Bently Nevada 31000-16-05-00-035-02-02 English Proximity Probe Housing Assemblies

Description

The 31000-16-05-00-035-02-02 is an English Proximity Probe Housing Assembly designed for the 31000 series, featuring a 3300 XL 8 mm proximity probe (Option 16) and a 0.5 m (20 in) probe cable (Option 05). This configuration specifies a 35 mm probe penetration depth (Option 035) without a standoff adapter (Option 00), utilizing two M25 fittings (Option 02) and a 3/4-14 NPT mounting thread (Option 02).

These assemblies provide mechanical and environmental protection for proximity transducers when mounted through a machine case. They allow for external access to the transducer and extension cable, which simplifies gap adjustment or probe replacement without requiring machine disassembly. Constructed from polyphenylene sulfide (PPS), this assembly offers high-strength thermoplastic properties and excellent corrosion resistance. It is compatible with 3300 XL eddy-current transducer systems and adheres to the API 670 standard for externally mounted proximity probe housings.

Installation Guidelines

Ensure the machine casing is securely affixed to the bearing when measuring radial vibration to maintain accurate relative vibration signals. When installing, thread the housing onto the 3/4-14 NPT connection, adjust the probe gap through the housing, and secure with the provided retaining nut. If unused holes are present, utilize the provided hole plugs and tighten to 0.5 N-m (5 in-lbs) to maintain environmental protection ratings.

Compliance and Certifications

The 31000 series housing is compliant with American Petroleum Institute (API) 670 Standard. When installed with appropriate I.S. barriers and approved transducer systems, this assembly is suitable for use in hazardous area applications.
