Quick Detail

Description

The 330709-00-05-10-12-05 3300 XL 11 mm Proximity Probe is a high-precision non-contact displacement sensor engineered for advanced industrial automation, machinery protection, and condition monitoring systems. Designed to operate as part of the 3300 XL 11 mm proximity transducer system, this proximity probe delivers a stable 3.94 V/mm (100 mV/mil) output, enabling accurate vibration, axial position, and displacement measurement on fluid film bearing machines. With an 11 mm probe tip, the 330709-00-05-10-12-05 proximity probe provides a longer linear measurement range than standard 8 mm probes, making it especially suitable for automation applications requiring extended travel monitoring and higher measurement tolerance.

The 3300 XL 11 mm Proximity Probe features a compact 50 mm overall case length, M16 x 1.5 mounting thread, and a 1.0 meter standard cable equipped with a miniature coaxial ClickLoc connector to ensure secure signal transmission in automated systems. Built with 99.9% braided copper shielding and rated IP67, the probe maintains excellent immunity to electromagnetic interference, dust, oil, and moisture. Operating reliably from -40°C to +85°C, the 330709-00-05-10-12-05 proximity probe is ideal for harsh industrial automation environments such as steam turbines, compressors, and generators. Its robust mechanical design, combined with patented TipLoc and CableLoc technologies, ensures long-term stability, reduced maintenance, and consistent performance in critical automation and protection applications.

Applications

Application 1: Axial Thrust Position Monitoring in Turbomachinery

In turbine and compressor automation systems, the 330709-00-05-10-12-05 3300 XL 11 mm Proximity Probe provides precise axial position measurement using its 3.94 V/mm sensitivity. The extended linear range enables accurate detection of thrust bearing movement, supporting automated protection logic to prevent mechanical damage during transient operating conditions.

Application 2: Differential Expansion Measurement in Steam Turbines

For ramp differential expansion monitoring, the 11 mm proximity probe tracks axial growth differences between the rotor and casing. Compared to 8 mm probes, the longer linear range reduces saturation risk and improves data resolution, enhancing turbine automation reliability during startup and shutdown cycles.

Application 3: Rod Position and Rod Drop Monitoring on Reciprocating Compressors

The 3300 XL 11 mm Proximity Probe is widely used in compressor automation systems to measure rod position and detect rod drop events. The probe’s non-contact measurement capability and IP67 protection ensure consistent performance even in oil-contaminated and high-vibration environments.

Application 4: Tachometer and Zero-Speed Detection

When configured for tachometer or zero-speed measurement, this proximity probe delivers stable pulse signals with minimal noise due to 99.9% copper shielding. Automation controllers rely on this data for accurate speed calculation and safe machinery startup and shutdown sequencing.

Application 5: Phase Reference and Keyphasor Signal Generation

In advanced condition monitoring systems, the 330709-00-05-10-12-05 probe functions as a phase reference sensor. Its fast response and stable output allow precise phase angle tracking, supporting automated vibration analysis and predictive maintenance strategies.
