Bently Nevada 330703-000-040-10-01-05 3300 XL 11 mm Proximity Probe

Description

Option 000 (0 mm unthreaded length), Option 040 (40 mm case length), and Option 01 (coaxial ClickLoc connector with connector protector, standard cable) specify this metric 3300 XL 11 mm proximity probe configuration — 330703-000-040-10-01-05. This unarmored, non-contacting probe uses eddy-current technology to measure shaft vibration, axial position, and rotor displacement. It features metric M14 x 1.5 threading and has a total system length of 1.0 meter.

Compatible with the 3300 XL 11 mm Proximitor Sensor and extension cable, this model operates within an 11 mm transducer chain. The configuration includes a miniature coaxial ClickLoc connector with an integrated fluorosilicone connector protector. This provides a moisture-resistant seal for the probe-to-extension cable junction in industrial environments, without requiring external armor.

Features

• M14 x 1.5 metric thread option with a 40 mm overall case length and 0 mm unthreaded section.
• 1.0 meter (3.3 feet) integrated triaxial cable with standard FEP insulation.
• Miniature coaxial ClickLoc male connector with pre-installed fluorosilicone connector protector.
• Option 05 Multiple Approvals configuration certifying the device for ATEX, IECEx, and North American hazardous area classifications.
• Polyphenylene sulfide (PPS) probe tip and AISI 304 stainless steel case material construction.

Applications

Used in industrial environments for machinery protection on critical rotating equipment, including:

• Steam and gas turbine rotor position monitoring.
• Compressor shaft radial vibration measurement.
• Thrust bearing wear and axial displacement sensing.
• Hydroelectric generator shaft runout analysis.
• Keyphasor and speed measurement on industrial drivetrains.

Installation Guidelines

• Ensure proper thread engagement. For M14 x 1.5 threads, the maximum engagement length is 21 mm. Exceeding this may cause binding.
• Tighten standard metric cases to the recommended torque of 21.1 N-m (187 in-lb). Do not exceed the maximum rated limit of 63.3 N-m (560 in-lb).
• Maintain a minimum cable bend radius of 25.4 mm (1.0 inch) during routing to prevent core damage.
• Set the target probe gap using a digital voltmeter connected to the Proximitor Sensor test points, aiming for approximately 2.5 mm (100 mils) or -10 Vdc bias.
• Protect coaxial connectors from moisture and oil exposure; ensure the fluorosilicone connector protector is fully seated.
