Bently Nevada 330104‑00‑07‑50‑02‑05 Detailed Product Overview
Brand Information
This product is part of the Bently Nevada condition monitoring product family, a widely used suite of monitoring devices in industrial environments. The brand is known for delivering robust, reliable, and long‑lasting vibration and displacement measurement solutions for critical machinery.
Product Series
330104‑00‑07‑50‑02‑05 belongs to the 3300 XL 8 mm Proximity Transducer System Series. This series is a proven platform for eddy current based non‑contact measurement of shaft vibration and position. It is widely applied across rotating equipment protection and condition monitoring systems.
Product Description
The 330104‑00‑07‑50‑02‑05 is an 8 mm proximity probe designed to measure shaft vibration and radial displacement in rotating machinery. It operates using eddy current sensing technology: a magnetic field is generated at the probe tip and changes in the field caused by proximity of a conductive surface are converted to an electrical signal.
The suffix “50” denotes a medium‑length cable configuration, while “02‑05” represents specific cable and connector specifications tailored for industrial installation needs. This model combines precise measurement capability with a durable construction to ensure reliable performance even in harsh conditions such as high temperatures, oil contamination, and mechanical vibration.
The probe is typically installed with an extension cable and signal conditioning module to form a complete transducer system used in continuous monitoring.

Applications
This proximity probe is used wherever continuous vibration and shaft position measurement is critical for safe and efficient machinery operation. Typical application areas include:
- Steam turbines and gas turbines
- Centrifugal and reciprocating compressors
- Industrial pumps driven by electric motors or engines
- Large electric motors and generators
- Gearboxes and mechanical drive trains
- Fans and blowers in process plants
The medium‑length cable configuration makes this model especially suited for installations where the monitoring rack is at a moderate distance from the machine sensors.
Product Advantages
Non‑Contact Measurement
The eddy current principle allows measurement without physical contact, reducing wear and ensuring long service life.
Medium Cable Length Flexibility
The 2 m system length provides installation flexibility in systems where proximity sensors are not close to the monitoring electronics.
Robust Industrial Design
Stainless steel housing, sealed construction, and resistance to environmental stresses make it suitable for challenging industrial environments.
High Measurement Accuracy
Provides repeatable and accurate vibration and displacement data, essential for condition‑based maintenance strategies.
Wide Compatibility
Designed to be fully compatible with 3300 XL series monitoring systems, allowing straightforward integration with existing plant systems.
