Description：

The 3300 XL 50 mm Transducer System consists of a separate50 mm probe, an extension cable, and a 3300 XL 50 mmProximitor Sensor. The large diameter coil gives this system amaximum linear range of 27.9 mm (1100 mils), the longestlinear range of our eddy current transducer line. This linearrange makes the 3300 XL 50 mm Transducer System ideal formeasuring the differential expansion (DE) or rotor expansion(RX) of large steam turbine generators that results from thedifference in growth rates between the turbine rotor and themachine stator (casing).

Product Applications

Power Generation (Steam Turbine Units): Widely used in large, heavy-duty steam turbine generator units in thermal power plants and nuclear power plants. Used for precise monitoring of rotor differential expansion caused by the difference in stator and rotor expansion rates during unit startup and shutdown.

Oil & Gas/Petrochemical Industry: Used in large industrial compressors, heavy-duty gas turbines, and high-pressure units. Capable of stable operation for extended periods under challenging conditions filled with high-temperature steam, preventing serious mechanical accidents caused by excessive rotor axial displacement.

Fluorodynamic Bearing Machinery: Used to monitor fluid-film bearing machinery supported by an oil film, providing both static position and dynamic vibration measurement data.
