Quick Detail

Description

The 3300 XL 11 mm Proximity Probe (330703-000-100-10-11-05) is a high-precision industrial automation sensor designed for non-contacting vibration and displacement measurements on fluid film bearing machinery. Featuring an 11 mm probe tip, it provides an extended linear measurement range, outperforming standard 8 mm transducers for applications that require precise axial or radial shaft monitoring. With an overall case length of 100 mm and total cable length of 1.0 meter, the probe integrates a Miniature Coaxial ClickLoc connector with 99.9% braided copper shielding to ensure signal integrity and reliability in industrial environments.

The probe housing is IP67 rated for dust and water resistance, with operational temperatures from -40°C to +85°C, making it suitable for demanding industrial and automation systems. The M14 x 1.5 threaded case allows secure mounting with up to 21 mm of thread engagement, while the TipLoc and CableLoc designs ensure robust mechanical connection, 330 N (75 lb) pull strength, and protection against fluid ingress. Applications include axial thrust measurements, rod drop detection, phase reference (Keyphasor) signal generation, tachometer readings, and ramp differential expansion on turbines.

This probe is designed to replace the 7200-series 11 mm and 14 mm systems, providing enhanced reliability, compatibility with 3300 XL monitoring systems, and a long-lasting solution for automation and condition monitoring applications. Optional FluidLoc cables and connector protectors provide enhanced environmental protection in oil-contaminated or humid environments.

Applications

1. Axial (Thrust) Position Monitoring
Measures axial shaft displacement on turbines or compressors, preventing mechanical interference and optimizing performance. The long 11 mm tip allows measurement over a 2 mm linear range, accommodating shaft movement.

2. Steam Turbine Differential Expansion Monitoring
Monitors ramp differential expansion in turbines to detect thermal growth or misalignment, enhancing efficiency and avoiding unplanned downtime.

3. Rod Position and Rod Drop Measurement
Provides accurate position sensing for reciprocating compressors and pumps, supporting predictive maintenance and reducing mechanical wear.

4. Tachometer and Zero-Speed Detection
Generates phase reference and zero-speed signals for rotating machinery control, ensuring precise timing and speed measurement in automation systems.

5. Phase Reference (Keyphasor) Signals
Delivers accurate Keyphasor signals for vibration monitoring systems, enabling synchronized data acquisition and real-time machine condition analysis.

Specifications

Competitive Advantage

1. Extended Linear Range
The 11 mm probe tip increases the measurement linear range compared to standard 8 mm probes, improving accuracy for large-shaft applications.

2. High-Strength Cable and Tip Design
Patented TipLoc and CableLoc designs provide up to 330 N pull strength, preventing disconnection and ensuring long-term reliability in industrial environments.

3. Environmental Protection
IP67 rating, optional connector protectors, and FluidLoc cables resist dust, water, and oil ingress, making it suitable for harsh factory conditions.

4. Universal Compatibility
Replaces 7200-series 11 mm and 14 mm probes and integrates with 3300 XL monitoring systems, simplifying upgrades and system standardization.

5. Robust Electrical Performance
Gold-plated ClickLoc connectors and 99.9% copper shielding minimize signal interference, providing high-fidelity vibration and displacement measurements.
