High-Performance Differential Expansion Sensor for Large Turbomachinery

The Bently Nevada 330876-02-90-01-00 3300 XL 50 mm Eddy-Current Probe is a heavy-duty non-contact transducer designed for precise measurement of shaft displacement, vibration, and differential expansion in large rotating machinery. As part of the 3300 XL 50 mm transducer system, it is engineered specifically for steam turbines, hydro turbines, compressors, and large generator applications where long-range, high-stability measurement is required.

This probe is optimized for harsh industrial environments where temperature fluctuations, vibration, and long cable runs demand exceptional signal stability and mechanical durability. It provides reliable continuous monitoring, making it a core component in turbine supervisory instrumentation and predictive maintenance systems.

Technical FAQs

1. What is the main function of this probe?

It measures shaft position, vibration, and differential expansion in large rotating machines.

2. Why is a 50 mm probe used?

It provides a longer linear measurement range suitable for turbine-scale motion.

3. Does this probe work alone?

No, it must be used with a compatible extension cable and Proximitor® sensor.

4. What does the “90” code usually indicate?

It typically corresponds to a long cable configuration (commonly around 9 meters).

5. Is this probe suitable for steam turbines?

Yes, it is specifically designed for steam turbine DE applications.

6. Can it handle high temperatures?

Yes, it supports continuous high-temperature turbine environments.

7. Is it a contact-based sensor?

No, it uses eddy-current non-contact measurement.

8. What industries use this probe?

Power generation, oil & gas, petrochemical, marine, and heavy industry.

9. Is it suitable for continuous operation?

Yes, it is designed for 24/7 monitoring systems.

10. What is the benefit of the 3300 XL system?

It provides high-accuracy, long-range vibration and displacement monitoring for critical assets.
