Quick Detail

Description

The 330851-02-000-070-10-00-05 3300 XL 25 mm Proximity Probe features an M30x2 threaded case with a 70 mm overall length and a 1.0 metre extension cable, designed for automated turbine monitoring. The probe tip is made of PEEK, and the body is AISI 304 stainless steel, capable of operating from -35°C to +200°C and short-term peaks up to +250°C. With a 0.787 V/mm output and 12.7 mm linear range, the 330851-02-000-070-10-00-05 3300 XL 25 mm Proximity Probe measures differential expansion (DE) on steam turbine rotors, using collar or ramp targets. Its 25.4 mm vertical adjustment and ClickLoc connectors simplify alignment and cable routing in tight spaces. Designed to integrate with 3300 XL Proximitor Sensors, the 330851-02-000-070-10-00-05 3300 XL 25 mm Proximity Probe allows retrofits from legacy 7200 DE systems without changing monitor configurations, providing precise DE monitoring and rotor axial movement tracking. Optional flexible SST/PFA armored cables extend installation reach in automated turbine systems, ensuring consistent linear output across the probe’s operational range.
