Bently Nevada 31000-28-10-00-133-03-02 English Proximity Probe Housing Assembly

Description

The 31000-28-10-00-133-03-02 is an English Proximity Probe Housing Assembly designed for 3300 XL 8 mm proximity probe integration. This specific configuration features an 8 mm probe with an integrated connector protector (Option 28), a 1.0 m probe cable (Option 10), and a probe penetration depth of 133 mm (Option 133). It is configured without a standoff adapter (Option 00) and utilizes 3/4-14 NPT mounting threads (Option 02).

The 31000 series housing is constructed from polyphenylene sulfide (PPS), a high-strength thermoplastic offering superior corrosion resistance for harsh industrial environments. This housing provides essential mechanical and environmental protection for transducer systems, allowing for external access to the probe and extension cable. This design facilitates efficient gap adjustment and probe replacement without requiring the disassembly of the machinery casing, adhering to API 670 standards for externally mounted proximity probe housings.

Features

• Option 28: Includes 3300 XL 8 mm proximity probe with connector protector.
• Option 10: 1.0 m (39 in) probe cable length.
• Option 00: Standoff adapter not required.
• Option 133: 133 mm (approx. 5.2 in) probe penetration depth.
• Option 03: Fittings include two plugs, one M20 fitting, and one cable seal grip with grommets for armored cable.
• Option 02: 3/4-14 NPT mounting thread.
• Material: Polyphenylene sulfide (PPS) housing with stainless steel components for corrosion resistance.
• Protection: Provides mechanical and environmental sealing per API 670 requirements.

Applications

Used primarily for radially mounted transducers in heavy industrial rotating machinery. This assembly is suitable for vibration and Keyphasor measurements in:

• Power generation plants (gas and steam turbines)
• Oil and gas upstream and downstream processing
• Petrochemical and chemical manufacturing
• Water treatment and mining facilities

Installation Guidelines

Install the outer sleeve into the machine case before inserting the probe sleeve to adjust the probe gap. The housing fits over the outer sleeve; slide the retainer under the retaining nut and tighten securely. When using cable glands or hole plugs, ensure they are tightened to 0.5 N-m (5 in-lbs) to maintain environmental integrity. Ensure the machine casing is properly affixed to the bearing when measuring radial vibration to maintain signal accuracy.

Compliance and Certifications

This assembly is fully compliant with the American Petroleum Institute (API) 670 Standard for externally mounted proximity probe housings. When installed with an approved transducer system and appropriate barriers, this housing supports use in hazardous area applications.
