Description

The 31000-28-05-35-032-03-02 is an English Proximity Probe Housing Assembly designed to provide robust mechanical and environmental protection for proximity transducer systems. This specific configuration features a 3300 XL 8 mm probe with multiple approvals (Option 28), a 0.5 m probe cable (Option 05), and a 35 mm standoff adapter (Option 35). The assembly is constructed from high-strength polyphenylene sulfide (PPS), offering excellent corrosion resistance for industrial machinery environments. Proximity probe housing assemblies are essential for mounting probes through machine cases, facilitating radial vibration and Keyphasor measurements while allowing for external access to the probe and its extension cable. This design permits gap adjustment or probe replacement without requiring machine disassembly. This unit is fully compliant with API 670 standards for externally mounted proximity probe housings and is suitable for use in intrinsically safe hazardous area applications when installed with appropriate I.S. barriers and transducer systems.

Installation Guidelines

• Install the outer sleeve into the machine case first.
• Insert the probe sleeve into the assembly and adjust the probe gap according to the transducer system manual.
• Ensure the housing cover is tightened securely with captive screws after installation.
• If hole plugs are utilized, tighten the hole plug nuts to 0.5 N-m (5 in-lbs).
• For penetration lengths between 25 mm and 50 mm, counter boring the machine case may be necessary to reduce signal interference.
