Bently Nevada 24701-16-10-00-090-03-02 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 303 stainless steel housing block directly into the machine frame casing utilizing the designated 3/4-14 NPT connection threads (Standoff adapter is bypassed in this setup).
• Verify that the internal 304 stainless steel probe sleeve extends precisely 9.0 inches into the housing port to establish correct geometric alignment over the rotating shaft target.
• 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 option 03 cable seal grip to form a tight compression seal around your instrument wiring, apply the thread seal, and torque the dome cover down securely.

Technical FAQs

Q1: What structural components are integrated inside the 24701 series assembly to shield field equipment?
A1: The complete 1.8 kg setup consists of a heavy-duty dome cover that threads directly into the main housing body, dedicated ports for rigid conduit piping connections, a customized length probe tracking sleeve, specialized synthetic O-rings, a reverse-mount proximity transducer probe, and integrated thread seals. This design maintains atmospheric integrity around the sensor core under high 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 1.8 kg body, and provides stable tracking across deep 9.0-inch internal reaches.

Q3: How do the various grommets included with the 03 fittings option assist in system deployment?
A3: The multi-grommet cable seal kit supports reliable field adaptation by providing tight, pressure-resistant sealing matrices for three distinct outer-diameter ranges: 1/8 to 3/16 inches, 1/4 to 5/16 inches, and 5/16 to 3/8 inches. This allows plant teams to run diverse brands of armored or unarmored coaxial instrument wires without compromising the housing's environmental protection rating.
