330704-000-060-90-02-CN Bently Nevada 3300 XL 11mm Probe | New 330704

Product OverviewThe 330704-000-060-90-02-CN is a cornerstone of the Bently Nevada 3300 XL 11 mm series, engineered for high-precision displacement and vibration monitoring.This metric-threaded transducer system offers an extended linear range compared to standard 8mm systems, making it ideal for large-scale turbomachinery.Engineering teams should download the official technical datasheet and wiring manual to ensure impedance matching across the 9.0-meter signal path.Configuration Breakdown & Logic Tree330704 — Base Model: 3300 XL 11 mm Probe (M14 x 1.5 thread)└── 000 — Unthreaded Length: 0 mm (Fully threaded case)└── 060 — Overall Case Length: 60.0 mm└── 90 — Total Length: 9.0 meters (29.5 feet)└── 02 — Miniature coaxial ClickLoc connector with standard cable└── CN — Agency Approval: Country Specific (China/Regional)Technical SpecificationsBrand: Bently NevadaModel: 330704-000-060-90-02-CNMeasurement Range: 4.0 mm (160 mils) for wide-gap applications.Sensitivity: 3.94 V/mm (100 mV/mil) ±10% at room temperature.Frequency Response: DC to 10 kHz; compatible with high-speed rotation.Temperature Range: -52°C to 177°C; maintains seal integrity above -34°C.Resistance: 8.5 ± 1.1 ohms (Center to outer conductor).Magnetic Interference: 0.001 to 0.027 mil pp/gauss (60 Hz up to 300 Gauss).Material: PPS tip with AISI 304 Stainless Steel probe body.Oiltech Controls Limited’s InsightThe 330704-000-060-90-02-CN provides a critical advantage in “hot” industrial environments where thermal expansion of the rotor is significant.Our field experience shows that the 11mm tip prevents “bottoming out” of the signal in machines with large axial floats.We recommend this specific 3300 XL configuration for retrofitting older DCS systems that require robust metric mounting without structural modifications.Suitability & Diagnostic CapabilityCompatible Equipment: Large Steam Turbines, Hydro-generators, Centrifugal Compressors, and Boiler Feed Pumps.Diagnostic Power: Enables real-time tracking of Shaft centerline position, Orbit analysis, and Sub-synchronous vibration detection.Logistics & ProcurementCondition: Brand New & Original in Factory Sealed Packing.Warranty: Guaranteed 12-month factory coverage.Dispatch: Ships within 24-48 hours via FedEx, UPS, or DHL for global priority.Professional FAQ & Selection GuideQuestion: How do I choose between a 5-meter and a 9-meter total length?Answer: Selection depends entirely on the Proximitor Sensor calibration. A 9-meter probe like the 330704 must be used with a 9-meter Proximitor to avoid linear error. Question: Can I install this probe in a mounting hole with 1/2-20 threads?Answer: No, the 330704 uses an M14 x 1.5 metric thread. For English threads, a different base model number is required. Question: What is the risk of over-tightening the probe case?Answer: Exceeding 63.3 N·m can deform the stainless steel case or damage the internal triaxial cable junction. Question: Why is the “CN” approval suffix important for my project?Answer: The CN suffix ensures compliance with specific regional safety and hazardous area certifications.Question: How does the PPS tip handle chemical exposure in turbines?Answer: PPS is highly resistant to synthetic lubricants, though physical impact during rotor rub remains the primary risk.Contact Information Inquiries: [email protected], 86 158 8020 0923Copyright © 2026 Oiltech Controls Limited.
