Description
The 330851-04-000-023-10-01-05 3300 XL 25 mm Proximity Probe provides precise differential expansion measurement for steam turbine generators. Featuring a smooth 1.06 in. diameter side-exit case, 230 mm overall length, and 1.0 m SST-armored extension cable, the 330851-04-000-023-10-01-05 operates from –35°C to +200°C continuously and withstands up to 250°C short-term. Constructed from AISI 304 stainless steel with a PEEK tip, it delivers 0.787 V/mm (20 mV/mil) output over a 12.7 mm linear range and 25.4 mm vertical adjustment for precise rotor collar or ramp alignment. High-temperature ClickLoc connectors with FluidLoc cables prevent fluid ingress. The 330851-04-000-023-10-01-05 supports automated turbine monitoring, including axial movement, rod position, and differential expansion measurements, while SpringLoc terminal strips on the Proximitor Sensor enable fast, robust field wiring.
Applications
Measure Differential Expansion on Steam Turbines
Use the 330851-04-000-023-10-01-05 to monitor rotor collars and ramps, providing 0.787 V/mm signals for automated DE analysis.
Track Rotor Axial Movement
Connect the 330851-04-000-023-10-01-05 to measure rotor displacement. Its 25.4 mm vertical adjustment ensures precise probe positioning.
Verify Probe Alignment Using Sliding Bracket
Mount the 330851-04-000-023-10-01-05 on a 3300 XL Sliding Bracket to simulate shaft collar motion and adjust probe gap across the 12.7 mm linear range.
