Bently Nevada 32000-28-05-05-110-03-02 Metric Proximity Probe Housing Assemblies

Description

32000-28-05-05-110-03-02: Bently Nevada metric proximity probe housing assembly featuring an integrated 3300 XL 8 mm proximity probe with multiple hazard approvals (Option 28), a 0.5 m probe cable length (Option 05), a 50 mm standoff adapter length (Option 05), a 110 mm probe penetration depth (Option 110), M20 fittings with a cable seal grip for armored probe cables (Option 03), and a 3/4-14 NPT mounting thread (Option 02).

This housing allows external access to the proximity probe and its extension cable, permitting convenient gap adjustment or probe replacement without dismantling the machinery casing. Constructed from high-strength, glass-reinforced polyphenylene sulfide (PPS) thermoplastic with conductive fibers, the assembly provides high physical durability and chemical resistance. Other components, such as the outer sleeve and exterior screws, are constructed of corrosion-resistant AISI 303 and AISI 304 stainless steel. It complies with the American Petroleum Institute (API) 670 Standard for externally mounted proximity probe housings, offering Type 4X and IP66 environmental protection.

Features

• Option 28 specifies an integrated Bently Nevada 3300 XL 8 mm proximity probe with multiple hazardous area approvals (CSA, ATEX, IECEx).
• Option 05 provides a 0.5 m (20 in) probe cable length.
• Option 05 designates a 50 mm standoff adapter length.
• Option 110 specifies a 110 mm probe penetration sleeve length.
• Option 03 provides two plugs, one M20 conduit fitting, and one cable seal grip with grommets for armored probe cable.
• Option 02 provides a 3/4-14 NPT mounting thread (required with the standoff adapter option).
• External access design allows fast gap adjustment and probe replacement without machinery disassembly.
• Glass-reinforced polyphenylene sulfide (PPS) housing body offers high impact strength and corrosion resistance.
• Stainless steel (AISI 303 and AISI 304) construction for sleeves, retainers, chains, and exterior screws.
• Dual O-ring sealing system utilizes a Viton O-ring inside the probe case and a Neoprene O-ring between the sleeve and housing.

Applications

• Radial vibration monitoring on critical rotating machinery.
• Keyphasor (phase reference) and shaft speed measurements.
• API 670 compliant installation on steam turbines, gas turbines, compressors, pumps, and gearboxes.
• Hazardous area industrial environments requiring intrinsically safe transducer installations.

Installation Guidelines

• Install the outer sleeve into the machine case. Ensure proper thread engagement.
• Insert the probe sleeve and adjust the probe gap relative to the target surface.
• Disconnect the probe cable temporarily to fit the housing over the outer sleeve.
• Slide the retainer under the retaining nut, and tighten the retaining nut to the recommended torque of 29.4 N-m (260 in-lb).
• Re-connect the probe cable and ensure the cable connector protector is secure.
• Install the housing cover and tighten captive screws.
• If using conduit hole plugs, torque the plug nuts to 0.5 N-m (5 in-lb) to maintain the environmental seal.
