Bently Nevada 31000-29-05-00-090-01-02 Proximity Probe Housing Assembly

Description

The 31000-29-05-00-090-01-02 is a specialized 31000-series proximity probe housing assembly configured with a 3300 XL 8 mm proximity probe and connector protector (Option 29). This assembly includes a 0.5 m probe cable (Option 05), a 90 mm probe penetration depth (Option 090), and one M25 conduit fitting (Option 01). The housing features a 3/4-14 NPT mounting thread (Option 02) and is designed to provide robust environmental and mechanical protection for transducer systems in industrial rotating machinery.

Used primarily for radially mounted transducers, this housing allows external access to the proximity probe and its extension cable. It permits essential maintenance, such as gap adjustment or probe replacement, without requiring disassembly of the machine case. Constructed from polyphenylene sulfide (PPS) thermoplastic with stainless steel components, the housing offers high corrosion resistance and complies with API 670 standards for externally mounted proximity probe housings.

Features

• Integrated 3300 XL 8 mm proximity probe with connector protector
• 0.5 m probe cable length for close-coupled monitoring applications
• 90 mm probe penetration depth for accurate target positioning
• Single M25 conduit fitting and two plugs
• 3/4-14 NPT mounting thread configuration
• PPS thermoplastic construction for corrosion resistance in harsh industrial environments
• Compatible with standard 3300 XL transducer systems for radial vibration and Keyphasor measurements

Applications

• Radial vibration monitoring for critical rotating machinery
• Keyphasor measurement and shaft position sensing
• Harsh environments requiring environmental and mechanical protection for transducers
• Applications where external access for probe maintenance is mandatory

Installation Guidelines

Ensure the outer sleeve is correctly installed into the machine case before inserting the probe sleeve. Adjust the probe gap according to the transducer system requirements. After connecting the probe cable, install the housing over the outer sleeve and secure it using the retainer and retaining nut. Tighten hole plugs to 0.5 N-m (5 in-lb) to maintain environmental sealing. Consult the 31000/32000 User Guide for complete grounding and shielding procedures.

Compliance and Certifications

Complies with API 670 standard for externally mounted proximity probe housings. Suitable for use in hazardous area applications when installed with approved transducer systems and appropriate intrinsically safe (I.S.) barriers.
