Oiltech Controls Limited’s Insight: Long-Reach PrecisionThe Bently Nevada 330707-00-30-90-02-00 is a premium 11mm eddy current sensor for extreme displacement monitoring.Its 9.0-meter integrated cable length eliminates the need for extension cables in many local installations.The 11mm tip diameter provides a significantly larger linear range than standard 8mm probes, perfect for axial thrust measurement.Engineers at Oiltech Controls Limited recommend this model for large-scale hydro and steam turbines with massive shaft diameters.Featuring a ClickLoc coaxial connector, it ensures a secure, vibration-proof connection for critical safety interlocks.Configuration Breakdown (Suffix Logic Tree)330707 — 3300 XL 11 mm Probe (5/8-18 UNF thread, without armor)-00 — Unthreaded Length: 0.0 inches (Complete thread coverage for mounting flexibility).-30 — Overall Case Length: 3.0 inches.-90 — Total Length: 9.0 Meters (29.5 Feet) integrated FEP cable.-02 — Connector: Miniature coaxial ClickLoc connector (Standard cable type).-00 — Agency Approval: Not required (Standard Industrial non-Ex version).Technical Engineering SpecificationsProbe Tip Material: Polyphenylene sulfide (PPS) high-dielectric polymer.Case Material: AISI 304 Stainless Steel (SST) for superior corrosion resistance.Nominal DC Resistance: 8.5 Ω ± 1.1 Ω (Baseline for field health checks).Thermal Operating Range: -52°C to 177°C (-62°F to 351°F).Installation Torque: 15.2 N•m (Recommended) / 45.2 N•m (Maximum Limit).Pressure Sealing: Viton O-ring designed to seal differential pressure between tip and case.Thread Engagement: Maximum 0.938 inches depth for 5/8-18 threads.Cable Bend Radius: Minimum 25.4 mm (1.0 inch) to prevent triaxial shield damage.Diagnostic Capabilities & Typical ApplicationsAxial Position Monitoring: Essential for tracking rotor thrust position in heavy-duty compressors.Differential Expansion: Measuring the growth rate between turbine rotors and casings during start-up.High-Displacement Radial Vibration: Monitoring shaft orbits in large-clearance fluid-film bearings.Loop Integrity Diagnosis: The 8.5 Ω resistance spec allows for rapid verification of cable continuity without disassembly.Harsh Environment Protection: FEP insulation resists degradation from industrial oils, moisture, and common chemical solvents.Logistics & Warranty CommitmentWarranty Policy: 12-month industrial warranty provided by Oiltech Controls Limited.Condition: 100% New & Original in factory packing (Made in U.S.A.).Shipping Methods: Global priority delivery via FedEx, UPS, and DHL Express.Dispatch Time: Your 330707-00-30-90-02-00 will ship within 24-48 hours.Professional FAQ & Purchasing GuideWhy is a 9-meter probe used instead of a 1-meter probe with an 8-meter extension?A 9-meter integrated probe (-90) reduces signal loss at the junction and eliminates one potential failure point (the connector) inside the machine.What happens if the 11mm probe is installed too close to a metal shoulder?It will cause “side-view” interference, skewing the calibration. Ensure a minimum of 22mm clearance from surrounding metal for accurate readings.Is the 5/8-18 UNF thread interchangeable with metric mounts?No. If your machine uses M14 or M16 threads, you must order a different base model. Forced installation will damage the SST case.How do I know if my O-ring seal has failed?Check for oil migration inside the coaxial cable or at the Proximitor end. Note that seals may fail if exposed to temps below -34°C.Expert Selection Tip: System MatchingAlways match a 9m probe with a 9m Proximitor. Mixing a 9m probe with a 5m Proximitor will cause a severe scale factor error (deviation from 100 mV/mil).Contact Information Inquiries: [email protected] , 86 158 8020 0923Copyright © 2026 Oiltech Controls Limited.
