Bently Nevada 21000-16-10-00-297-03-02 – Proximity Probe Housing Assembly | 3300 XL Series Platform
Engineering Background
The Bently Nevada 3300 XL Series represents the industry benchmark for continuous machinery protection in rotating equipment applications. Developed by Baker Hughes (Bently Nevada), this platform has been deployed globally across power generation, oil & gas, petrochemical, and heavy industrial facilities where unplanned downtime carries catastrophic operational and financial consequences.
Product Positioning
The 21000-16-10-00-297-03-02 is a precision-engineered proximity probe housing assembly designed to mechanically protect and accurately position eddy-current proximity probes in high-vibration, high-temperature machinery environments. It provides the structural interface between the probe tip and the monitored shaft, ensuring consistent gap distance, signal integrity, and long-term measurement reliability. This component is a direct OEM-equivalent replacement for installed 3300 XL system infrastructure.

Proven Application Environments
- Power Generation: Steam turbines, gas turbines, hydro generators — radial and axial vibration monitoring
- Oil & Gas: Compressor trains, centrifugal pumps, expanders — continuous shaft displacement measurement
- Petrochemical / Refining: Critical rotating machinery per API 670 machinery protection requirements
- Marine & Offshore: Propulsion shafting and auxiliary machinery in harsh salt-air environments
- Pulp & Paper / Steel: High-speed rolls, fans, and blowers requiring non-contact vibration sensing
- Nuclear / Utility: Safety-critical turbine-generator sets with continuous online monitoring
Engineering Advantages
- OEM-Equivalent Fit: Direct mechanical replacement for existing 3300 XL installations — no re-engineering or adapter required
- Signal Integrity Preservation: Precision-machined bore maintains probe-to-shaft gap tolerance within ±0.025 mm
- Corrosion Resistance: 316 SS construction withstands process fluids, steam, and aggressive atmospheres
- Vibration Immunity: Rigid housing design eliminates probe resonance artifacts in high-frequency measurement environments
- Sealed Construction: IP67 rating prevents moisture ingress that would degrade eddy-current field linearity
- Long Service Life: Designed for continuous 24/7 operation in API 670-compliant machinery protection systems
System Architecture & Signal Flow
The 21000-16-10-00-297-03-02 housing assembly integrates into the complete Bently Nevada 3300 XL transducer chain as follows:
- Probe Tip (housed within this assembly) → generates eddy-current field directed at rotating shaft target
- Extension Cable → transmits raw oscillator signal from probe to proximitor
- Proximitor / Oscillator-Demodulator (3300 XL) → converts gap distance to DC voltage output (typically −18 VDC nominal)
- 3500 / 3300 Monitor Rack → processes voltage signal for alarm, trip, and trending functions
- DCS / SCADA Integration → 4–20 mA or digital output to plant control system
Correct housing installation is critical: probe gap must be set to OEM-specified linear range (typically 1.0–2.0 mm) using a calibrated gap tool before commissioning.
