Product Overview
Description
The 330707-00-20-10-12-00 3300 XL 11 mm Proximity Probe is a high-performance non-contact displacement sensor engineered for critical industrial automation and rotating machinery protection systems. Designed for seamless integration with the 3300 XL Proximity Transducer System, this 11 mm proximity probe delivers a calibrated output of 3.94 V/mm (100 mV/mil), enabling highly accurate vibration, position, and displacement measurements in fluid film bearing machines.
Compared with standard 8 mm probes, the 3300 XL 11 mm proximity probe provides an extended linear measurement range, making it ideal for axial thrust monitoring, differential expansion tracking, and rod position measurement in large-scale turbines and compressors. The probe features a 5/8-18 UNF threaded case, 1.0 m FluidLoc cable, and a miniature coaxial ClickLoc connector, ensuring secure signal transmission and long-term stability in harsh automation environments. With IP67 environmental protection, 99.9% braided copper shielding, and an operating temperature range of -40°C to +85°C, the 330707-00-20-10-12-00 proximity probe supports continuous, reliable operation in demanding industrial automation and condition monitoring applications.
Key Functions
Applications
Axial Thrust Position Monitoring in Steam Turbines
In large steam turbines, axial shaft movement must be tightly controlled to avoid thrust bearing damage. The 3.94 V/mm sensitivity and long linear range of the 3300 XL 11 mm proximity probe allow precise detection of axial displacement exceeding ±2 mm, supporting real-time protection and automated shutdown logic.
Differential Expansion Measurement
For high-temperature turbine casings, differential expansion between rotor and casing is critical. With a 1.0 m probe length and stable output across -40°C to +85°C, this proximity probe ensures consistent measurements during cold starts and thermal ramp-up sequences.
Rod Position and Rod Drop Detection in Reciprocating Compressors
The 11 mm probe tip enables accurate rod position monitoring even with large mechanical tolerances. Its non-contact sensing prevents mechanical wear while providing reliable displacement feedback for compressor automation systems.
Tachometer and Zero-Speed Detection
When configured with appropriate targets, the probe supports speed and zero-speed detection. The fast response and low noise enabled by 99.9% copper shielding ensure stable tachometer signals for automated startup and shutdown sequences.
Phase Reference (Keyphasor) Signal Generation
In rotating machinery diagnostics, phase reference accuracy is essential. The probe’s stable output and ClickLoc connector design ensure repeatable Keyphasor signals for vibration phase analysis within advanced condition monitoring platforms.

Compatibility & Ordering Notes
Competitive Advantage
Extended Linear Range for Large Machinery
Compared to 8 mm proximity probes, the 11 mm sensing tip provides a longer usable linear range, reducing saturation risk and improving measurement accuracy in large turbines and compressors.
Industrial-Grade Environmental Protection
With IP67-rated sealing, the probe resists dust, oil, and water ingress, making it suitable for harsh automation environments such as power plants and petrochemical facilities.
Superior Signal Integrity
The 99.9% braided copper shielding significantly reduces electromagnetic interference, improving signal-to-noise ratio and ensuring accurate displacement readings in high-EMI industrial systems.
Secure Mechanical and Electrical Design
The 5/8-18 UNF thread, locknut with safety wire holes, and ClickLoc connector prevent loosening due to vibration, enhancing long-term reliability in continuous-duty machinery.
Seamless Upgrade Path within 3300 XL Systems
Designed as a direct replacement for legacy 7200-series systems, the 3300 XL 11 mm proximity probe enables modernization of automation monitoring systems while maintaining compatibility with updated 3300 and 3500 monitoring platforms.
