Quick Detail

Description

The 330851-02-000-060-50-00-CN 3300 XL 25 mm Proximity Probe is a high-precision transducer designed for automated monitoring of differential expansion in midsize to large steam turbine generators. Featuring a 60 mm overall case length, M30x2 threaded housing, and a 25.4 mm vertical probe adapter adjustment, the 330851-02-000-060-50-00-CN 3300 XL 25 mm Proximity Probe provides a linear output of 0.787 V/mm over a 12.7 mm range. Constructed with AISI 304 stainless steel and a PEEK tip, this probe operates continuously from -35°C to +200°C and handles short-term spikes up to 250°C. With a 5.0 metre total length and optional flexible SST/PFA armored extension cable, the 330851-02-000-060-50-00-CN 3300 XL 25 mm Proximity Probe supports installation in long-distance monitoring applications. Its front and rear seals, combined with high-temperature ClickLoc connectors, prevent moisture ingress and facilitate routing through tight turbine clearances. Compatible with 3300 XL Proximitor Sensors, this probe integrates seamlessly into automated condition monitoring systems and can replace legacy 7200 DE probes without reconfiguring monitors, ensuring precise rotor-to-stator axial displacement tracking in steam turbines.
