Introduction
The Bently Nevada 330180-52-00 is a 3300 XL 8mm Proximity Sensor, more precisely a 3300 XL Proximitor Sensor used as the signal-conditioning component within the 3300 XL 8mm Proximity Transducer System.
This configuration is specified for a 5.0-meter (16.4-foot) system length and is supplied without mounting hardware. The final -00 indicates that no agency approval option is required. This makes the 330180-52-00 a practical configuration for installations where the mounting arrangement is already available or where the user prefers to provide the mounting hardware separately.
Working together with a compatible 3300 XL 8mm probe and extension cable, the sensor converts the probe's eddy-current measurement into an electrical output proportional to the distance between the probe tip and the conductive target. The system is designed for both static shaft-position and dynamic vibration measurements, with applications extending to Keyphasor reference and speed measurement.
Technical Specifications
The 330180 series uses a two-part ordering structure. In 330180-52-00, the 52 specifies the 5.0 m system-length configuration without mounting hardware, while 00 indicates that agency approval is not required.

Applications
Turbine Vibration Monitoring
The 330180-52-00 can be used as the signal-conditioning element in suitable turbine monitoring systems. When connected to the appropriate probe, it provides measurement information for shaft movement and rotor vibration.
Compressor Monitoring
High-speed compressors require dependable information about rotor behavior. The 3300 XL 8mm system provides non-contact measurement suitable for compatible compressor and fluid-film bearing applications.
Generator and Motor Monitoring
The Proximitor can process signals from compatible probes installed on generators, motors, and other rotating machines. This supports continuous monitoring of shaft position and dynamic movement.
Fluid-Film Bearing Machines
One of the primary applications of the 3300 XL 8mm system is monitoring machinery with fluid-film bearings. Shaft displacement and vibration measurements can provide important information about rotor operating condition.
Keyphasor and Speed Measurement
The system can also support Keyphasor reference and speed measurement applications when paired with the appropriate probe and monitoring equipment.
Machinery Protection
When integrated with a compatible monitoring platform, the Proximitor provides the conditioned electrical signal required for machinery protection and condition-monitoring functions.
Retrofit Installations
The no-hardware configuration is particularly convenient for retrofit projects where an existing mounting arrangement can be reused. It avoids paying for a mounting configuration that may not match the customer's panel or DIN installation.
Custom Mounting Arrangements
For engineering teams that require a particular physical installation method, the absence of factory-supplied mounting hardware provides additional flexibility.
Advantages
5.0 m System Configuration
The 5.0 m system length is a widely useful configuration for machinery installations where the probe and Proximitor are separated by a moderate cable distance.
No Mounting Hardware
The -52 configuration is specifically supplied without mounting hardware. This can be advantageous when the installation already has suitable brackets, mounting provisions, or an application-specific enclosure.
3300 XL 8mm Platform
The 3300 XL 8mm platform is designed for demanding rotating-machinery applications and provides a mature solution for shaft-position and vibration measurement.
Broad Probe Compatibility
The Proximitor Sensor input is designed to accept compatible 3300-series 5mm, 8mm, or 3300 XL 8mm proximity probes and extension cables, making the sensor useful across several compatible transducer configurations.
Stable Signal Conditioning
The Proximitor converts the probe's eddy-current response into a usable output signal. This provides the interface between the sensing element and downstream monitoring equipment.
Strong RFI/EMI Immunity
The 3300 XL Proximitor design incorporates improved resistance to radio-frequency and electromagnetic interference, helping maintain stable operation in electrically demanding industrial environments.
Compact Housing
With dimensions of approximately 81.3 × 61.2 × 63.5 mm, the sensor provides a relatively compact package for machinery monitoring cabinets and equipment enclosures.
Flexible Installation
Because the 330180-52-00 does not include mounting hardware, users can select a mounting solution appropriate to their cabinet, enclosure, or machinery-monitoring layout.
Proven Industrial Architecture
The complete 3300 XL 8mm system combines a probe, extension cable, and Proximitor Sensor into a calibrated measurement chain, providing a practical solution for continuous rotating-equipment monitoring.
Technical FAQs
1. What is the Bently Nevada 330180-52-00?
It is a 3300 XL Proximitor Sensor configured for a 5.0 m (16.4 ft) system length, supplied without mounting hardware and without an agency-approval option.
2. What does the “52” in 330180-52-00 mean?
The 52 identifies the 5.0-meter system-length configuration with no mounting hardware.
3. What does the final “00” mean?
The 00 indicates that the unit is supplied with no agency approval requirement.
4. Is 330180-52-00 a proximity probe?
No. It is the Proximitor Sensor, not the physical proximity probe. A complete 3300 XL 8mm transducer system normally combines the Proximitor with a compatible probe and extension cable.
5. What probe can be used with this sensor?
The Proximitor Sensor input accepts compatible 3300-series 5mm, 8mm, or 3300 XL 8mm proximity probes and extension cables. The exact probe and cable combination should be selected according to the required system configuration.
6. What is the system length?
The specified system length is 5.0 meters (16.4 feet).
7. Does the 330180-52-00 include mounting hardware?
No. The 52 configuration specifically means no mounting hardware. This distinguishes it from 330180-50-00 panel-mount and 330180-51-00 DIN-mount configurations.
8. What are the approximate dimensions?
The Proximitor Sensor is approximately 81.3 mm × 61.2 mm × 63.5 mm. The actual installation envelope should also account for connector and wiring clearance.
9. How much does the sensor weigh?
The typical Proximitor Sensor weight is approximately 246 g (0.246 kg). This is the sensor weight rather than the complete probe-and-cable system.
10. What is the difference between 330180-50-00, 330180-51-00, and 330180-52-00?
All three are 5.0 m system-length configurations with the same general Proximitor function. The difference is the mounting arrangement:
| Model | System Length | Mounting |
|---|
| 330180-50-00 | 5.0 m | Panel mount |
| 330180-51-00 | 5.0 m | DIN mount |
| 330180-52-00 | 5.0 m | No mounting hardware |
