Quick Detail

Description

The 330704-000-050-10-01-05 3300 XL 11 mm Proximity Probe is an advanced eddy current transducer designed for high-precision vibration, displacement, and position measurements in industrial automation systems. Featuring a large 11 mm probe tip, it offers an extended linear range compared to standard 8 mm probes, providing 3.94 V/mm (100 mV/mil) output for accurate non-contact measurements on fluid-film bearing machines. The probe incorporates a Miniature coaxial ClickLoc connector with connector protector, patented TipLoc and CableLoc designs with 330 N pull strength, and optional FluidLoc cables to prevent oil or liquid leakage. Constructed with 99.9% braided copper shielding and IP67-rated environmental resistance, it ensures signal integrity and reliable operation in dust, water, and humid industrial environments. Operating and storage temperature ranges of -40°C to +85°C support harsh industrial conditions. The probe is backward-compatible with 7200-series systems when fully replaced and provides secure, high-quality connections with gold-plated brass connectors, locknuts, and pre-drilled safety wire holes for enhanced operational safety. It is ideal for integration into PLCs, DCS, or condition monitoring systems in heavy-duty rotating machinery, turbines, compressors, and industrial process equipment.

Applications

Axial (Thrust) Position Measurements
Used on steam or gas turbines, the 11 mm probe monitors axial movement with high linearity and 3.94 V/mm output, allowing precise detection of thrust bearing wear or misalignment, optimizing maintenance schedules and avoiding catastrophic failures.

Differential Expansion Monitoring in Steam Turbines
Installed across turbine shafts, it measures ramp differential expansion during startup and shutdown, enabling predictive maintenance. Its extended linear range provides accurate measurements beyond standard 8 mm probes.

Rod Position or Rod Drop Monitoring on Reciprocating Compressors
Monitors piston and rod movement in reciprocating compressors with precise displacement signals. The probe’s patented CableLoc 330 N pull strength ensures secure attachment during vibration and high mechanical stress.

Tachometer and Zero-Speed Sensing
Outputs precise speed and zero-speed signals for rotating machinery. Its IP67 environmental rating ensures reliable signal integrity in oil-rich or dusty conditions, suitable for industrial automation and SCADA systems.

Phase Reference (Keyphasor) Signals for Condition Monitoring
Provides phase-locked Keyphasor signals for machinery monitoring and vibration analysis, enabling accurate synchronization of vibration data with rotational speed, supporting predictive maintenance and API 670 compliance.
