Bently Nevada 330703-000-040-90-02-CN 3300 11 mm Transducer System Proximity Probe

Bently 3300XL 330851-02-000-070-50-00-CN/05 is a differential expansion sensor part of the Bently 3300 XL 25 mm system, consisting of a 25 mm probe, extension cable, and 3300 XL 25 mm proximitor. With a 0.787 V/mm (20 mV/mil) output, it offers a 12.7 mm (500 mil) linear range—ideal for measuring differential expansion (DE) in medium-to-large steam turbine generators, caused by differing expansion rates between rotor and stator. The DE measurement is achieved via two eddy current sensors, targeting flanges or inclined surfaces at a distance from the thrust bearing.
