Bently Nevada 330103-10-12-05-11-05 3300 XL 8 mm Proximity Probe

Description

Option 10 (100 mm unthreaded length), Option 12 (120 mm case length), and Option 11 (ClickLoc connector with connector protector, FluidLoc cable) specify this 3300 XL 8 mm proximity probe configuration — 330103-10-12-05-11-05.

This metric-threaded transducer lacks outer protective armor, facilitating direct installation into threaded M10 x 1 ports. Operating with a 0.5-meter total cable length (Option 05) and carrying CSA, ATEX, and IECEx approvals (Option 05), it integrates directly with 3300 XL series Proximitor sensors. The integrated FluidLoc cable (Option 11) prevents process liquids or lubrication oils from migrating through the internal coaxial spaces, addressing sealing requirements in pressurized turbine housings.

Features

• Metric M10 x 1 Thread: Threaded case constructed from AISI 303 or 304 stainless steel without outer protective armor.
• 100 mm Unthreaded Length: Specified by Option 10, providing a 100 mm unthreaded portion of the 120 mm total case length.
• FluidLoc Cable (Option 11): Includes a specialized cable design that blocks lubricating oil and other process fluids from migrating through the internal coaxial cable structure.
• ClickLoc Connector with Protector: Equipped with a miniature gold coaxial ClickLoc connector and a pre-installed connector protector for mechanical and environmental defense.
• 0.5 Meter Total Length (Option 05): Total probe cable length of 0.5 meters (1.6 feet) optimized for standard system configurations.
• Hazardous Area Approvals (Option 05): Standard safety approvals covering CSA, ATEX, and IECEx installations.

Applications

• Machinery Lubrication Systems: Used in installations where the probe must pass through an environment flooded with pressurized turbine lube oil, where oil migration along standard cables could bypass seals.
• Radial Vibration and Axial Position: Used for shaft radial vibration, axial thrust position, and speed measurements on rotating machinery.
• Industrial Turbo-machinery: Installed in steam turbines, gas turbines, centrifugal compressors, reciprocating compressors, gearboxes, pumps, and generators.

Installation Guidelines

• Thread Engagement Limit: The maximum length of thread engagement for M10 x 1 threads is 15 mm. Avoid exceeding this to prevent binding.
• Gapping: Set the probe gap within the linear range (typically 1.0 mm or 50 mils offset, corresponding to approximately -9.0 VDC output).
• Bend Radius: Ensure the probe cable maintains a minimum bend radius of 25.4 mm (1.0 in) during installation to prevent signal attenuation or cable damage.
• Case Torque: Tighten the case to the recommended torque of 7.5 N-m (66 in-lbf). Do not exceed the absolute limit of 22.6 N-m (200 in-lbf) to avoid threading damage.
