Product Description
The Bently Nevada 330850-91-05 is part of the 3300 XL 25 mm Proximity Transducer System, optimized for monitoring differential expansion (DE) in mid to large steam turbine generators. The system includes a 25 mm proximity probe, extension cable, and Proximitor sensor, designed to deliver precise non-contact measurement over a linear range of 12.7 mm.
Applications
-
Steam turbines: DE measurement between rotor and stator
-
Turbine generators: Rotor axial displacement tracking
-
High-temperature industrial environments: Up to 200°C continuous operation
-
Complementary and single transducer DE setups
Advantages
-
Long linear range: 12.7 mm (500 mils) for extended measurement
-
High temperature tolerance: Up to 200°C continuous, 250°C short term
-
Interchangeable upgrade path: Fully compatible with legacy 7200 series
-
Robust build: Stainless steel casing, sealed probe tip with PFA-insulated FluidLoc cables
-
Flexible installation: DIN-rail or panel mountable sensor
