Applications
The 330130-075-00-05 is designed for the signal connection portion of a 3300 XL proximity measurement system. It is particularly valuable in installations where the physical distance between the probe and Proximitor Sensor requires an extended cable run.
Turbine and Generator Monitoring
The cable can be incorporated into proximity measurement arrangements used to monitor shaft vibration, radial position, axial position, and other critical operating conditions on turbines and generators.
Compressor Systems
Large compressors often require monitoring equipment to be positioned away from the actual measurement point. The 7.5-meter length provides useful installation flexibility while retaining the intended 3300 XL system configuration.
Pumps and Motors
For industrial pumps, motors, and other rotating equipment, proximity measurement systems can provide valuable information about shaft movement and machine condition. The 330130-075-00-05 provides the necessary extension between compatible system components.
Fluid-Film Bearing Machinery
The 3300 XL 8 mm system is commonly associated with machinery using fluid-film bearings. In these applications, proximity measurements can be used for vibration and shaft-position monitoring.
Keyphasor and Speed Measurement
Compatible proximity measurement arrangements can also support Keyphasor reference and speed measurements. Correct cable selection helps maintain the required electrical relationship between the probe, extension cable, and Proximitor Sensor.
Hazardous-Area Installations
The CSA, ATEX, and IECEx approval configuration makes this model attractive for installations where equipment certification requirements must be considered. The complete system installation must still satisfy the applicable hazardous-area requirements.
Advantages
Purpose-Built 7.5 m Configuration
The 7.5-meter length strikes a useful balance between installation reach and cable management. It can provide additional distance without resorting to an unnecessarily long cable that may complicate routing.
Standard 75Ω Triaxial Construction
The 75Ω triaxial design is engineered for the electrical requirements of the 3300 XL proximity system. Controlled capacitance and resistance characteristics help support predictable signal behavior within the complete transducer system.
FEP Insulation
FEP insulation provides a durable electrical insulation system suitable for demanding industrial environments. It is a practical material choice for machinery monitoring cables exposed to challenging operating conditions.
Standard Cable Protector Design
The -00 configuration uses standard cable protectors, providing a straightforward installation option for applications that do not require the armored or FluidLoc configurations available on other 3300 XL extension cable variants.
Multi-Agency Approval
The -05 approval option is associated with CSA, ATEX, and IECEx approvals. This gives engineers greater flexibility when specifying the cable for installations subject to different regional or hazardous-area certification requirements.
Secure Gold-Plated Connectors
Gold-plated brass or gold-plated beryllium copper connector materials provide a reliable contact surface and support long-term connection performance in industrial instrumentation applications.
Designed for System Interchangeability
The 3300 XL proximity system is designed around interchangeable probes, extension cables, and Proximitor Sensors within the appropriate system configuration. This can simplify maintenance and replacement planning compared with systems requiring individual component matching or bench calibration.
Technical FAQs
1. What is the Bently Nevada 330130-075-00-05?
It is a 3300 XL Standard Extension Cable designed for the Bently Nevada 3300 XL 8 mm proximity transducer system. The cable connects a compatible proximity probe with its associated Proximitor Sensor.
2. How long is the 330130-075-00-05?
The cable length is 7.5 meters, or approximately 24.6 feet.
3. What does “075” mean in the part number?
The 075 designation identifies the 7.5-meter cable-length option.
4. What does “00” represent?
The 00 designation identifies the standard cable protector and cable configuration. It distinguishes this version from armored, FluidLoc, or other specialized configurations.
5. What does the “05” option specify?
The 05 designation identifies the applicable agency approval configuration, associated with CSA, ATEX, and IECEx approvals.
6. What type of insulation is used?
The standard cable uses FEP, or fluoroethylene propylene, insulation around the 75Ω triaxial cable construction.
7. What is the minimum bend radius?
The specified minimum bend radius is 25.4 mm, or 1 inch. Installation should avoid tighter bends to reduce mechanical stress on the cable.
8. Can this cable be used with a 3300 XL 8 mm proximity probe?
Yes, it is intended for use as part of a compatible 3300 XL 8 mm proximity transducer system. The complete probe, extension cable, and Proximitor Sensor configuration should be verified before installation.
9. Does the 330130-075-00-05 require individual system calibration?
The 3300 XL system is designed to support interchangeability of compatible probes, extension cables, and Proximitor Sensors, reducing the need to individually match or bench-calibrate these components. The exact installation should nevertheless follow the applicable system documentation and configuration requirements.
