Quick Detail

Description

The 330851-02-000-060-10-00-CN 3300 XL 25 mm Proximity Probe features an M30x2 threaded stainless steel case (60 mm overall length) and a PEEK probe tip for high-temperature turbine monitoring. With a total length of 1.0 metre (3.3 feet) and 25.4 mm vertical adjustment, the 330851-02-000-060-10-00-CN 3300 XL 25 mm Proximity Probe converts rotor displacement into 0.787 V/mm signals over a 12.7 mm linear range, enabling precise differential expansion measurements. The probe operates from -35°C to +200°C, with short-term tolerance up to 250°C, and integrates with 3300 XL Proximitor Sensors for automated DE monitoring. Front and rear seals, combined with optional flexible SST/PFA cable armor, prevent moisture ingress. ClickLoc connectors with removable collars facilitate routing in confined turbine housings. The 330851-02-000-060-10-00-CN 3300 XL 25 mm Proximity Probe supports multiple mounting configurations, including same-side or complementary input arrangements, providing flexible automation solutions for midsize to large steam turbine generators. Its design allows field replacement of 7200 DE systems without altering monitor configurations, streamlining installation and reducing maintenance downtime.

Applications

Measure Differential Expansion on Steam Turbines
The 330851-02-000-060-10-00-CN 3300 XL 25 mm Proximity Probe monitors rotor-to-stator growth differences on midsize to large steam turbine generators. Its 0.787 V/mm output over 12.7 mm linear range allows precise measurement of axial displacement for turbine DE analysis.

Monitor Rotor Axial Movement
Install the 330851-02-000-060-10-00-CN 3300 XL 25 mm Proximity Probe using same-side or complementary-side mounting on rotor collars or ramps. Its 25.4 mm vertical adjustment ensures accurate tracking of rotor axial travel and compensates for radial shifts.

Automated Condition Monitoring Integration
Pair the 330851-02-000-060-10-00-CN 3300 XL 25 mm Proximity Probe with 3300 XL Proximitor Sensors and extension cables to feed real-time DE and rotor displacement data into automated plant monitoring systems.

Replacement of Legacy 7200 DE Systems
Use the 330851-02-000-060-10-00-CN 3300 XL 25 mm Proximity Probe to replace 7200 25 mm or 35 mm DE probes. It fits multiple mounting arrangements without requiring changes to existing monitor configurations.

Specifications
