Bently Nevada 31000-16-10-15-030-03-02 English Proximity Probe Housing Assembly

Description

The 31000-16-10-15-030-03-02 is an English proximity probe housing assembly designed for robust machinery vibration and position monitoring. This configuration includes a 3300 XL 8 mm proximity probe (Option A: 16) with a 1.0 m cable (Option B: 10), integrated with a standoff adapter and probe penetration assembly for precise gap adjustment and external maintenance access. The housing is constructed from polyphenylene sulfide (PPS), a high-strength thermoplastic offering superior corrosion resistance, complemented by stainless steel components for long-term durability. This housing assembly serves as a protective enclosure for proximity probes, allowing for installation through the machine case for radial vibration or Keyphasor measurements. The design facilitates external probe access, enabling gap adjustments or replacement without requiring internal machine disassembly. It is fully compliant with the American Petroleum Institute (API) 670 standard for externally mounted proximity probe housings and is suitable for use in intrinsically safe hazardous area applications when paired with appropriate transducer systems and I.S. barriers.

Features

• Equipped with a 3300 XL 8 mm Proximity Probe for reliable eddy-current displacement measurement
• Constructed from polyphenylene sulfide (PPS) and corrosion-resistant stainless steel for harsh industrial environments
• Permits external probe gap adjustment and replacement, reducing maintenance downtime
• Features 3/4-14 NPT mounting thread for secure installation into machine casings
• Includes fittings (Option EE: 03) and mounting thread (Option FF: 02) configurations for flexible connection and routing
• API 670 compliant design ensures standardized mechanical and environmental protection

Applications

• Radial vibration monitoring for rotating machinery (turbines, compressors, pumps, motors)
• Keyphasor measurement for phase reference and speed monitoring
• External mounting in oil and gas, petrochemical, and power generation facilities
• Hazardous area applications (when used with approved I.S. barriers)

Installation Guidelines

• Install the outer sleeve into the machine case before mounting the housing assembly.
• Ensure the probe sleeve is properly positioned to allow for probe gap adjustment.
• Disconnect the probe cable before fitting the housing over the outer sleeve.
• Tighten the retaining nut securely after sliding the retainer in place.
• If hole plugs are used, tighten the hole plug nuts to 0.5 N-m (5 in-lbs) to maintain environmental protection.
• For applications with high vibration or moisture, ensure all conduit fittings are correctly sealed.
