Bently Nevada 21000-28-10-00-180-00-02 Probe Housing 18in

Product Overview

The Bently Nevada 21000-28-10-00-180-00-02 is an aluminum Proximity Probe Housing Assembly engineered for hazardous and harsh industrial environments. Designed to house a 3300 XL 8 mm eddy current proximity probe, this assembly allows safe, externally accessible probe installation, adjustment, and replacement without requiring the disassembly of the machine housing or main bearing caps.

This specific configuration features a 3300 XL 8 mm probe with multiple hazardous area approvals, a 1.0 m (39 in) probe cable, an 18.0-inch penetration sleeve length, and a standard 3/4-14 NPT mounting thread connection. Constructed without a standoff adapter or additional fittings, the entire assembly has a net weight of approximately 1.1 kg (2.4 lbs), providing a compact, lightweight solution for continuous vibration and shaft position monitoring.

Core Technical Advantages

• External Probe Adjustability: Allows field technicians to set or replace proximity transducers without shutting down machinery or opening main housing covers.
• Hazardous Area Certified: Equipped with a 3300 XL 8 mm proximity probe featuring global approvals (ATEX/IECEx/CSA/FM) for explosive gas and dust environments.
• Extended Sleeve Penetration: Features an 18.0-inch sleeve length designed for deep-reach application requirements across industrial turbines, compressors, and gearboxes.
• Rugged Aluminum Enclosure: Precision-machined aluminum body rated for IP66 / NEMA 4X protection against ingress of moisture, oil, and atmospheric contaminants.

Technical Specifications

Installation & Gap Calibration Guide

• Mounting Preparation: Thread the 3/4-14 NPT mounting body into the machine casing port using appropriate NPT thread sealant to maintain IP66 environmental sealing.
• Penetration & Gap Setting: Insert the 18.0-inch probe sleeve into the housing, adjusting the probe position using a multimeter or Bently Nevada TK-3 calibration unit to set the proper voltage gap (typically -9.0 V DC for 3300 XL transducers).
• Cable Connection: Route the 1.0 m probe cable to the extension cable and Proximitor Sensor, taking care not to exceed the minimum bending radius of the coaxial cable.
