Quick Detail

Description

The 330876-02-50-00 3300 XL 50 mm Proximity Probe is designed for automated differential expansion (DE) and rotor expansion (RX) monitoring in large steam turbine generators. Featuring a 50 mm coil with M14x1.5 threaded AISI 304 stainless steel case and PPS probe tip, the 330876-02-50-00 3300 XL 50 mm Proximity Probe delivers a linear range of 27.9 mm (1100 mils) with 0.394 V/mm output. The probe operates from -35°C to +200°C, with short-term exposure up to 250°C, and integrates with high-temperature FluidLoc armored cables and ClickLoc connectors for precise measurements. Total system length of 5.0 meters allows flexible positioning, while shielded triad cables simplify field wiring. Compatible with 3300 XL 50 mm Proximitor Sensors, the 330876-02-50-00 3300 XL 50 mm Proximity Probe replaces legacy 7200 50 mm systems without requiring monitor modifications. Straight or side exit probe styles, locknuts with predrilled safety wire holes, and flexible armored cables support automated installation and reliable operation in challenging turbine environments.

Applications

Differential Expansion Monitoring
Use the 330876-02-50-00 3300 XL 50 mm Proximity Probe to measure turbine differential expansion (DE) by mounting two probes on the same or opposite sides of a turbine collar. The 27.9 mm linear range of the 330876-02-50-00 3300 XL 50 mm Proximity Probe enables precise automated detection of rotor-stator growth under continuous operation from -35°C to +200°C.

Rotor Expansion Measurement
Install the 330876-02-50-00 3300 XL 50 mm Proximity Probe on rotor ramps to measure axial and radial rotor movement. With a 0.394 V/mm output and total system length up to 5.0 meters, the 330876-02-50-00 3300 XL 50 mm Proximity Probe ensures accurate automated rotor expansion tracking.

High-Temperature Turbine Environments
Deploy the 330876-02-50-00 3300 XL 50 mm Proximity Probe for continuous readings in environments up to 200°C and short-term spikes to 250°C. Its PPS probe tip and AISI 304 stainless steel case, combined with FluidLoc armored cables, allow automated operation in extreme conditions without signal loss.

Legacy System Upgrades
Replace existing 7200 50 mm systems with 330876-02-50-00 3300 XL 50 mm Proximity Probe and 3300 XL Proximitor Sensors. The 0.394 V/mm output and M14x1.5 threaded probe case allow automated integration without monitor reconfiguration.
