Quick Detail

Description

The 330709-050-120-10-02-00 3300 XL 11 mm Proximity Probe delivers a 3.94 V/mm (100 mV/mil) output for precise non-contact vibration and displacement measurements on fluid-film bearing machines. The 11 mm probe tip extends the linear range compared to the standard 3300 XL 8 mm probe, supporting axial (thrust) position, ramp differential expansion on steam turbines, rod position on reciprocating compressors, tachometer readings, and Keyphasor phase signals. The 330709-050-120-10-02-00 3300 XL 11 mm Proximity Probe features a 1.0 meter total length, M14 x 1.5 threaded case, 50 mm unthreaded section, and 120 mm overall case length. Its miniature coaxial ClickLoc connector, standard cable, and 99.9% braided copper shielding provide secure signal transmission. The 330709-050-120-10-02-00 3300 XL 11 mm Proximity Probe operates in -40°C to +85°C environments and is IP67 rated for dust and water resistance. ClickLoc connectors, patented TipLoc molding, and CableLoc design ensure robust probe-to-cable attachment. Optional FluidLoc cables and connector protectors allow safe operation in oil-contaminated or humid environments, while pre-drilled locknut holes support secure mounting.

Applications

Axial (Thrust) Position Measurement on Turbines
The 330709-050-120-10-02-00 3300 XL 11 mm Proximity Probe provides precise axial shaft position measurement on turbines using its 11 mm tip and 3.94 V/mm sensitivity. Its extended 50 mm unthreaded length ensures consistent monitoring over larger displacements, reducing the need for frequent calibration.

Ramp Differential Expansion Monitoring on Steam Turbines
Using the 330709-050-120-10-02-00 3300 XL 11 mm Proximity Probe, differential shaft expansion across turbine ramps can be detected with high accuracy. The probe’s 120 mm overall case length and 1.0 meter cable allow flexible placement in confined turbine housings, capturing small positional changes effectively.

Rod Position and Rod Drop Measurement on Reciprocating Compressors
The 330709-050-120-10-02-00 3300 XL 11 mm Proximity Probe tracks compressor rod movement, leveraging the 11 mm probe tip and 99.9% braided copper shielding for low-noise signal transmission. Real-time rod drop detection is supported by IP67 environmental protection, ensuring reliable operation in lubricated compressor environments.

Tachometer and Zero Speed Measurement
By providing high-resolution phase reference signals, the 330709-050-120-10-02-00 3300 XL 11 mm Proximity Probe enables precise zero-speed detection and tachometer measurements. The miniature coaxial ClickLoc connector ensures secure signal transmission over the 1.0-meter cable without signal degradation.

Phase Reference (Keyphasor) Signal Generation
The 330709-050-120-10-02-00 3300 XL 11 mm Proximity Probe delivers stable Keyphasor signals to monitoring systems. Its TipLoc molded probe tip combined with CableLoc cable attachment provides 330 N pull strength, ensuring the probe tip remains firmly bonded under vibration and thermal cycles.

Specifications

Competitive Advantage

Extended Linear Range for Large Displacement Monitoring
The 11 mm tip of the 330709-050-120-10-02-00 3300 XL 11 mm Proximity Probe provides a longer linear measurement range compared to standard 8 mm probes, enabling accurate measurement of larger axial and radial movements without requiring multiple sensors.

Robust Mechanical and Electrical Connections
The 330709-050-120-10-02-00 3300 XL 11 mm Proximity Probe uses gold-plated ClickLoc connectors and TipLoc molded tips for secure, low-resistance connections. Combined with CableLoc attachment, the probe can withstand 330 N pull strength, reducing maintenance due to loose connectors.

Enhanced Environmental Protection for Harsh Conditions
With IP67-rated housing and optional FluidLoc cable, the 330709-050-120-10-02-00 3300 XL 11 mm Proximity Probe prevents water and oil ingress, maintaining signal integrity in wet, humid, or lubricated industrial environments.

Flexible Installation and Upgrade Options
The 330709-050-120-10-02-00 3300 XL 11 mm Proximity Probe supports multiple probe threads (M14 x 1.5 standard) and locknuts with pre-drilled safety wire holes, allowing secure installation in new or retrofit systems. Its full compatibility with 7200-series upgrades ensures smooth system transitions.

Reliable High-Resolution Output
The 330709-050-120-10-02-00 3300 XL 11 mm Proximity Probe provides a 3.94 V/mm output, enabling precise vibration and displacement measurements. The combination of 99.9% braided copper shielding and RJ45 connectors reduces electrical noise, ensuring accurate monitoring in demanding industrial applications.
