Compact Offset Housing for Tight Machine Spaces
Install sensors where space is limited. This Bently Nevada 31000 housing features a 1.5-inch standoff and 2.6-inch penetration. It provides flexible mounting for your 3300 XL 8mm probe. Achieve precise measurements in compact industrial environments with full protection.
Key Benefits for Space-Constrained Installations
- Optimized Compact Design: Combines a moderate 1.5-inch standoff with 2.6-inch probe reach. Ideal for installations with physical obstructions near the mounting point.
- Essential Fittings Package: Includes Fittings Option 06: one NPT fitting, one reducer, and two plugs. Provides core components for a sealed connection without extra clutter.
- Short Cable for Neat Routing: Equipped with a 0.5-meter (20-inch) integrated cable. Minimizes excess cable in control panels for a clean, professional installation.
- Robust Industrial Protection: Maintains full NEMA 4X/IP66 ratings. The conductive PPS housing is safe for use in hazardous locations and withstands impacts.
- Wide Operational Range: Reliable performance across a broad temperature spectrum from -51°C to +105°C.

Simple Installation Process
Start by threading the 1.5-inch standoff adapter into your mounting point. Then attach the housing assembly. Always use a calibrated tool to apply 260 in-lb of torque to the retaining nut. This ensures a proper seal and mechanical security.
Recommended Applications
- Electric motor bearing monitoring in crowded mechanical rooms.
- Fan and blower vibration measurement on tight skids.
- Installing probes on equipment with limited radial clearance.
- General-purpose machinery protection where a short offset is beneficial.
Installation Support & Common Questions
What is the main use for a 1.5-inch standoff adapter?
The 1.5-inch standoff creates a small offset. It provides clearance for the housing body from the mounting surface. This is useful when there are pipes, brackets, or uneven surfaces nearby.
Does “Fittings Option: 06” include cable seals?
No, Option 06 includes pipe plugs and a reducer fitting for port sealing. It does not include cable seal grips. For cable sealing, you would need to source a separate cable gland compatible with the housing’s entry thread and your cable diameter.
Is the 0.5m cable suitable for most installations?
The 20-inch cable is ideal for short runs to a local junction box. For longer distances, plan to use an approved extension cable from the junction box to the monitoring system.
What support do you offer after purchase?
All products are covered by a 12-month quality warranty. For technical questions, our engineering team provides support. We ensure fast delivery via FedEx, UPS, or DHL to keep your projects on schedule.
What is a best practice when installing with a standoff?
Apply a small amount of thread sealant on the standoff adapter’s male threads. Do this before mounting it to the equipment. This prevents process media from leaking through the threads, which the O-ring alone may not seal.
