Bently Nevada 330703-000-050-10-12-00 3300 XL 11 mm Proximity Probe

Description

330703-000-050-10-12-00 is a 3300 XL 11 mm proximity probe featuring an M14 x 1.5 thread, 0 mm unthreaded length (Option 000), and a 50 mm case length (Option 050). This probe is configured with a 1.0 meter total system length (Option 10) and uses a FluidLoc cable with a miniature coaxial ClickLoc connector (Option 12), ensuring secure connections in fluid-exposed environments. As part of the 3300 XL 11 mm Proximity Transducer System, this non-contact eddy-current probe is used for precise vibration and displacement measurements on fluid-film bearing machinery. The 3300 XL 11 mm system provides a 3.94 V/mm (100 mV/mil) output and is designed for applications requiring a longer linear range than standard 8 mm systems, such as axial (thrust) position, ramp differential expansion on steam turbines, and reciprocating compressor rod position measurements. This probe is an unarmored configuration (330703 series), suitable for installations where heavy mechanical abrasion protection is not required.

Features

• M14 x 1.5 thread: Standard metric mounting thread for 3300 XL 11 mm probe series.
• 0 mm unthreaded length: Precision unthreaded body configuration (Option 000).
• 50 mm case length: Standardized probe body length for specific installation depths (Option 050).
• 1.0 meter total length: Compatible system length for standard proximity monitoring chains (Option 10).
• FluidLoc cable: Specialized cable construction (Option 12) designed for environments where fluid sealing is critical.
• ClickLoc connector: Miniature coaxial connector system for robust, reliable signal transmission.
• Non-contact measurement: Enables wear-free monitoring of shaft vibration, position, and Keyphasor signals.

Applications

• Axial (thrust) position measurements
• Radial vibration and position monitoring for fluid-film bearing machines
• Ramp differential expansion measurements on steam turbines
• Rod position and rod drop measurements on reciprocating compressors
• Tachometer and zero speed measurements
• Phase reference (Keyphasor) signals

Installation Guidelines

• Ensure the total system length (probe + extension cable) matches the requirements of the Proximitor Sensor.
• Handle the ClickLoc connector with care to avoid damage to the center pin; ensure the connection is fully seated.
• Use appropriate torque values when installing M14 x 1.5 threaded probes to ensure proper mechanical seating.
• While the transducer system is robust, avoid electrostatic discharge (ESD) when handling the connector and Proximitor terminals.
• FluidLoc cables are specifically intended for oil-sealed environments; route cables to avoid high-temperature zones or sharp bends.
