Bently Nevada 31000-00-00-00-059-03-02 English Proximity Probe Housing Assembly

Description

The 31000-00-00-00-059-03-02 is an English Proximity Probe Housing Assembly designed for mechanical and environmental protection of proximity transducers mounted through machine cases. This specific configuration features a 59 mm probe penetration depth (Option 059) and is provided without an integrated probe or cable (Options 00/00/00). It includes two plugs, one M20 fitting, and one cable seal grip with grommets for armored probe cables (Option 03) and utilizes a 3/4-14 NPT mounting thread (Option 02). This housing assembly allows external access to proximity probes and extension cables, facilitating gap adjustments or probe replacements without the need for machine disassembly. Constructed from polyphenylene sulfide (PPS), a high-strength thermoplastic with excellent corrosion resistance, and stainless steel, it is compliant with API 670 standards for externally mounted proximity probe housings. It is intended for use in radially mounted transducer applications and provides environmental sealing when installed correctly.

Features

• Configuration: 31000 series English Proximity Probe Housing Assembly
• Probe Penetration (Option 059): 59 mm depth
• Fittings (Option 03): Two plugs, one M20 fitting, and one cable seal grip with grommets for armored probe cable

Installation Guidelines

• Install the outer sleeve into the machine case before mounting the housing.
• Adjust the probe gap according to the specific 3300 XL proximity probe user manual.
• Ensure all hole plugs and conduit fittings are tightened securely to maintain the environmental seal (0.5 N-m / 5 in-lbs for plugs).
• The housing is not explosion-proof; use approved housing (e.g., CA21000 or CA24701) for explosion-proof requirements.
• When measuring radial vibration, ensure the machine casing is securely affixed to the bearing.
