Description
The 330851-02-000-066-10-00-00 3300 XL 25 mm Proximity Probe is designed for differential expansion (DE) measurement on midsize to large steam turbine generators. The probe features an M30x2 thread, 66 mm overall case length, 1.0 meter (3.3 ft) cable, AISI 304 stainless steel case, and PEEK probe tip. With a 0.787 V/mm (20 mV/mil) output and 12.7 mm (500 mils) linear range, the 330851-02-000-066-10-00-00 3300 XL 25 mm Proximity Probe accurately measures axial movement caused by rotor and casing growth differences. It operates from -35°C to +200°C (-31°F to +392°F) and withstands short-term temperatures up to 250°C (482°F). Flexible FluidLoc cables, high-temperature ClickLoc connectors, and front/rear seals maintain signal integrity for automated turbine monitoring systems.
Applications
Differential Expansion Measurement: The 330851-02-000-066-10-00-00 3300 XL 25 mm Proximity Probe measures rotor-casing axial growth differences with 12.7 mm linear range and 0.787 V/mm output, providing real-time data for automated control systems.
Redundant Axial Monitoring: Two probes on the same collar side allow precision DE tracking, reducing gaps in automated turbine monitoring.
Complementary DE Input Measurement: Paired probes observing opposite collar sides double DE measurement range; 1.0 meter cable allows flexible routing in confined automation layouts.
High-Temperature Operation: Continuous 200°C operation with short-term 250°C tolerance ensures accurate data even during high-temperature transients.
Flexible Mounting Options: M30x2 thread and 25.4 mm vertical probe adjustment allow precise installation in limited spaces or complex machinery automation setups.

Competitive Advantage
Precision Axial Tracking: 12.7 mm linear range and 0.787 V/mm output deliver highly accurate differential expansion data for automated turbine control.
Robust Signal Protection: PEEK probe tip, front/rear sealing, and FluidLoc cable prevent moisture ingress and maintain signal integrity for automated monitoring.
High-Temperature Capability: Operates at 200°C continuously and 250°C short-term, suitable for harsh steam turbine DE applications.
Installation Flexibility: Multiple case styles, side/rear exit options, and vertical adjustment enable mounting in restricted or complex automation environments.
Seamless System Upgrade: Compatible with legacy 7200-series 25 mm and 35 mm DE probes, allowing direct replacement without modifying existing monitoring configurations.
