Frequently Asked Questions (FAQ)

What probe is pre-installed in this housing?

This housing assembly (-27 option) comes with a Bently Nevada 3300 XL NSv series proximity probe already installed and ready for use.

What is the purpose of the standoff adapter?

The 1.5-inch standoff adapter spaces the housing away from the mounting surface. This ensures the probe tip is at the correct depth inside the machine for accurate measurement.

Can I use this housing with other probe models?

No. The 31000-27-05-15-040-03-02 is a complete, pre-configured unit for a specific 3300 XL NSv probe. It is not designed for field retrofitting with different probes.

What do the Type 4X and IP66 ratings mean for my application?

Type 4X means it is weatherproof, watertight, and corrosion-resistant. IP66 confirms it is totally dust-tight and can handle strong water jets. It is ideal for outdoor or washdown areas.

What cables does the included seal grip fit?

The cable seal grip includes three grommets. They fit cable outer diameters ranging from 1/8 inch (3.2mm) up to 3/8 inch (9.5mm). This covers most industrial sensor and conduit cables.
