Bently Nevada 31000-16-10-15-201-02-02 English Proximity Probe Housing Assemblies

Description

The 31000-16-10-15-201-02-02 is an English proximity probe housing assembly configured with a 3300 XL 8 mm proximity probe (Option 16), 1.0 m probe cable length (Option 10), 1.5 inch standoff adapter length (Option 15), 20.1 inch probe penetration depth (Option 201), two 3/4-14 NPT fittings with one plug (Option 02), and 3/4-14 NPT mounting threads (Option 02). This assembly is part of the Bently Nevada 31000 series, specifically engineered to provide robust mechanical and environmental protection for proximity probes mounted through machinery cases.

Used primarily for radial vibration and Keyphasor measurements, this housing assembly allows for external access to the probe and its extension cable. This design facilitates efficient gap adjustment and probe replacement without requiring the disassembly of the machine case. Constructed from polyphenylene sulfide (PPS) and corrosion-resistant stainless steel, the 31000 series adheres to API 670 standards for externally mounted proximity probe housings and is suitable for use in hazardous area applications when installed with appropriate I.S. barriers and transducer systems.

Features

• Probe Configuration: Includes factory-installed 3300 XL 8 mm proximity probe for high-accuracy vibration and position monitoring.
• Housing Material: High-strength, corrosion-resistant polyphenylene sulfide (PPS) body with stainless steel components.
• External Access: Simplifies maintenance by allowing probe gap adjustment and replacement from outside the machine case.
• API 670 Compliance: Fully compliant with American Petroleum Institute standards for externally mounted probe housings.
• Fittings: Equipped with two 3/4-14 NPT conduit fittings and one plug for secure, flexible cable routing.
• Mounting: 3/4-14 NPT mounting thread option for standard machinery case interface.

Applications

• Radial vibration monitoring for rotating machinery
• Keyphasor and speed measurements
• Axial position measurement (when used in approved configurations)
• Hazardous area applications (when paired with appropriate I.S. barriers)
• Oil and gas, petrochemical, and power generation machinery protection

Installation Guidelines

Ensure the outer sleeve is correctly installed into the machine case before fitting the housing assembly. When adjusting the probe gap, verify the probe tip remains clear of the target material. Use the provided conduit fittings and plugs to seal unused ports to maintain the integrity of the enclosure. For sleeve lengths exceeding 305 mm (12 in), it is recommended to use a probe support or oil seal to prevent resonance. Always verify that all retainer nuts and housing cover screws are tightened to the specified torque after final calibration.
