Description
The 330851-02-000-050-10-01-05 3300 XL 25 mm Proximity Probe is designed for automated monitoring of differential expansion (DE) in midsize to large steam turbines. Featuring a 50 mm overall case length, M30x2 stainless steel case, and 25.4 mm probe adapter travel, the 330851-02-000-050-10-01-05 3300 XL 25 mm Probe delivers 0.787 V/mm output over a 12.7 mm linear range. Equipped with armored AISI 304 SST and a PEEK tip, this probe operates continuously from -35°C to +200°C and intermittently up to 250°C, ensuring reliable automated DE measurements. The 330851-02-000-050-10-01-05 3300 XL 25 mm Probe comes with front and rear seals and optional FluidLoc armored cable to prevent moisture ingress, maintaining signal integrity in turbine environments. High-temperature ClickLoc connectors simplify field installation and routing through tight spaces. Compatible with 7200-series DE systems, the 330851-02-000-050-10-01-05 3300 XL 25 mm Probe supports single or complementary input setups, side or rear exit mounts, and DIN-rail or panel mounting for automated data acquisition. Its precision linear output and robust design enable accurate gap measurement, rotor displacement monitoring, and continuous turbine performance tracking.
Applications
Measure differential expansion on steam turbines
Use 330851-02-000-050-10-01-05 3300 XL 25 mm Proximity Probe to track axial growth differences between turbine rotors and stators. The 12.7 mm linear range and 0.787 V/mm output allow precise automated detection of DE across 1.0 metre armored cables.
Monitor rotor displacement in real-time
Install 330851-02-000-050-10-01-05 3300 XL 25 mm Proximity Probe on the rotor or collar to measure axial or radial movements. The M30x2 stainless steel case and 25.4 mm probe travel provide repeatable readings for automated turbine control systems.
Enable automated shaft gap verification
Deploy 330851-02-000-050-10-01-05 3300 XL 25 mm Proximity Probe in complementary input setups with side or rear exit mounts to automate the verification of shaft-to-collar clearance over the full linear range.
Support turbine performance data acquisition
Integrate 330851-02-000-050-10-01-05 3300 XL 25 mm Proximity Probe with 3300 XL Proximitor Sensors and extension cables to feed continuous displacement and DE measurements into plant control software.

Competitive Advantage
Operate in extreme temperatures
The 330851-02-000-050-10-01-05 3300 XL 25 mm Proximity Probe maintains linear output and accuracy from -35°C to +200°C, with short-term exposure up to +250°C, ensuring reliable automated DE measurements in high-temperature turbine environments.
Prevent moisture ingress for uninterrupted monitoring
Front and rear seals combined with armored SST cable and optional FluidLoc design in 330851-02-000-050-10-01-05 3300 XL 25 mm Proximity Probe prevent oil or moisture from entering the probe tip, keeping automated data collection continuous.
Simplify installation and probe routing
ClickLoc connectors and removable collars on 330851-02-000-050-10-01-05 3300 XL 25 mm Proximity Probe allow quick connections and easy cable routing through tight turbine casing spaces, facilitating faster automated system integration.
Support automated verification and calibration
Combined with optional 3300 XL Sliding Brackets, 330851-02-000-050-10-01-05 3300 XL 25 mm Proximity Probe allows automated calibration by sliding the probe along its full 25.4 mm travel, verifying axial and radial rotor measurements without manual adjustments.
