The Bently Nevada 330876-02-10-00-00 3300 XL 50 mm Transducer System is a 50mm eddy current transducer system with a 27.9mm linear range, ideal for measuring differential expansion in large steam turbines. It includes a probe, extension cable, and Proximitor sensor.

Key Applications

Differential Expansion (DE) Measurement: Specifically designed for measuring DE in large steam turbine generators.

Rotor Expansion (RX) Monitoring: Ideal for tracking rotor growth relative to the machine stator.

Long-Range Measurement: Its 27.9mm linear range suits applications requiring extensive measurement capability.

Single-Side Collar Observation: Preferred for redundant measurements on the same side of a collar when range is below 27.9mm.

Complementary Mounting Configuration: Enables measurement of ranges from 28mm to 56mm when installed on opposite sides of a collar.

Large Steam Turbine Monitoring: The primary application is monitoring thermal growth in critical large turbine assets.

FAQ

Q1: What is the primary application of this transducer system?

A1: It is primarily used for measuring Differential Expansion (DE) or Rotor Expansion (RX) in large steam turbine generators.

Q2: What is its key technical advantage?

A2: It offers the longest linear range (27.9 mm / 1100 mils) in the eddy current transducer line for extensive measurement capability.

Q3: What does the system include?

A3: The system consists of a separate 50 mm probe, an extension cable, and a 3300 XL 50 mm Proximitor Sensor.

Q4: What are the two main mounting configurations for DE measurement?

A4: The two configurations are mounting two transducers on the same side of a collar, or in a complementary fashion on opposite sides for a doubled range.

Q5: What is the model number for this 50 mm transducer system?

A5: The product model is 330876-02-10-00-00.
