Bently Nevada 330703-000-050-10-11-05 3300 XL 11 mm Proximity Probe

Description

330703-000-050-10-11-05: 3300 XL 11 mm proximity probe with an M14 x 1.5 metric thread, Option 000 unthreaded case length (0 mm), Option 050 overall case length (50 mm), Option 10 total length (1.0 m), Option 11 FluidLoc cable with connector protector, and Option 05 multiple approvals.

Unlike configurations utilizing standard cabling or bare connectors (such as Option 02), this variant includes a FluidLoc cable (Option 11) to block oil and other process fluids from leaking through the cable interior. Additionally, the pre-installed connector protector provides environmental sealing in wet or humid atmospheres. This metric-threaded, non-armored probe integrates into the 3300 XL 11 mm transducer system alongside the 330780 Proximitor Sensor and 330730 extension cable for shaft vibration and axial position measurement on rotating machinery.

Features

• Metric thread design: M14 x 1.5 thread without armor (base model 330703).
• FluidLoc cable (Option 11): Blocks oil and other liquids from leaking from the machinery housing through the inner cable sheath.
• Connector protection: ClickLoc miniature coaxial connector equipped with a fluorosilicone connector protector.
• 0 mm unthreaded length (Option 000) combined with a 50 mm overall case length (Option 050).
• 1.0 meter total system lead length (Option 10) for direct proximity transmitter connections.
• Multiple Agency Approvals (Option 05) supporting hazardous area installations (ATEX, IECEx, and CSA).

Applications

Typical application scenarios for this transducer include:

• Steam turbine ramp differential expansion monitoring.
• Fluid-film bearing industrial machinery shaft vibration tracking.
• Reciprocating compressor piston rod drop and rod position measurements.
• Turbine rotor axial thrust position monitoring.
• Industrial rotating machinery speed and phase reference (Keyphasor) applications.

Installation Guidelines

Ensure correct mechanical installation and alignment using the following procedures:

• Maintain a minimum cable bend radius of 25.4 mm (1.0 in) during routing.
• Set the probe gap to the recommended nominal distance of 2.5 mm (100 mils) using a feeler gauge or by monitoring the Proximitor Sensor voltage.
• Secure the probe in position using the pre-drilled safety wire holes on the locknut.
• Torque the M14 x 1.5 thread case to the recommended installation torque of 21.1 N m (187 in lb). Do not exceed the maximum rating of 63.3 N m (560 in lb).
• Ensure the ClickLoc connection is fully mated (finger-tight up to 0.565 N m) and protected by the pre-installed fluorosilicone connector protector.

Compliance and Certifications

This configuration meets the following standards when used as part of a compatible 3300 XL transducer system:

• ATEX / IECEx: Intrinsically safe (Ex ia IIC T5...T1 Ga), non-sparking/increased safety (Ex nA/ec IIC T4/T5 Gc).
• CSA: Approved for Class I, Division 1 and Division 2 hazardous area environments.
• CE Directives: Electromagnetic Compatibility (EMC) Directive 2014/30/EU, RoHS Directive 2011/65/EU.
