Quick Detail

Description

The 330851-08-000-064-10-01-05 3300 XL 25 mm Proximity Probe features a smooth 1.5 in diameter side-exit case with a 64 mm overall length and 1.0 metre extension cable, equipped with SST armor. Its 0.787 V/mm (20 mV/mil) output provides a 12.7 mm linear range, enabling precise measurement of differential expansion (DE) in midsize to large steam turbines. The 330851-08-000-064-10-01-05 3300 XL 25 mm Proximity Probe operates continuously from -35°C to +200°C and tolerates short-term temperatures up to +250°C. With a 25.4 mm probe adapter vertical adjustment and PEEK tip, it monitors rotor-to-stator axial movement and supplies real-time data to automation systems. The probe’s front and rear seals, combined with high-temperature ClickLoc connectors, ensure reliable signal integrity while routing cables through tight turbine spaces. Designed to replace legacy 7200 and 3300 XL 25 mm transducer systems, the 330851-08-000-064-10-01-05 3300 XL 25 mm Proximity Probe supports seamless upgrades and accurate DE measurement without changes to existing monitor configurations.

Applications

Differential Expansion Measurement on Steam Turbines
The 330851-08-000-064-10-01-05 3300 XL 25 mm Proximity Probe measures rotor-to-stator growth differences in midsize to large steam turbines. Its 12.7 mm linear range and 0.787 V/mm output allow precise tracking of axial movement between collars and ramps, providing accurate DE data for automation systems.

Rotor Position Monitoring in Turbine Generators
With a 25.4 mm vertical adjustment and 1.0-metre cable, the 330851-08-000-064-10-01-05 3300 XL 25 mm Proximity Probe captures rotor motion in real time. Automation systems use this data to control shaft alignment and prevent mechanical contact.

High-Temperature Operational Feedback
The 330851-08-000-064-10-01-05 3300 XL 25 mm Proximity Probe operates continuously up to +200°C and withstands short-term peaks of +250°C, enabling it to feed thermal expansion data into predictive maintenance programs in steam turbine environments.

Retrofit for Legacy 7200 Systems
The 330851-08-000-064-10-01-05 3300 XL 25 mm Proximity Probe physically replaces older 7200 25 mm or 35 mm DE transducer systems. Automation systems can upgrade to modern 3300 XL sensors without reconfiguring monitor setups, reducing downtime.
