Introduction
The Bently Nevada 330180-X1-05 143416-84 is a 3300 XL Proximitor Sensor intended for precision, non-contact measurement of shaft vibration and position. Used together with a compatible proximity probe and extension cable, it forms an eddy-current transducer system capable of converting changes in probe-to-shaft distance into a proportional voltage signal.
The X1 configuration is designed for DIN-rail mounting, making this version especially useful in compact instrumentation cabinets where convenient rail installation and efficient panel organization are important. The -05 option is associated with CSA, ATEX, and IECEx approvals, supporting appropriately engineered installations in hazardous environments.
The additional identification 143416-84 should be retained when specifying this particular unit. For replacement applications, it is good practice to match the complete Proximitor identification together with the existing probe, extension cable, system length, mounting arrangement, and approval requirements.
Technical Specifications
The 3300 XL Proximitor Sensor is the electronic signal-conditioning component rather than the physical probe itself. It accepts a compatible 3300-series 5 mm or 8 mm proximity probe and extension cable and provides the output required by the associated machinery-monitoring system.

Applications
Turbine Vibration Monitoring
The sensor can be used with suitable 8 mm proximity probes to monitor shaft vibration and position on steam and gas turbines. Direct rotor measurement is valuable for observing machine behavior during startup, shutdown, and normal operation.
Compressor Protection
Centrifugal and process compressors can benefit from direct shaft measurements when monitoring rotor dynamics, bearing behavior, and changes in machine operating condition.
Pump and Motor Monitoring
For industrial pumps and motors, proximity measurements can complement conventional vibration sensors by providing direct information about shaft movement.
Generator Monitoring
The 3300 XL proximity architecture is suitable for generator and other large rotating-machine applications where shaft vibration and position are important protection parameters.
Fluid-Film Bearing Machines
The non-contact eddy-current measurement principle is particularly useful on fluid-film-bearing machines, where direct observation of shaft movement can provide more meaningful rotor information than casing vibration alone.
Keyphasor and Speed Measurement
With the correct probe arrangement and monitoring channel, the system can also be used for rotational reference and speed-related measurements. The 3300 XL platform identifies Keyphasor and speed measurement among its principal applications.
Advantages
DIN-Rail Installation
The X1 configuration provides a DIN-rail mounting arrangement, which can simplify cabinet installation and make efficient use of limited instrumentation-panel space.
9-Meter System Configuration
The 9 m total system length provides useful installation flexibility for machinery where the probe and monitoring cabinet are separated by a considerable distance. The configuration is commonly specified as a 9 m system within the 3300 XL Proximitor family.
Multi-Agency Approval
The -05 option is associated with CSA, ATEX, and IECEx approvals, making this configuration attractive for appropriately designed hazardous-area machinery-monitoring systems.
Non-Contact Operation
Eddy-current sensing measures the target without physical contact. This eliminates mechanical wear between the sensing element and rotating shaft and makes the technology suitable for continuous monitoring.
Direct Shaft Measurement
The system provides direct shaft displacement information, supporting both static position and dynamic vibration measurements. This is particularly valuable on machines where rotor behavior is a key indicator of operating condition.
Wide 3300-Series Compatibility
The Proximitor accepts compatible 3300-series 5 mm or 8 mm proximity probes and extension cables, allowing it to fit into a broad range of established machinery-monitoring configurations.
High-Frequency Response
With a frequency response extending to approximately 10 kHz, the system provides useful bandwidth for demanding rotating-equipment monitoring applications.
Rugged Industrial Construction
The A308 aluminum housing and wide operating-temperature range of approximately -52°C to +100°C make the Proximitor suitable for demanding industrial environments.
Established 3300 XL Architecture
The modular probe, extension cable, and Proximitor arrangement provides a practical approach to installation, maintenance, and replacement. When the complete configuration is matched correctly, it can be integrated into established machinery-monitoring systems without changing the fundamental measurement principle.
