Bently Nevada 31000-28-05-15-030-02-02 English Proximity Probe Housing Assemblies

Description

The 31000-28-05-15-030-02-02 is a Bently Nevada 31000-series proximity probe housing assembly, configured for use with a 3300 XL 8 mm proximity probe and integrated connector protector (Option A: 28). This assembly is designed to provide robust mechanical and environmental protection for proximity transducers mounted through the machine case, ensuring reliable vibration and position monitoring in critical industrial machinery.

This configuration includes a 0.5 m (20 in) probe cable (Option B: 05) and is equipped for specialized mounting requirements with a 1.5-inch standoff adapter (Option C: 15) and a 3.0-inch (76 mm) probe penetration depth (Option D: 030). The housing assembly is constructed from high-strength polyphenylene sulfide (PPS) and stainless steel, meeting API 670 standards for externally mounted proximity probe housings. It features two M25 fittings with one plug (Option E: 02) and a 3/4-14 NPT mounting thread (Option F: 02), suitable for environments requiring direct threaded installation.

Installation Guidelines

• Install outer sleeve into the machine case before inserting the probe housing assembly.
• Adjust probe gap as required by the specific transducer system documentation.
• Connect probe cable and ensure the connector protector is secure.
• Tighten housing cover captive screws firmly after assembly.
• If using hole plugs, tighten hole plug nuts to 0.5 N-m (5 in-lbs).
• Ensure the machine casing is properly affixed to the bearing for radial vibration measurements to maintain signal accuracy.
