Bently Nevada 330703-000-060-10-11-05 3300 XL 11 mm Proximity Probe

Description

Option 000 (0 mm unthreaded length), Option 060 (60 mm case length), and Option 11 (ClickLoc connector with protector, FluidLoc cable) define this metric 3300 XL 11 mm proximity probe configuration — 330703-000-060-10-11-05. Featuring an unarmored M14 x 1.5 threaded case, this eddy-current proximity probe belongs to the Bently Nevada 3300 XL 11 mm transducer system, serving as an essential non-contact sensor for industrial machinery vibration and displacement monitoring. Its 1.0-meter total length and specialized FluidLoc cable option prevent lubricating oil or other process fluids from leaking out of the machine housing along the cable's interior.

This specific configuration contrasts with standard options by utilizing a FluidLoc cable (Option 11) instead of standard coaxial cable, ensuring robust oil sealing at high pressures. The addition of a factory-installed connector protector provides environmental shielding for the miniature ClickLoc connection. Certified with Multiple Approvals (Option 05), the probe is ready for installation in hazardous industrial environments. The probe operates seamlessly with the 3300 XL 11 mm Proximitor Sensor and compatible extension cables, delivering a linear range of 4.0 mm (160 mils) and a nominal scale factor of 3.94 V/mm (100 mV/mil) for reliable rotating machinery diagnostics.

Features

• Thread configuration: Metric M14 x 1.5 threaded case (unarmored) with 60 mm total case length (Option 060) and fully threaded design (0 mm unthreaded, Option 000).
• Leak prevention: FluidLoc cable (Option 11) prevents oil or gas leakage through the internal structure of the cable.
• Environmental protection: Miniature coaxial ClickLoc connector with pre-installed connector protector (Option 11) for environmental shielding.
• System length: 1.0-meter total system length (Option 10) designed to interface with 3300 XL 11 mm extension cables and Proximitor sensors.
• Hazardous certifications: Multiple Approvals (Option 05) including ATEX, IECEx, and North American hazardous area certifications.
• Measurement specifications: Linear measurement range of 4.0 mm (160 mils) with an incremental scale factor of 3.94 V/mm (100 mV/mil).

Applications

• Turbine and compressor shaft radial vibration and axial position measurement.
• Thrust bearing wear and rotor position tracking in petrochemical processing equipment.
• Critical rotating machinery protection on machinery utilizing M14 x 1.5 threaded mount ports.
• Aggressive oil or gas environments where cable leakage path prevention is required.

Installation Guidelines

Ensure the probe is gapped correctly to the target shaft (recommended nominal gap of 2.5 mm / 100 mils). Respect the maximum case torque limit of 63.3 N-m (560 in-lb) for M14x1.5 metric cases; the recommended installation torque is 21.1 N-m (187 in-lb) to avoid casing deformation. Always maintain a minimum bend radius of 25.4 mm (1.0 in) for the FluidLoc triaxial cable to prevent internal conductor damage. Connectors must be kept clean, dry, and securely tightened finger-tight; the pre-installed connector protector provides supplemental moisture and environmental shielding.

Compliance and Certifications

Option 05 (Multiple Approvals) designates certification under major international safety standards for explosive atmospheres:

• ATEX/IECEx: Intrinsically Safe (Ex ia IIC Ga, Ex ia IIIC Dc) and Non-sparking/Increased Safety (Ex nA IIC Gc, Ex ec IIC Gc) when installed per Bently Nevada guidelines.
• North America (cNRTLus): Class I, Zone 0, AEx/Ex ia IIC T4/T5 Ga; Class I, Division 2, Groups A, B, C, D; Class II; Class III.
• Functional Safety: SIL 2 certified under systematic capability (HFT=0), or SIL 3 in redundant architectures (HFT=1).
• RoHS: Compliant with European Community Directive 2011/65/EU and China RoHS regulations.
