Introduction
The Bently Nevada 330180-X0-00 145004-82 is a 3300 XL Proximitor Sensor designed for use within 5 mm and 8 mm eddy-current proximity transducer systems. Installed together with a compatible proximity probe and extension cable, it provides the electronic interface required to convert changes in probe-to-shaft distance into a proportional electrical output.
The 3300 XL 8 mm proximity system is intended for direct measurement of shaft position and dynamic shaft vibration. It is particularly valuable on rotating equipment where shaft movement provides important information about machine condition, including turbines, compressors, pumps, motors, generators, and fluid-film-bearing machinery. The system can also be configured for Keyphasor reference and speed measurements.
The 330180-X0-00 configuration is associated with a 5 m system length and panel-mount installation, providing a convenient solution for conventional machinery-monitoring cabinets. The additional identification 145004-82 can be retained as a useful reference when matching an existing installed unit or spare.
For replacement applications, the complete transducer configuration should always be considered. Probe type, extension-cable length, mounting arrangement, system length, target material, and required approvals can all influence final compatibility.
Technical Specifications
The 330180-X0-00 is the Proximitor Sensor portion of the system rather than the physical 8 mm sensing probe. The complete 3300 XL 8 mm system consists of a compatible probe, extension cable, and Proximitor Sensor.

Applications
Turbine Monitoring
The 330180-X0-00 can be integrated into turbine monitoring channels where direct shaft vibration and position measurements are required. Shaft data can provide valuable information during startup, shutdown, load changes, and steady-state operation.
Compressor Condition Monitoring
Centrifugal and process compressors depend on stable rotor behavior. Proximity measurements can help identify changes associated with imbalance, misalignment, rotor movement, and bearing-related conditions.
Pump and Motor Protection
Industrial pumps and motors can benefit from direct shaft-motion measurements in addition to conventional casing vibration. This additional measurement channel can support more complete machinery-condition assessment.
Generator Monitoring
Large generators and other rotating electrical machines can use proximity transducers to observe shaft vibration and position as part of a broader machinery-protection system.
Fluid-Film Bearing Machines
The 3300 XL 8 mm platform is particularly suitable for fluid-film-bearing machines, where direct shaft displacement provides useful information about rotor position and dynamic behavior.
Keyphasor and Speed Measurement
With an appropriate probe arrangement and monitoring system, the proximity transducer can provide a Keyphasor reference or speed-related signal for rotating equipment.
Advantages
Optimized 5-Meter Configuration
The 330180-X0-00 provides a 5 m system arrangement, making it well suited to installations where the Proximitor Sensor can be positioned relatively close to the machine-side sensing location.
Convenient Panel Mounting
The panel-mount configuration integrates naturally into conventional instrumentation cabinets. For maintenance teams replacing an existing panel-mounted Proximitor Sensor, this can help minimize unnecessary changes to the surrounding installation.
Non-Contact Shaft Measurement
The eddy-current principle allows the associated probe to monitor shaft movement without physical contact. This makes the system appropriate for high-speed rotating machinery and continuous measurement.
Broad Probe Compatibility
The 3300 XL Proximitor Sensor input accepts compatible 3300-series 5 mm, 3300 8 mm, and 3300 XL 8 mm proximity probes and extension cables.
Direct Vibration and Position Information
Unlike measurements based only on machine casing movement, proximity sensing observes shaft displacement directly. This makes the technology especially useful for machinery where rotor position and shaft vibration are critical operating parameters.
Stable Industrial Design
The Proximitor Sensor uses an A308 aluminum housing and is designed for industrial instrumentation applications. The published operating temperature range for the Proximitor Sensor extends from -52°C to +100°C, providing useful environmental flexibility.
Interchangeable System Architecture
The 3300 XL 8 mm components are electrically and physically interchangeable with compatible non-XL 3300 5 mm and 8 mm components under the applicable conditions. However, mixing XL and non-XL components limits system performance to the applicable non-XL specifications.
Practical Retrofit Value
For plants already operating 3300-series proximity monitoring channels, a correctly matched 330180-X0-00 can provide a straightforward replacement or maintenance option without requiring an entirely new measurement concept.
Technical FAQs
1. What is the Bently Nevada 330180-X0-00 145004-82?
It is a 3300 XL Proximitor Sensor used with compatible 5 mm or 8 mm proximity probes and extension cables for non-contact shaft vibration and position measurement.
2. What does 145004-82 refer to?
145004-82 is the additional identification supplied with this particular product designation. When replacing an installed unit, it is advisable to compare all markings on the existing Proximitor Sensor rather than relying only on the general 330180-X0-00 model number.
3. Is the 330180-X0-00 the actual 8 mm probe?
No. The 330180-X0-00 is the Proximitor Sensor. The 8 mm proximity probe is a separate field-mounted component positioned near the rotating shaft.
4. What does the X0 configuration indicate?
The X0 configuration corresponds to a 5 m system-length and panel-mount arrangement within the 3300 XL Proximitor Sensor family.
5. What is the linear measurement range?
The published 3300 XL 8 mm system has a linear range of 0.2 to 1.5 mm (8 to 60 mils) under the specified test conditions.
6. What power supply does the Proximitor Sensor require?
The standard configuration requires -17.5 to -26 Vdc without barriers, with maximum consumption of approximately 12 mA. With barriers, the specified supply range differs and should be evaluated according to the applicable installation.
7. How much does the Proximitor Sensor weigh?
The Proximitor Sensor has a typical weight of 246 g (8.67 oz). The complete probe, extension cable, and Proximitor assembly is typically approximately 0.7 kg (1.5 lb).
8. What are the dimensions of the 330180-X0-00?
The relevant published Proximitor mounting dimension is approximately 83.8 mm (3.30 in). Cabinet planning should include additional room for connectors, field wiring, cable routing, and maintenance access.
9. Can this Proximitor Sensor work with an existing 8 mm probe?
Yes. The system accepts compatible 3300 8 mm and 3300 XL 8 mm probes, as well as applicable 5 mm configurations. However, the complete transducer chain should be checked before mixing components.
10. What should be confirmed before ordering a replacement?
Verify the 330180-X0-00 part number, 145004-82 identification, 5 m system length, panel-mount configuration, probe type, extension cable, power requirements, target material, monitoring interface, and certification requirements. For critical machinery, matching the complete system is preferable to selecting a replacement based only on the product family.
