Heavy-Duty Differential Expansion Monitoring for Large Turbomachinery
The Bently Nevada 330851-04-00-60-10-01-05 3300 XL 25 mm Proximity Transducer Assembly is a high-performance industrial sensing solution engineered for accurate differential expansion, shaft position, and vibration measurements on large rotating equipment.
As part of the 3300 XL 25 mm Transducer System, this assembly is specifically designed for steam turbine generators, compressors, and critical machinery operating under demanding temperature and environmental conditions. The system combines a 25 mm proximity probe, extension cable, and 3300 XL Proximitor® sensor to deliver stable measurements over extended operating periods. The 3300 XL 25 mm system is widely used for differential expansion monitoring on mid-size to large steam turbine generators.
