Introduction
The Bently Nevada 330180-X0-00 145004-99 is a 3300 XL Proximitor Sensor intended for use with compatible 5 mm and 8 mm proximity probes. As the electronic component of an eddy-current proximity transducer system, it converts changes in the distance between the probe tip and a conductive machine shaft into a proportional electrical output.
The 3300 XL 8 mm system is engineered for direct shaft vibration and position measurement, making it particularly valuable on fluid-film-bearing machinery. Typical applications include steam and gas turbines, centrifugal compressors, pumps, motors, generators, and other critical rotating equipment. The same transducer architecture can also support Keyphasor reference and speed measurements when configured appropriately.
The 330180-X0-00 configuration is associated with a 5-meter system length and panel-mount installation. Its traditional panel-mount footprint makes it a practical replacement choice for existing machinery-monitoring cabinets, especially where maintaining the established installation arrangement is a priority.
The additional identification 145004-99 is retained as part of this product designation. When replacing an installed Proximitor Sensor, it is good engineering practice to verify the complete part marking, system length, probe type, extension cable, mounting arrangement, and required approvals before installation.
Technical Specifications
The 330180-X0-00 is the Proximitor Sensor component, rather than the physical 8 mm probe. A complete 3300 XL 8 mm proximity system consists of a compatible probe, extension cable, and Proximitor Sensor.

Applications
Turbine Shaft Vibration
The 330180-X0-00 can be used as part of a turbine shaft-monitoring channel where direct measurement of rotor vibration and position is required. This provides useful information during startup, normal operation, load changes, and shutdown.
Compressor Monitoring
Large compressors depend on controlled rotor dynamics. Proximity measurements can help monitor shaft movement associated with imbalance, misalignment, bearing conditions, and changing operating behavior.
Pump and Motor Condition Monitoring
For industrial pumps and motors, direct shaft measurements can complement conventional casing-vibration instrumentation and provide a more complete picture of mechanical performance.
Generator Monitoring
Generators and other rotating electrical machines can use proximity transducers to monitor shaft movement and vibration as part of a machinery-protection or predictive-maintenance system.
Fluid-Film Bearing Machinery
The 3300 XL 8 mm system is particularly useful on fluid-film-bearing machines because direct shaft displacement can provide valuable information about rotor position and dynamic behavior.
Keyphasor and Speed Measurement
When paired with the appropriate probe and monitoring equipment, the proximity system can provide a Keyphasor reference or speed signal for rotating machinery.
Advantages
5-Meter Panel-Mount Design
The 330180-X0-00 offers a 5-meter system configuration with panel mounting, making it well suited to installations where the Proximitor Sensor can be positioned within a relatively short distance of the machine-side transducer.
Direct Non-Contact Measurement
The eddy-current sensing principle allows the associated probe to monitor shaft movement without contacting the rotating surface. This makes the technology particularly appropriate for high-speed and continuously operating machinery.
Flexible 5 mm and 8 mm Compatibility
The Proximitor Sensor accepts compatible 3300 5 mm, 3300 8 mm, and 3300 XL 8 mm proximity probes and extension cables. This provides useful flexibility when maintaining established 3300-series monitoring systems.
Compact Cabinet Integration
The 3300 XL Proximitor Sensor can be installed in a traditional panel-mount configuration and uses a mounting approach compatible with the established 3300 installation footprint.
Strong Measurement Capability
The system provides both static shaft-position and dynamic shaft-vibration information. This makes one proximity measurement architecture useful for machinery monitoring, protection, trending, and diagnostic applications.
Industrial Construction
The Proximitor Sensor uses an A308 aluminum housing, providing a durable enclosure for industrial instrumentation environments.
Established 3300 XL Platform
The 3300 XL system uses a modular probe, extension cable, and Proximitor Sensor arrangement. This architecture is convenient for maintenance teams because individual components can be inspected and replaced while retaining the broader monitoring design when compatibility is maintained.
Efficient Replacement Option
For facilities already operating compatible 3300-series proximity channels, the 330180-X0-00 can be an attractive replacement candidate when the existing system specifications match. Its familiar panel-mount arrangement can help reduce unnecessary cabinet modifications.
Technical FAQs
1. What is the Bently Nevada 330180-X0-00 145004-99?
It is a 3300 XL Proximitor Sensor designed to operate with compatible 5 mm and 8 mm proximity probes for non-contact measurement of shaft vibration and position.
2. What does 145004-99 mean?
145004-99 is the additional identification supplied with this particular product designation. For replacement purposes, the complete identification on the installed unit should be checked rather than relying solely on the base 330180-X0-00 model number.
3. Is this the actual 8 mm proximity probe?
No. The 330180-X0-00 is the Proximitor Sensor. The 8 mm proximity probe is a separate component installed close to the monitored shaft.
4. What does the X0 configuration indicate?
The X0 configuration corresponds to a 5-meter system length with panel mounting within the 3300 XL Proximitor Sensor configuration family.

The published 3300 XL 8 mm system has a linear range of approximately 0.2 to 1.5 mm (8 to 60 mils) under specified test conditions.
6. What power supply is required?
The standard configuration requires -17.5 to -26 Vdc without barriers, with maximum consumption of approximately 12 mA.
7. How much does the Proximitor Sensor weigh?
The Proximitor Sensor weighs approximately 246 g (8.67 oz). The typical complete transducer system has a total mass of approximately 0.7 kg (1.5 lb).
8. What are the dimensions of the sensor?
The published mechanical information gives approximately 83.8 mm (3.30 in) for the relevant Proximitor mounting dimension. Installation space should also account for connectors, wiring, cable bend radius, and service clearance.

Yes. The 3300 XL Proximitor Sensor accepts compatible 3300 8 mm and 3300 XL 8 mm probes, as well as applicable 5 mm configurations.
10. What should be verified before purchasing a replacement?
Confirm the 330180-X0-00 model, 145004-99 identification, 5 m system length, panel-mount configuration, probe model, extension cable, power requirements, target material, monitoring-system interface, and certification requirements. Matching the complete transducer configuration is the safest approach for critical machinery.
