Bently Nevada 31000-16-05-00-023-02-02 31000 Proximity Probe Housing Assembly

Description

The 31000-16-05-00-023-02-02 is a Bently Nevada 31000 Proximity Probe Housing Assembly configured with a 3300 XL 8 mm proximity probe (Option 16) and a 0.5 m probe cable (Option 05). This housing assembly provides essential mechanical and environmental protection for proximity probes mounted through the machine case, facilitating external access for gap adjustments or probe replacement without the need to disassemble the machinery.

This unit features a probe penetration length defined by Option 023 and is supplied without a standoff adapter (Option 00). The assembly includes two M25 conduit fittings with one plug (Option 02) and uses a 3/4-14 NPT mounting thread (Option 02). Constructed from high-strength polyphenylene sulfide (PPS) and corrosion-resistant stainless steel, this housing is fully compliant with API 670 standards for externally mounted proximity probe housings. It is suitable for diverse industrial environments, including radial vibration and Keyphasor measurements on rotating machinery.

Installation Guidelines

Install the outer sleeve into the machine case according to the site-specific clearance requirements. Insert the probe sleeve and adjust the probe gap before securing the housing over the outer sleeve. Ensure the retainer is correctly positioned under the retaining nut and tighten securely. If hole plugs are used, tighten them to 0.5 N-m (5 in-lbs) to maintain environmental sealing. All conduit and cable glands must be tightened to ensure proper mechanical and environmental protection ratings are maintained.
