Description
The Bently Nevada 31000-28-10-00-146-00-02 Proximity Probe Housing Assembly is a rugged vibration monitoring unit built for rotating machinery such as motors, pumps, compressors, and turbines. It integrates a 3300 XL 8 mm probe with multiple safety approvals, housed in a stainless steel enclosure designed to withstand harsh industrial conditions.

With a probe penetration depth of 14.6 inches and a 1.0 m (39 in) probe cable, this assembly enables accurate shaft vibration and displacement measurements even in deep or hard-to-reach installations. The 3/4-14 NPT mounting thread ensures secure installation, while the AISI 304 stainless steel sleeve with retaining chain offers excellent corrosion resistance.

Operating across a wide temperature range of -51 °C to +105 °C, the assembly is ideal for long-term use in environments with high temperature, high humidity, or strong mechanical stress.

It is part of Bently Nevada’s 31000/32000 proximity housing series, engineered to provide robust support, reliable environmental protection, and easy access for maintenance without dismantling the machine itself.
