330880-28-15-027-00-02 Bently Nevada PROXPAC XL Proximity Transducer

Product AbstractThe 330880-28-15-027-00-02 is an all-in-one PROXPAC XL Proximity Transducer system. It integrates a 3300 XL 8mm probe and a Proximitor sensor into a single, high-durability thermoplastic housing. This model features a 1.5-inch standoff and 27mm penetration, designed to simplify installation while providing precise vibration and position data for critical rotating machinery in hazardous areas.Oiltech Controls Limited’s InsightThe 330880-28-15-027-00-02 is a masterclass in field engineering. By housing the electronics at the measurement point, it eliminates failure points from long extension cables. The UV-resistant PPS housing is exceptionally durable in offshore environments where metal might corrode. Our data shows that the 3/4-14 NPT mounting provides a leak-proof interface, while the silicone isolation prevents false vibration signals caused by housing resonance.Configuration Breakdown & Suffix Tree�� 330880 — PROXPAC XL Proximity Transducer┗ �� -28 — Probe/Approval: 3300 XL 8mm Multiple Approvals┗ �� -15 — Standoff Adapter: 1.5 inch (B Dimension)┗ �� -027 — Penetration: 27 mm (C Dimension)┗ �� -00 — Fittings: No fittings (Plugs/Washers only)┗ �� -02 — Mounting Thread: 3/4-14 NPT (Required for Standoff)Core Technical SpecificationsModel: 330880-28-15-027-00-02Linear Range: 2.0 mm (80 mils)Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ±5%Housing Rating: IP66 Verified (BASEEFA)Operating Temp (Probe): -51 °C to 177 °CFrequency Response: 0 to 10 kHz ( 0, -3 dB)Input Power: -17.5 Vdc to -26 VdcMaterial: Glass-reinforced PPS ThermoplasticImpact Strength: Certified to 7 Joule (Ambient)Application & Machine CompatibilityReciprocating Compressors: Integrated rod drop and crankcase monitoring.Cooling Tower Fans: High-humidity resistance for exterior bearing mounts.Refinery Equipment: Multiple approvals for safe deployment in hazardous zones.Machine Diagnostics: Reliable orbital analysis and gap voltage tracking.Simplified Wiring: Reduces field installation time by eliminating separate Proximitor mounting.Logistics & WarrantyQuality Assurance: Includes a 12-Month Quality Guarantee.Priority Shipping: Worldwide delivery via FedEx, UPS, and DHL.Condition: Brand New & Original Bently Nevada Factory Packing.Professional FAQ & Selection GuideQuestion: What is the benefit of the PPS thermoplastic housing?Answer: It is immune to rust and highly resistant to UV and chemical corrosion, making it superior to aluminum in coastal or offshore plants.Question: How is total probe reach calculated for the 330880-28-15-027-00-02?Answer: Reach is the sum of the Standoff (1.5″) and Penetration (27mm). Ensure your port depth allows for the 1.27mm (50 mil) target gap.Question: Can I use field wiring longer than 300 meters?Answer: Max distance is 305 meters (1,000 ft). Longer runs cause high-frequency signal rolloff.Question: What if the gap voltage is more positive than -1 Vdc?Answer: This typically indicates an “over-gap” condition or the shaft target size is smaller than the 15.2mm minimum.Question: Why is the 3/4-14 NPT thread mandatory for this model?Answer: The -02 thread provides the structural strength required to support the standoff adapter and housing assembly safely.Contact Information Inquiries: [email protected] , 86 158 8020 0923Copyright © 2026 Oiltech Controls Limited.
