for continuous shaft vibration monitoring in rotating machinery. Developed by Baker Hughes (Bently Nevada), this platform is deployed globally across power generation, oil & gas, petrochemical, and heavy industrial facilities where unplanned downtime carries catastrophic operational and financial consequences.
Product Positioning: The 24701-33-05-00-024-04-02 is a precision-engineered Proximity Probe Housing Assembly designed to mechanically protect and accurately position the eddy-current proximity probe tip relative to the rotating shaft. It ensures consistent gap distance, shields the probe from process fluids and mechanical interference, and maintains signal integrity under extreme thermal and vibration loads. This assembly is a critical field-replaceable unit (FRU) for maintenance engineers performing scheduled overhauls or emergency replacements on 3300 XL monitoring systems.

Proven Application Environments
- Power Generation: Steam turbines, gas turbines, and hydro generators — continuous shaft radial vibration and axial position monitoring per API 670.
- Oil & Gas: Compressor trains, centrifugal pumps, and expanders in upstream/midstream/downstream facilities with hazardous area classification.
- Petrochemical & Refining: Critical rotating equipment where API 670 compliance is mandatory for insurance and regulatory purposes.
- Marine & Offshore: Propulsion shaft monitoring in high-humidity, salt-spray environments.
- Pulp & Paper / Mining: High-load, high-contamination environments requiring robust IP67 housing protection.
Engineering Advantages
- OEM Dimensional Accuracy: Machined to Bently Nevada factory tolerances — ensures drop-in replacement without re-calibration of the Proximitor® driver in most installations.
- 316L Stainless Steel Housing: Superior corrosion resistance versus standard 304 SS, critical for H₂S-rich or chloride-laden process environments.
- Integral Cable Design: Eliminates field-splice connection points, reducing signal noise and connector failure risk in high-vibration zones.
- Wide Thermal Range: Qualified to –35 °C / +177 °C, covering cryogenic LNG applications through high-temperature steam turbine bearing housings.
- API 670 Compliant: Meets the Machinery Protection Systems standard for radial vibration, axial position, and phase reference measurement.
System Architecture & Signal Flow
The 24701-33-05-00-024-04-02 operates as the field-sensing element within the Bently Nevada 3300 XL eddy-current transducer system:
- Probe Tip (this assembly) → generates an oscillating electromagnetic field at the shaft surface.
- Integral Coaxial Cable → transmits the high-frequency carrier signal to the Proximitor® driver with minimal impedance mismatch.
- 3300 XL Proximitor® Sensor → demodulates the carrier, outputs a DC voltage proportional to gap distance (–7.87 V/mm scale factor).
- 3500 Series Monitor Rack → digitizes, processes, and alarms on vibration amplitude, DC gap, and dynamic waveform data.
- DCS / SCADA Integration → 4–20 mA or digital outputs feed plant-wide condition monitoring and historian systems.
