Bently Nevada 330880-28-15-035-00-02 PROXPAC XL Proximity Transducer

Description

Option 28 (3300 XL 8 mm probe with Multiple Approvals) and Option 15 (1.5 in standoff adapter) specify this PROXPAC XL Proximity Transducer configuration — 330880-28-15-035-00-02.

This integrated proximity transducer assembly combines the probe and Proximitor sensor into a single polyphenylene sulfide (PPS) housing. The self-contained design eliminates the need for an external extension cable between the probe and Proximitor sensor, as well as the need for a separate Proximitor junction enclosure. Field wiring connects directly between the monitors and the internal terminals. This configuration features a 3.5 in probe penetration depth (Option 035), no conduit fittings (Option 00), and a 3/4-14 NPT mounting thread (Option 02) suitable for severe industrial machinery case interfaces.

Features

• Transducer probe with multiple hazardous area approvals (ATEX, IECEx, and CSA) for explosion-proof and intrinsically safe installations.
• Integrated Proximitor sensor in the housing lid to eliminate external extension cables.
• Conductive glass-fiber-reinforced polyphenylene sulfide (PPS) thermoplastic housing rated IP66 and Type 4X.
• 1.5 in (38 mm) standoff adapter with a 3/4-14 NPT thread for rigid casing mounting.
• 3.5 in (89 mm) stainless steel probe sleeve length for direct case penetration.
• Supplied with two plugs and two washers under the no-fittings option.

Applications

• Shaft vibration and axial position measurements on rotating machinery.
• Direct integration on turbines, compressors, pumps, and industrial gearboxes.
• Environments requiring IP66 or Type 4X protection against chemical exposure, moisture, and dust.
• Hazardous industrial environments requiring intrinsically safe or non-incendive field wiring.

Installation Guidelines

• Torque the housing retaining nut to 29.5 N-m (260 in-lb).
• Torque the probe sleeve locknut to 39.3 N-m (350 in-lb) to maintain the environmental pressure seal.
• Verify that the internal grounding liner and retaining plate are clean and securely fastened.
• Ensure field wiring terminals are protected by an enclosure of at least IP54.
• Maintain a minimum separation of 40 mm (1.6 in) for axial installations or 38 mm (1.5 in) for radial configurations to avoid cross-talk.
