Quick Detail

Description

The 330703-000-040-10-12-00 3300 XL 11 mm Proximity Probe is an industrial-grade proximity transducer engineered for high-accuracy non-contact vibration and displacement measurements in advanced automation and rotating machinery systems. As part of the 3300 XL proximity transducer platform, the 3300 XL 11 mm probe features a large tip diameter that extends the linear range and enhances signal fidelity under dynamic load conditions. Using a 3.94 V/mm output, the 3300 XL 11 mm Proximity Probe is optimized for stringent measurement tasks in turbines, compressors, and reciprocating machinery, supporting thrust position tracking, ramp differential expansion, tachometer speed detection, and Keyphasor phase reference functions. With its M14 x 1.5 threaded case, Miniature ClickLoc connector, and robust FluidLoc cable structure, the 330703-000-040-10-12-00 model integrates seamlessly into industrial monitoring platforms and automation frameworks. This proximity probe improves stability and measurement repeatability while supporting IP67 dust-water protection, extended -40°C to +85°C operating temperature, and 99.9% copper shielding to reduce electromagnetic interference in demanding factory and petrochemical environments. As an automation component within condition monitoring systems, the 3300 XL 11 mm Proximity Probe supports long-term system reliability, predictive maintenance programs, and operational safety across high-value fluid-film bearing equipment. By leveraging its full-range linearity and precision sensing characteristics, the 330703-000-040-10-12-00 model enables machinery diagnostics, lifecycle monitoring, and smart plant automation with reduced downtime and improved asset productivity.

Applications

Thrust Position Monitoring
Applied on large steam and gas turbines for axial thrust tracking. Utilizes extended linear range to measure displacement values exceeding 2 mm and maintains stable 3.94 V/mm conversion for dynamic load changes.

Differential Expansion Measurement
Used for ramp differential expansion in thermal turbines. Supports precise expansion readings during startup, load transitions, and thermal gradient variations to prevent mechanical interference.

Rod Drop and Rod Position Measurement
Applied on reciprocating compressors for real-time rod displacement monitoring. Enables early detection of rod wear and alignment deviation, reducing unexpected mechanical failure rates by up to 30% in monitored systems.

Zero Speed and Tachometer Measurement
Supports tachometric feedback under low-speed and zero-speed conditions. Enhances industrial speed control loops and shutdown logic for rotating machinery in automated control platforms.

Phase Reference and Keyphasor Signal Acquisition
Provides accurate Keyphasor phase angle reference for vibration analysis. Enables precise FFT spectrum calculation and improves condition-based maintenance accuracy by more than 20% in diagnostic systems.

Specifications
