Quick Detail

Description

The 330851-02-000-066-10-00-05 3300 XL 25 mm Proximity Probe is a precision transducer designed for automated differential expansion monitoring in midsize to large steam turbine generators. Featuring a 66 mm overall case length, M30x2 threaded housing, and 25.4 mm vertical probe adjustment, the 330851-02-000-066-10-00-05 3300 XL 25 mm Proximity Probe provides a linear output of 0.787 V/mm across a 12.7 mm range. Constructed from AISI 304 stainless steel with a PEEK tip, it operates continuously from -35°C to +200°C and handles short-term peaks up to 250°C. The 1.0 metre probe length allows installation near turbine thrust bearings, while optional flexible SST/PFA armored extension cables ensure secure signal transmission. Front and rear seals plus high-temperature ClickLoc connectors prevent moisture ingress and facilitate routing in tight spaces. Fully compatible with 3300 XL Proximitor Sensors, the 330851-02-000-066-10-00-05 3300 XL 25 mm Proximity Probe replaces legacy 7200 DE probes without monitor modifications, supporting accurate automated monitoring of rotor-to-stator axial displacement.

Applications

Measure Differential Expansion on Steam Turbines
The 330851-02-000-066-10-00-05 3300 XL 25 mm Proximity Probe accurately monitors rotor-to-stator expansion on midsize to large steam turbines using its 0.787 V/mm output and 12.7 mm linear range. Its M30x2 threaded probe and 25.4 mm vertical adjustment allow precise alignment on collars or ramps near thrust bearings.

Monitor Axial Rotor Movement
Use the 330851-02-000-066-10-00-05 3300 XL 25 mm Proximity Probe to track rotor axial displacement during operation. The 66 mm case length and 1.0 metre cable length provide flexibility to reach difficult locations while maintaining signal integrity.

Integrate with Proximitor Sensor Systems
The 330851-02-000-066-10-00-05 3300 XL 25 mm Proximity Probe works seamlessly with 3300 XL Proximitor Sensors, replacing legacy 7200 DE systems without reconfiguring monitors, allowing automated turbine monitoring and retrofit upgrades.

High-Temperature DE Measurement
With operating ranges from -35°C to +200°C and short-term peaks up to 250°C, the 330851-02-000-066-10-00-05 3300 XL 25 mm Proximity Probe is suitable for turbine environments experiencing rapid thermal changes.
