Description

The 31000-28-10-00-114-03-02 is an English Proximity Probe Housing Assembly designed to provide mechanical and environmental protection for proximity probes mounted through machine casings. This configuration includes a 3300 XL 8 mm proximity probe (Option 28: multiple approvals), a 1.0 m probe cable (Option 10), and a probe penetration depth of 114 mm (Option 114). The assembly is constructed from polyphenylene sulfide (PPS) and corrosion-resistant stainless steel, complying with API 670 standards for externally mounted probe housings. This assembly (Option 00 for standoff adapter, Option 03 for fittings, Option 02 for 3/4-14 NPT thread) allows for external access to the proximity probe and its extension cable. This design facilitates efficient gap adjustment or probe replacement without requiring the disassembly of the machine case, which is critical for maintaining uptime in rotating machinery applications.

Features

• Integrated 3300 XL 8 mm proximity probe with multiple hazardous area approvals
• Polyphenylene sulfide (PPS) housing material for high strength and corrosion resistance
• Designed for radial vibration and Keyphasor measurements
• External probe access allows for gap adjustment and replacement without machine disassembly
• Includes cable seal grip and fittings for armored probe cable management
• Compliant with API 670 standard for externally mounted proximity probe housings
• 3/4-14 NPT mounting thread

Applications

• Centrifugal pumps and compressors
• Steam and gas turbines
• Electric motors and generators
• Fans and blowers
• Rotary machinery monitoring in hazardous locations
• Radial vibration and shaft position measurement chains

Installation Guidelines

• Ensure the machine casing is affixed to the bearing to obtain an accurate relative vibration signal.
• Install the outer sleeve into the machine case before fitting the housing.
• Slide the retainer under the retaining nut and tighten the nut securely.
• Ensure the housing cover is tightened with captive screws after final gap adjustment.
• Tighten all hole plug nuts to 0.5 N-m (5 in-lbs) if unused ports are plugged.
