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

Description

330103-05-10-10-12-05 specifies a 3300 XL 8 mm proximity probe configured with M10 x 1 metric thread, 50 mm unthreaded length, 100 mm overall case length, a 1.0-meter total length, and a FluidLoc cable with miniature ClickLoc connector and CSA/ATEX/IECEx hazardous area approvals. This configuration does not include a stainless steel protective armor jacket on the cable.

Unlike standard coaxial cables, the FluidLoc cable option (Option 12) features specialized construction to prevent oil, process liquids, or gases from leaking through the inner core of the cable if the primary probe seal fails. This specific configuration is suited for installations where the transducer must pass through pressurized or oil-filled barriers without introducing leakage paths. The unarmored design facilitates flexible routing within tight conduits or dry spaces. The probe operates as an eddy-current sensor, translating physical distance to a target into a proportional electrical signal when paired with a matching 3300 XL Proximitor sensor and extension cable.

Features

• M10 x 1 metric thread case configuration without protective stainless steel armor.
• FluidLoc cable construction blocks oil or process liquids from leaking along the cable interior.
• Miniature ClickLoc coaxial connector provides a positive, tactile lock connection.
• Option 05 delivers CSA, ATEX, and IECEx hazardous area certifications.
• 50 mm unthreaded length allows deep insertion or specific recessed mounting clearances.
• 100 mm overall case length provides mechanical stability in deep-well or standard mounting brackets.

Applications

• Shaft radial vibration monitoring on critical rotating machinery such as turbines, compressors, and pumps.
• Axial rotor position and thrust measurements in oil-lubricated machine housings.
• Industrial processes requiring liquid-tight or gas-tight sealing barriers along signal cabling.
• Hazardous area environments requiring certified intrinsically safe or non-incendive instrumentation.

Installation Guidelines

Ensure that the mounting bracket supports the M10 x 1 threaded body securely. Maintain an unthreaded probe length that avoids mechanical interference with the target material while providing proper support. The probe case thread has a maximum torque limit of 7.5 N-m (66 in-lbf). Verify that the minimum bend radius of 25.4 mm (1.0 in) is not breached when routing the FluidLoc cable. Do not overtighten coaxial connectors; finger-tighten the gold ClickLoc connectors until they lock into position.

Compliance and Certifications

The 330103-05-10-10-12-05 is certified under agency approval Option 05, including:

• CSA: Intrinsically Safe and Non-Incendive certifications for Class I, Division 1 and Division 2 hazardous locations.
• ATEX: Zone 0, Zone 1, and Zone 2 protection classes for explosive atmospheres.
• IECEx: International certification for hazardous locations with gas and dust group categories.
