Quick Detail

Description

The 330851-02-000-030-10-00-05 3300 XL 25 mm Proximity Probe is designed for automated measurement of differential expansion (DE) in midsize to large steam turbine generators. With an M30x2 probe thread, 30 mm overall case length, and linear range of 12.7 mm, 330851-02-000-030-10-00-05 converts axial shaft and rotor movement into 0.787 V/mm (20 mV/mil) output for monitoring and control.

The 330851-02-000-030-10-00-05 probe operates from −35°C to +200°C continuously, with short-term exposure up to 250°C, allowing installation near high-temperature turbine bearings. The PEEK probe tip and AISI 304 stainless steel case maintain accurate measurements under harsh DE environments. Standard 1-meter extension cable with high-temperature ClickLoc connectors and FluidLoc design prevents moisture ingress and facilitates routing through tight spaces.

330851-02-000-030-10-00-05 is compatible with 3300 XL 25 mm Proximitor Sensors and can replace older 7200 25 mm or 35 mm DE transducer systems without monitor changes. Adjustable probe adapters with 25.4 mm vertical travel allow precise alignment with turbine collars or ramps, supporting automated differential expansion measurement, shaft motion tracking, and rotor-stator alignment monitoring in high-temperature and high-precision industrial environments.

Applications

Measure differential expansion on steam turbine rotors
330851-02-000-030-10-00-05 monitors axial shaft movement on midsize to large turbine generators. With a linear range of 12.7 mm and 0.787 V/mm output, 330851-02-000-030-10-00-05 converts rotor-stator relative movement into precise voltage signals for automation and control systems.

Monitor shaft motion in high-temperature turbine bearings
Rated for continuous operation from −35°C to +200°C and short-term exposure to 250°C, 330851-02-000-030-10-00-05 delivers accurate measurements near high-temperature bearings and steam passages, supporting real-time automated DE tracking.

Provide differential expansion measurement using collar or ramp targets
The 30 mm overall case length, M30x2 probe thread, and adjustable probe adapter with 25.4 mm vertical travel allow 330851-02-000-030-10-00-05 to align precisely with collars or ramps for automated axial displacement monitoring.

Integrate with 3300 XL 25 mm Proximitor Sensors
330851-02-000-030-10-00-05 connects to 3300 XL 25 mm Proximitor Sensors using 1-meter standard cables with high-temperature ClickLoc connectors, providing reliable voltage output for control and diagnostic systems.

Specifications

Competitive Advantage

Supports large linear range measurements
330851-02-000-030-10-00-05 provides 12.7 mm linear range (0.787 V/mm) allowing DE measurements on large turbines without exceeding probe limits.

Handles high-temperature industrial environments
Continuous operation up to 200°C and short-term exposure to 250°C ensures 330851-02-000-030-10-00-05 functions near hot bearings while maintaining accurate displacement readings.

Prevents moisture ingress in harsh conditions
FluidLoc cable design and PEEK probe tip on 330851-02-000-030-10-00-05 prevent oil or moisture from entering the probe, supporting long-term automated monitoring.

Simplifies installation and alignment
Adjustable probe adapters with 25.4 mm vertical travel allow 330851-02-000-030-10-00-05 to be precisely positioned on turbine collars or ramps, facilitating installation and periodic verification.
