Quick Detail

Description

The 330851-02-000-050-50-01-CN 3300 XL 25 mm Proximity Probe is a precision transducer for automated turbine monitoring. Featuring a 50 mm AISI 304 stainless steel case, PEEK tip, and optional SST armor, the 330851-02-000-050-50-01-CN 3300 XL 25 mm Proximity Probe provides reliable differential expansion measurement with 0.787 V/mm output over a 12.7 mm linear range. Its 1.0 m extension cable and ClickLoc connectors allow flexible installation in tight turbine housings. The probe supports M30x2 thread mounting, 25.4 mm vertical adjustment, and operation from -35°C to +200°C, with short-term tolerance to +250°C. Designed for integration with 3300 XL Proximitor Sensors, the 330851-02-000-050-50-01-CN 3300 XL 25 mm Proximity Probe automates real-time rotor-to-stator monitoring, shaft alignment verification, and system upgrades from 7200 DE transducers without monitor recalibration. Moisture-resistant seals and armored cable options ensure continuous operation in harsh steam turbine environments, enhancing automated data collection and maintenance efficiency.

Applications

Measure Differential Expansion on Turbine Rotors
The 330851-02-000-050-50-01-CN 3300 XL 25 mm Proximity Probe measures axial movement between turbine rotor and stator. Two probes can be mounted on the same collar or on complementary ramps to capture full differential expansion (DE) range up to 12.7 mm, ensuring accurate automation of turbine DE data.

Monitor Rotor Shaft Alignment in Real Time
By combining the 330851-02-000-050-50-01-CN 3300 XL 25 mm Proximity Probe with Proximitor Sensors, operators can automatically track rotor movement along the shaft, reducing manual inspections and enabling automated data logging for predictive maintenance.

Upgrade Existing Turbine Sensors
The 330851-02-000-050-50-01-CN 3300 XL 25 mm Proximity Probe replaces standard 7200 25 mm and 35 mm DE integral systems without modifying monitor configurations, allowing automated retrofitting and real-time integration.

High-Temperature Steam Turbine Monitoring
With SST armor and fluid-tight seals, the 330851-02-000-050-50-01-CN 3300 XL 25 mm Proximity Probe continuously operates up to 200°C, and withstands short-term spikes up to 250°C, enabling automated measurements in harsh turbine environments.
