The Bently Nevada 330180-51-00 is a 3300 XL 8 mm Proximitor Sensor designed for use in proximity transducer systems. This sensor is a critical component for monitoring fluid-film bearing machines, compression systems, and for providing Keyphasor reference and speed measurements. It provides an output voltage proportional to the distance between the probe tip and a conductive surface, enabling the measurement of both static (position) and dynamic (vibration) parameters. The 3300 XL system is fully compliant with API 670 standards for mechanical configuration, linear range, and temperature stability.
Features
Compatible with 3300 and 3300 XL 5 mm and 8 mm probes.
Supports complete interchangeability of probes, extension cables, and sensors without the need for bench calibration.
Designed for high-density DIN-rail mounting or traditional panel mounting.
Integrated mounting base provides electrical isolation, eliminating the need for separate isolator plates.
Backwards compatible with legacy 3300 series transducer system components.
Applications
Radial vibration and axial (thrust) position monitoring for fluid-film bearing machines.
Monitoring of centrifugal air and process gas compressors.
Rotational speed and phase reference signals via Keyphasor.
High-density machinery protection system installations.

Installation Guidelines
Use 3-conductor shielded triad cable (16 to 24 AWG) for connections between the sensor and the monitor.
The maximum allowable field wiring length between the Proximitor sensor and the monitor is 305 meters (1,000 feet).
The sensor utilizes SpringLoc terminal strips; press the spring mechanism to insert wires securely without the need for a screwdriver.
Ensure the mounting base is properly secured to the DIN rail or panel to maintain electrical isolation.
Always power down the system before inserting or removing modules to prevent electrical damage.
FAQ
What is the 330180-51-00?
It is a 3300 XL 5/8 mm Proximitor Sensor used in proximity transducer systems to measure static (position) and dynamic (vibration) readings, primarily on fluid-film bearing machines.
How does the sensor work?
The system produces a voltage output that is directly proportional to the distance between the probe tip and the observed conductive surface of the machine shaft.
Is it compatible with other components?
Yes, the 3300 XL Proximitor Sensor is fully backward-compatible and interchangeable with other non-XL 3300 series 5 mm and 8 mm probes and extension cables.
