Bently Nevada 330701-00-25-10-11-05 3300 XL 11 mm Proximity Probe

Description

Option 00 (0.0 in unthreaded length), Option 25 (2.5 in overall case length), Option 10 (1.0 m total length), Option 11 (ClickLoc connector with protector, FluidLoc cable), and Option 05 (Multiple approvals) specify the exact configuration of this 330701-00-25-10-11-05 3300 XL 11 mm Proximity Probe. This non-contacting eddy-current sensor operates within a 3300 XL 11 mm Proximity Transducer System to provide dynamic displacement and static position measurements on rotating machinery. The unarmored 1/2-20 UNF threaded case configuration allows direct installation in tapped machine housings where external mechanical armor is unnecessary, while the integrated FluidLoc cable prevents moisture and process oil from migrating through the internal probe cable.

Unlike configuration variants that feature standard coaxial cables (Option 01 or 02) or lack mechanical protection at the connection point, this probe utilizes Option 11 to provide both a FluidLoc barrier and a factory-installed connector protector, protecting the ClickLoc coaxial connection from contamination. Additionally, with Option 05, this probe is certified for multiple hazardous area environments (including ATEX, IECEx, and CSA), whereas standard Option 00 probes have no agency approvals. It features an 11 mm tip diameter that provides an extended 4.0 mm (160 mils) linear range, which is significantly longer than standard 8 mm systems, making it suitable for large axial thrust measurements, ramp differential expansion, and reciprocating compressor rod drop monitoring.

Features

• Option 00 Unthreaded Case: Features a 0.0-inch unthreaded length, making the 2.5-inch case (Option 25) fully threaded with 1/2-20 UNF threads for flexible mounting depth.
• Option 11 FluidLoc Cable: Incorporates an FEP-insulated FluidLoc triaxial cable that prevents oil and moisture leakage through the interior of the probe cable, combined with a pre-installed coaxial connector protector.
• Option 10 Total Length: Designed as a 1.0-meter (3.3 feet) integral probe system, typically paired with a 4.0-meter extension cable to complete a 5.0-meter system length.
• Option 05 Multiple Approvals: Fully certified under ATEX, IECEx, and CSA standards for safe operation in Class I Division 1/2 and Zone 0/2 hazardous locations.
• 11 mm Tip Diameter: Provides an extended linear range of 4.0 mm (160 mils) and a nominal scale factor of 3.94 V/mm (100 mV/mil).

Applications

• Axial thrust position measurements on steam and gas turbines
• Ramp differential expansion measurements on industrial turbomachinery
• Rod drop and rod position monitoring on reciprocating compressors

Installation Guidelines

• Hand-tighten the probe case into the tapped hole and then tighten to the recommended installation torque of 15.2 N-m (133 in-lb). Do not exceed the maximum rated case torque of 45.2 N-m (400 in-lb).
• Maintain a minimum cable bend radius of 25.4 mm (1.0 in) when routing the integral FluidLoc triaxial cable to avoid signal attenuation or conductor damage.
• Ensure that the total probe length (1.0 m) and extension cable length (typically 4.0 m) match the 5.0-meter system length designated on the 3300 XL Proximitor Sensor.
• Ensure the ClickLoc connection is fully protected with the pre-installed connector protector to prevent ingress of industrial oils, water, or other process contaminants.
