Turbomachinery Vibration Monitoring Solution – Bently Nevada 31000-16-05-00-063-03-02 | 3300 Series
Where This Product Is Used
The Bently Nevada 31000-16-05-00-063-03-02 Proximity Probe Housing Assembly is engineered for continuous, non-contact vibration and position measurement in rotating machinery. Typical deployment environments include:
- Steam & Gas Turbines – shaft radial vibration monitoring at bearing journals
- Centrifugal Compressors – rotor dynamic displacement measurement in petrochemical and LNG plants
- Pumps & Fans – axial thrust and radial position sensing in power generation facilities
- Gearboxes – gear mesh frequency and shaft orbit analysis
- Marine Propulsion Systems – continuous shaft monitoring in offshore and naval applications
This housing assembly is a critical mechanical interface component that positions and protects the eddy-current probe tip at the precise gap distance required for accurate signal output, typically 1.0 mm (40 mil) nominal gap.

Application-Specific FAQ
Q: Is this probe compatible with the Bently Nevada 3500 monitoring system?
A: Yes. The 31000/32000 series probes are fully compatible with the 3500 rack system when paired with the correct Proximitor® driver module. Verify the driver part number matches the probe tip diameter (8 mm for this model).
Q: What is the nominal gap voltage for this probe?
A: The standard operating gap is 1.0 mm (40 mil), corresponding to approximately –10 VDC output from the Proximitor® sensor. Refer to Bently Nevada calibration sheet 141536-01 for the full gap-vs-voltage curve.
Q: Can this housing be used in a Zone 1 ATEX environment?
A: The standard part number is not ATEX-rated. For hazardous area installations, specify the Ex-rated variant or contact us for the appropriate suffix configuration.
Q: Do you provide calibration certificates?
A: We supply OEM calibration data sheets where available. Third-party NIST-traceable calibration can be arranged upon request at additional cost.
Q: What is the difference between the 31000 and 32000 series?
A: The 31000 series uses a standard armored cable jacket; the 32000 series features an extended-temperature, high-flex cable for applications with tight bend radii or elevated ambient temperatures above 150 °C.
