Description

The 31000-16-05-00-059-02-02 is a 31000 series proximity probe housing assembly, configured with a 3300 XL 8 mm proximity probe (Option A: 16) and a 0.5 meter probe cable (Option B: 05). This housing assembly is used for mounting proximity probes through a machine case to provide radial vibration or Keyphasor measurements. The assembly provides mechanical and environmental protection for the transducer, allowing for external access to the probe and cable for maintenance, gap adjustment, or replacement without requiring machine disassembly. This unit is constructed from polyphenylene sulfide (PPS), a high-strength thermoplastic offering excellent corrosion resistance, complemented by stainless steel components. The assembly includes two M25 fittings and one plug (Option E: 02) and features a 3/4-14 NPT mounting thread (Option F: 02). It is designed to comply with API 670 standards for externally mounted proximity probe housings and is suitable for use in hazardous area applications when installed with appropriate I.S. barriers and transducer systems.

Features

• Probe: 3300 XL 8 mm proximity probe installed
• Cable Length: 0.5 meter (20 in)
• Standoff Adapter: None (Option C: 00)
• Probe Penetration: 59 mm (Option D: 059)
• Fittings: Two M25 fittings, one plug (Option E: 02)
• Mounting Thread: 3/4-14 NPT (Option F: 02)
• Material: Polyphenylene sulfide (PPS) housing with stainless steel components
• Compliance: API 670 standard for externally mounted proximity probe housings

Applications

• Radial vibration monitoring on rotating machinery
• Keyphasor measurements for speed and phase reference
• Hazardous area applications (when used with approved transducer systems and I.S. barriers)
• Environments requiring external access for probe maintenance and gap adjustments

Installation Guidelines

• Ensure the machine casing is affixed to the bearing for accurate relative vibration signals.
• Install the outer sleeve into the machine case before fitting the housing.
• Adjust the probe gap by inserting the probe sleeve to the required depth.
• Tighten all hole plug nuts to 0.5 N-m (5 in-lbs) if unused holes are present.
• Ensure conduit fittings are correctly tightened to maintain environmental protection ratings.
