Bently Nevada 330851-02-000-050-90-00-00 3300 XL 25 mm Proximity Probe

Applications

The Bently Nevada 3300 XL 25 mm proximity probe with 9-meter total length is intended for large industrial installations where sensing points are located far from monitoring systems or control cabinets.

It is widely used in steam turbines, hydro turbines, compressors, generators, and other heavy rotating machinery across power generation, oil and gas, and petrochemical industries. In turbine systems, it provides continuous shaft vibration and axial displacement monitoring. In large compressor trains and pump systems, it supports early detection of mechanical issues such as imbalance, misalignment, and bearing degradation.

It is also widely applied in distributed condition monitoring architectures where sensors are installed across large plant areas and signal routing must remain stable over long distances.

Advantages

This proximity probe is engineered to maintain stable measurement performance even across extended cable lengths, ensuring reliable signal transmission in large industrial systems.

It delivers high linearity eddy current sensing, enabling accurate vibration and displacement measurement under continuous operation. The probe design provides strong electromagnetic interference resistance, making it suitable for high-noise environments such as turbine halls and power stations.

It is optimized for long-term industrial use with minimal signal drift, reducing maintenance requirements and improving system availability. Full compatibility with Bently Nevada 3300 XL monitoring systems ensures seamless integration into existing machinery protection architectures.
