Quick Detail

Description

The 330851-02-000-050-10-00-05 3300 XL 25 mm Proximity Probe features an M30x2 stainless steel case with a 50 mm overall length and a PEEK probe tip for high-temperature turbine monitoring. Its 0.787 V/mm output delivers a 12.7 mm linear range, ideal for measuring differential expansion (DE) between rotors and casings on midsize to large steam turbine generators. The 330851-02-000-050-10-00-05 3300 XL 25 mm Probe integrates with extension cables up to 1.0 m and optional FluidLoc or armored cables for moisture protection. Front and rear seals, combined with high-temperature ClickLoc connectors, secure automated signal transmission in environments up to 200°C continuously and 250°C intermittently. The probe supports single and complementary input configurations, allowing axial and radial displacement monitoring. With predrilled locknuts, vertical adjustment of 25.4 mm, and compatibility with 7200-series 25 mm and 35 mm DE probes, the 330851-02-000-050-10-00-05 3300 XL 25 mm Probe enables straightforward automated upgrades and precise DE measurement. Connector protectors and the optional sliding bracket simplify installation, verification, and maintenance of automated monitoring systems while maintaining accurate, repeatable readings.

Applications

Application: Measure Differential Expansion on Steam Turbines

The 330851-02-000-050-10-00-05 3300 XL 25 mm Proximity Probe, with a 12.7 mm linear range and 0.787 V/mm output, monitors axial movement between turbine rotors and casings. Its M30x2 stainless steel case and PEEK tip allow precise measurement of rotor-casing growth differences during operation.

Application: Monitor Axial Shaft Displacement

Using its 25.4 mm vertical adjustment and 50 mm overall case length, the 330851-02-000-050-10-00-05 3300 XL 25 mm Probe detects shaft movement along the axial direction. Integration with extension cables up to 1.0 m ensures automated continuous signal capture.

Application: Implement Complementary Input DE Measurement

The 330851-02-000-050-10-00-05 3300 XL 25 mm Probe supports two-transducer complementary input setups to double the measurable DE range. Front and rear seals combined with optional FluidLoc or armored cables prevent moisture ingress, ensuring accurate readings.

Application: Upgrade Existing 7200-Series DE Systems

This 330851-02-000-050-10-00-05 3300 XL 25 mm Probe replaces 7200-series 25 mm and 35 mm DE transducers without monitor configuration changes. High-temperature ClickLoc connectors and predrilled locknuts allow automated retrofits with minimal downtime.
