Description

The 31000-28-10-00-010-01-02 is a fully assembled English proximity probe housing configured with a 3300 XL 8 mm transducer system (Option 28: multiple approvals). This assembly includes a 1.0 m probe cable (Option 10), 1.0 inch probe penetration (Option 010), and is mounted using a 3/4-14 NPT thread (Option 02). The housing is equipped with one M25 conduit fitting and two plugs (Option 01). Designed for heavy-duty industrial environments, these housing assemblies provide robust mechanical and environmental protection for proximity probes and extension cables. The system enables external access to the transducer, facilitating probe gap adjustment or replacement without requiring machine disassembly. Constructed from polyphenylene sulfide (PPS) and corrosion-resistant stainless steel, the 31000 series is fully compliant with API 670 standards for externally mounted proximity probe housings, ensuring compatibility with standard radial vibration and Keyphasor measurement installations.

Features

• Includes integrated 3300 XL 8 mm proximity probe with multiple hazardous area approvals
• PPS thermoplastic housing body offers high strength and chemical resistance
• API 670 compliant design for reliable machine case mounting
• External access allows for probe gap adjustment and replacement while machinery is operating
• 3/4-14 NPT mounting thread for standard industrial interfaces
• Configured with one M25 conduit fitting and two hole plugs for flexible cable routing
• 1.0 inch (25.4 mm) probe penetration depth

Applications

• Radially mounted transducers for machine case vibration monitoring
• Keyphasor measurement and speed sensing
• Critical rotating machinery protection in power generation, petrochemical, and oil and gas industries
• Hazardous area environments (when installed with appropriate I.S. barriers)

Installation Guidelines

Install the outer sleeve directly into the machine case before inserting the probe sleeve to ensure proper alignment. Adjust the probe gap according to the requirements of the 3300 XL monitoring system. When using hole plugs, ensure they are tightened to 0.5 N-m (5 in-lbs) to maintain environmental sealing. For probe penetration lengths between 25 mm and 50 mm, consider counter-boring the machine case to minimize potential side-view effects.
