Bently Nevada 24701-28-10-00-110-03-02 Proximity Probe Housing Assembly

The assembly functions as a heavy-duty, environmental shielding enclosure designed to house and protect a reverse-mount proximity probe in harsh industrial process conditions. By utilizing a ruggedized, explosion-proof layout, this mechanical module enables precise shaft vibration and axial position measurements on turbines, compressors, and large rotating machinery while sealing internal electrical links from ambient moisture and hazardous gas leakage.

Technical Specifications

Quick Installation Guide

• Mount the main 1.1 kg anodized aluminum housing block directly into the machinery frame casing utilizing the designated 3/4-14 NPT interface connection threads.
• Verify that the internal probe sleeve extends precisely 11.0 inches past the mounting plane into the casing to establish correct geometric alignment over the rotating target shaft.
• Carefully thread the reverse-mount 3300 XL 8mm probe through the internal guide tube, feeding its 1.0-meter trailing coaxial wire smoothly into the main junction dome area.
• Select the appropriate rubber wire grommet size (supporting 1/8 to 3/16, 1/4 to 5/16, or 5/16 to 3/8 inches) inside the cable seal grip to create an airtight lock around the miniature male coaxial connector run, then screw the outer dome cover down tightly.

Technical FAQs

Q1: What structural components are integrated inside the 24701 series assembly to shield field equipment?
A1: The complete 1.1 kg setup consists of a specialized dome cover that threads directly into the anodized aluminum body shell, integrated ports for conduit wiring networks, an elongated 11.0-inch probe tracking sleeve, robust sealing O-rings, a reverse-mount proximity transducer probe, and active thread seals. This design maintains atmospheric integrity around the sensor core under extreme pressures.

Q2: Why is a direct-mount configuration preferred over standoff adapter options for deep reach installations?
A2: This specific model features the 00 standoff and 02 mounting options, which allow the assembly to lock tightly flush onto the machine faceplate via 3/4-14 NPT connections. Direct-mounting lowers the external mass profile, decreases leverage vibration vectors across the 1.1 kg body, and provides stable tracking across deep 11.0-inch internal reaches.

Q3: How does the housing maintain sealing performance when subjected to harsh, pressurized chemical environments?
A3: Constructed out of high-grade anodized aluminum, the 24701 housing is rated for a maximum internal pressure of 1500 psi while supporting a wide thermal operating profile from -40°C up to +100°C. Coupled with the 03 fittings package (which features a 3/4-14 to 1/2-14 NPT reducer and a multi-grommet cable seal grip), it safely isolates the internal miniature male coaxial connections from moisture or corrosive vapors.
