Quick Detail

Description

The 330876-02-10-00-00 3300 XL 50 mm Proximity Probe forms part of the 3300 XL 50 mm Transducer System, which includes a 50 mm probe, extension cable, and a 3300 XL 50 mm Proximitor Sensor. With a 27.9 mm (1100 mils) linear range and 0.394 V/mm output, the 330876-02-10-00-00 3300 XL 50 mm Proximity Probe measures differential expansion (DE) or rotor expansion in large steam turbine generators. The probe features an M14x1.5 thread case, PPS probe tip, and AISI 304 stainless steel body, with high-temperature FluidLoc cable armor supporting -35°C to +200°C operation and short-term peaks up to +250°C. The 330876-02-10-00-00 3300 XL 50 mm Proximity Probe accepts 0.2–1.5 mm² field wiring and integrates with legacy 7200 50 mm DE systems. Front and rear seals combined with ClickLoc high-temperature connectors ensure moisture-free operation, while the probe’s design allows side or straight exit installation with locknut safety wire holes. The 330876-02-10-00-00 3300 XL 50 mm Proximity Probe provides long-range, precise measurement for automated turbine monitoring, rotor alignment checks, and differential expansion data collection in industrial control systems.

Applications

Measuring Differential Expansion on Steam Turbines
The 330876-02-10-00-00 3300 XL 50 mm Proximity Probe measures rotor-to-stator growth differences using its 27.9 mm (1100 mils) linear range and 0.394 V/mm output. Two probes observing opposite sides of a collar provide extended DE measurements for large steam turbine generators.

Rotor Expansion Monitoring
With its M14x1.5 threaded case and high-temperature PPS tip, the 330876-02-10-00-00 3300 XL 50 mm Proximity Probe tracks rotor axial movement and expansion under high heat (up to 200°C continuous, 250°C short-term).

Automated Turbine Gap Verification
The 330876-02-10-00-00 3300 XL 50 mm Proximity Probe integrates with DIN-rail or panel-mounted Proximitor Sensors to automate DE and rotor alignment checks, ensuring precise gap measurement and reporting in control systems.

Integration with Legacy 7200 Systems
The 330876-02-10-00-00 3300 XL 50 mm Proximity Probe can replace standard 7200 50 mm transducers, maintaining output consistency while enabling automated upgrades without monitor reconfiguration.

Specifications

Competitive Advantage

Extended Linear Measurement
The 330876-02-10-00-00 3300 XL 50 mm Proximity Probe offers the longest linear range in the eddy-current 50 mm line (27.9 mm), enabling accurate measurement of large rotor expansions.

High-Temperature Endurance
The 330876-02-10-00-00 3300 XL 50 mm Proximity Probe operates reliably from -35°C to +200°C, surviving short-term peaks to 250°C, making it ideal for high-heat turbine environments.

Rapid Field Installation
The 330876-02-10-00-00 3300 XL 50 mm Proximity Probe supports straight or side exit mounting with ClickLoc connectors and locknut safety wire holes, allowing fast, precise installation in automated monitoring systems.

Direct Sensor Upgrade
Replacing old 7200 systems with the 330876-02-10-00-00 3300 XL 50 mm Proximity Probe avoids changes in Proximitor Sensor wiring or monitoring software, reducing downtime and simplifying automation integration.
