Quick Detail

Description

The 330710-000-050-02-00 3300 XL 11 mm Proximity Probe is a high-precision non-contacting transducer designed for industrial automation applications requiring extended linear range and robust reliability. Featuring an 11 mm probe tip, this sensor delivers a 3.94 V/mm (100 mV/mil) output, enabling accurate vibration and displacement measurements on fluid film bearing machines. Its M14 x 1.5 threaded probe case supports a maximum thread engagement of 21 mm, while the unthreaded length is 0 mm and the overall case length is 50 mm. The 3300 XL 11 mm Proximity Probe comes with a 1.0-meter (3.3 feet) standard cable terminated with miniature coaxial ClickLoc connectors, providing secure, gold-plated connections with up to 330 N pull strength. With 99.9% braided copper shielding and IP67-rated dust and water resistance, this transducer system withstands harsh industrial environments, operating reliably from -40°C to +85°C. Its patented TipLoc and CableLoc designs ensure durability and stability in automation systems, making it ideal for upgrades from legacy 7200-series 11 mm and 14 mm systems while maintaining compatibility with 3500 Monitoring System configurations.

Applications

Axial (Thrust) Position Measurements
The 3300 XL 11 mm Proximity Probe accurately measures axial positions in turbine and compressor thrust bearings, providing real-time displacement data for automation monitoring with a linear range up to 11 mm, ensuring precise control of critical rotating equipment.

Ramp Differential Expansion Measurements on Steam Turbines
Designed for high-precision turbine monitoring, this probe detects differential shaft expansion across multiple stages with sub-micron resolution, supporting predictive maintenance and optimizing automation system efficiency.

Rod Position or Rod Drop Measurements on Reciprocating Compressors
The probe enables precise tracking of rod displacement, allowing automated systems to detect rod drop events instantly. Its 3.94 V/mm output ensures minimal signal deviation even under extreme temperatures from -40°C to +85°C.

Tachometer and Zero Speed Measurements
By generating high-fidelity phase signals, the 3300 XL 11 mm transducer provides accurate speed feedback for automation controllers, supporting zero-speed detection and rotational speed monitoring in industrial compressors and turbines.

Phase Reference (Keyphasor) Signals
The probe delivers reliable Keyphasor signals for vibration phase analysis, facilitating automated fault detection, condition monitoring, and integration with 3500 monitoring systems for enhanced operational safety and efficiency.

Specifications

Competitive Advantage

Extended Linear Range
The 11 mm probe tip allows longer linear displacement measurement compared to standard 8 mm systems, enabling precise detection of large shaft excursions in automation applications.

Rugged Environmental Resistance
IP67-rated construction, combined with 99.9% braided copper shielding, ensures the probe functions reliably in dust, moisture, and temperature extremes (-40°C to +85°C), reducing maintenance downtime.

High-Strength Secure Connections
Gold-plated ClickLoc connectors and patented CableLoc design provide up to 330 N pull strength, preventing accidental disconnection in automated systems and harsh industrial environments.

Upgrade-Friendly Compatibility
Designed to replace legacy 7200-series 11 mm and 14 mm transducers, the 3300 XL 11 mm supports seamless upgrades in 3500 Monitoring Systems while maintaining automation system integrity.

Durable Mechanical Design
TipLoc molded probe tips and threaded M14 x 1.5 probe cases with maximum 21 mm engagement ensure mechanical stability under high vibration conditions, extending sensor life and improving reliability in critical automation operations.
