Bently Nevada 31000-16-10-00-085-03-02 Proximity Probe Housing Assembly

Description

The 31000-16-10-00-085-03-02 is a Bently Nevada 31000 Proximity Probe Housing Assembly configuration featuring a pre-installed 3300 XL 8 mm proximity probe (Option 16) and a 1.0 m probe cable (Option 10). This assembly is designed to provide mechanical and environmental protection for proximity transducers when mounted through the machine case, ensuring accurate vibration and position measurements in industrial environments.

Constructed from polyphenylene sulfide (PPS), a high-strength thermoplastic with excellent corrosion resistance, the 31000 series housing allows for external access to the probe and extension cable. This design facilitates gap adjustment or probe replacement without requiring the disassembly of the machine case. This specific model includes a 3/4-14 NPT mounting thread (Option 02) and is compliant with API 670 standards for externally mounted proximity probe housings.

Features

• Pre-configured 3300 XL 8 mm proximity probe for immediate integration into monitoring chains
• High-strength polyphenylene sulfide (PPS) housing construction provides superior corrosion resistance
• Designed for external access to facilitate probe gap adjustment and replacement without machine disassembly
• Compatible with standard conduit fittings (3/4-14 NPT) for robust cable protection
• Compliant with API 670 Standard for externally mounted proximity probe housings
• Mechanical and environmental protection for radial vibration and axial position transducers

Applications

• Radially mounted proximity probes for shaft vibration monitoring
• Keyphasor and axial position measurements
• Heavy-duty rotating machinery protection in oil and gas, petrochemical, and power generation sectors
• Hazardous area applications when installed with appropriate I.S. barriers and transducer systems

Installation Guidelines

Ensure the machine casing is affixed to the bearing when measuring radial vibration to maintain signal accuracy. Install the outer sleeve into the machine case, insert the probe sleeve, and adjust the probe gap as required. Secure the housing by sliding the retainer under the retaining nut and tightening. Ensure conduit fittings are properly sealed if hardline conduit is utilized. For penetration lengths greater than 12 in (305 mm), additional sleeve support near the probe is required to prevent resonance.

Compliance and Certifications

The 31000/32000 housing assembly is compliant with the American Petroleum Institute (API) 670 Standard. When installed with an approved transducer system and appropriate I.S. barriers, this assembly is suitable for use in intrinsically safe hazardous area applications. This unit is not an explosion-proof housing.
