Overview
The Bently Nevada 31000-00-00-00-120-00-02 is a premium proximity probe housing assembly engineered for non-contact shaft displacement and vibration monitoring on rotating machinery. The 31000 Series is an industrial-grade shaft vibration and displacement monitoring system designed specifically for monitoring the health of rotating machinery, capable of simultaneously measuring shaft vibration and axial displacement with high-precision, high-reliability monitoring data. This Type 4X housing variant supports 12-inch probe penetration, making it suitable for machines with thicker casings where standard housings fall short.
Key Features
- Type 4X rating from Canadian Standards Association (CSA) and IP66 rating verified by SC115582-1 (e) 106, ensuring robust protection against dust and high-pressure water jets
- 12 inch accurate positioning penetration with 3/4-14 NPT mounting thread for proper mounting
- Operates reliably from -51°C to +105°C (-60°F to +221°F) across industrial temperature extremes
- CENELEC EN50014 rating for electrostatic dissipation in hazardous areas
- Probe not required (option 00), allowing flexibility to order compatible 31000 series probes separately based on application requirements

- Made in U.S.A.
Typical Applications
31000/32000 Proximity Probe Housing Assemblies are recommended when mounting proximity probes through the machine case and are typically used for radially mounted transducers, whether vibration or Keyphasor measurements. Common installations include:
- Rotating machinery vibration monitoring (turbines, compressors, pumps)
- Outdoor washdown environments, marine applications, and dusty industrial areas requiring IP66 protection
- Hazardous-area installations requiring CENELEC compliance
- Machines with wall thickness up to 11 inches requiring extended probe reach
