Quick Detail

Description

The 330851-02-000-030-10-00 3300 XL 25 mm Proximity Probe features an M30x2 threaded 30 mm case with a 1.0-meter standard cable, providing precise non-contact vibration and displacement measurements on large steam turbine rotors. Its 25 mm probe tip and 0.787 V/mm output enable a 12.7 mm linear range, ideal for measuring differential expansion (DE) between rotor and stator. The 330851-02-000-030-10-00 3300 XL 25 mm Proximity Probe operates continuously up to 200°C and withstands short-term exposure to 250°C, with front and rear seals and FluidLoc cable preventing moisture ingress. High-temperature ClickLoc connectors and optional connector protectors ensure reliable signal transfer in automated monitoring systems. The 330851-02-000-030-10-00 3300 XL 25 mm Proximity Probe replaces all standard 7200 25 mm and 35 mm DE transducers, allowing direct upgrades without monitor changes. Available with multiple probe case styles and locknut safety features, the 330851-02-000-030-10-00 3300 XL 25 mm Proximity Probe supports automated alignment and gap verification using optional 3300 XL Sliding Brackets.

Applications

Measure axial expansion between rotor and stator
Use 330851-02-000-030-10-00 3300 XL 25 mm Proximity Probe to track differential expansion (DE) of steam turbine generators. Its 12.7 mm linear range allows accurate detection of rotor and stator displacement, even during high-temperature operation up to 200°C.

Monitor thrust collar movement
Install 330851-02-000-030-10-00 3300 XL 25 mm Proximity Probe on thrust collars to capture precise axial positions. Front and rear seals with FluidLoc cable prevent moisture entry, ensuring reliable automated measurements.

Track rotor radial movement
Place multiple 330851-02-000-030-10-00 3300 XL 25 mm Probes at strategic points around the rotor. The 0.787 V/mm output and 25.4 mm vertical adjustment support accurate real-time monitoring of radial displacement for automated feedback systems.

Upgrade legacy 7200-series systems
Replace 7200-series DE transducers with 330851-02-000-030-10-00 3300 XL 25 mm Probes without modifying existing monitor wiring. The probe output matches previous systems, simplifying integration into current automation setups.
