Typical Application Scenarios

Steam Turbine Bearing Monitoring in Power Generation
When turbine pedestals require probe mounting 4 meters from the nearest Proximitor location due to space constraints or thermal zones, the 330130-040-00-05 extends sensing reach while maintaining the ±0.5% linearity required for early fault detection. Pairs with 1.0m probes to create 5.0m total system length for standard Proximitor configurations.

Offshore Platform Gas Compressor Protection
ATEX Zone 1 certification enables direct installation in compressor enclosures where explosive atmospheres may occur during normal operations. The cable's pull strength withstands platform vibration and thermal expansion cycles across 20+ year service intervals without connector degradation.

Refinery Pump Retrofit Projects
When upgrading non-XL 3300 systems to XL specifications on critical process pumps, this cable integrates seamlessly with existing 5mm or 8mm probes during transition periods. Allows incremental migration to XL performance without complete system replacement, minimizing downtime and capital expenditure.

Cement Kiln Drive System Expansion
Extends vibration monitoring coverage to auxiliary drive motors and gearboxes located beyond standard probe cable reach. The 4.0m length bridges typical 2-3 meter gaps between rotating equipment and control panel mounting locations in dusty, high-temperature kiln environments.

Multi-Stage Compressor Train Configuration
Enables distributed Proximitor placement across compressor stages while centralizing monitoring equipment in climate-controlled analyzer houses. Reduces field wiring complexity by positioning Proximitors closer to measurement points, then using standard triad cable for the remaining distance to monitors.

Technical Parameters & Selection Guide

Selection Criteria for System Configuration:

Total system length (probe + extension cable) must match your Proximitor Sensor rating. Common configurations include: 1.0m probe + 4.0m extension = 5.0m Proximitor | 5.0m probe + 4.0m extension = 9.0m Proximitor. Verify Proximitor model number suffix (-50, -90, etc.) before ordering to ensure length compatibility.

For hazardous area installations, confirm that Option 05 (CSA/ATEX/IECEx) meets your specific zone classification requirements. Non-certified Option 00 is available for general industrial use where agency approvals are not mandated.

When mixing XL and non-XL components, system performance defaults to non-XL specifications (±2% linearity vs. ±0.5% for pure XL systems). For critical machinery requiring maximum accuracy, maintain component consistency within the XL family.

Extended Functions

Field Wiring Integration: The Proximitor Sensor output supports 0.2–1.5 mm² (16–24 AWG) 3-conductor shielded triad cable runs up to 305 meters (1,000 feet) to monitoring systems. This two-stage architecture (coaxial probe-to-Proximitor, then triad Proximitor-to-monitor) optimizes signal integrity while minimizing expensive coaxial cable usage.

Connector Protection Options: While standard Option 00 does not include connector protectors, harsh environments benefit from separately-ordered 40180-02 protector pairs (10 per package) or silicone tape 03200006 for temporary installations. Note that silicone tape is incompatible with turbine oil exposure.

System Diagnostics Compatibility: When paired with 3300 XL monitors featuring ADAPT (Automated Diagnostics and Prognostics Technology), the cable's electrical signature enables automated health monitoring—detecting connector degradation, insulation breakdown, or moisture ingress before measurement errors occur.

Modular Expansion Capability: Multiple extension cables can be daisy-chained using 330153-01 connector kits for custom lengths, though each additional connection point introduces minor capacitance and resistance. Consult factory application engineering for configurations exceeding two extension segments.

Frequently Asked Questions

Can this extension cable be used with 5mm proximity probes from the legacy 3300 series?
Yes, the 330130-040-00-05 maintains backward compatibility with both 5mm and 8mm non-XL probes. However, when mixing XL cables with non-XL probes, the overall system performance will conform to non-XL specifications (±2% linearity instead of ±0.5%). For maximum accuracy in critical applications, we recommend maintaining component consistency within either the XL or non-XL family.

What is the maximum total system length I can achieve by combining multiple extension cables?
While the 3300 XL architecture technically supports daisy-chaining extension cables, each additional connector introduces cumulative capacitance and resistance that can affect linearity. Bently Nevada recommends limiting total coaxial cable length (probe + extensions) to 9.0 meters for optimal performance. For longer distances, position the Proximitor Sensor closer to the probe and use standard triad cable (up to 305m) for the Proximitor-to-monitor connection.

Do I need special tools to install the ClickLoc connectors in the field?
No specialized tools are required for standard cable-to-cable or cable-to-Proximitor connections—the ClickLoc design enables finger-tight installation with positive tactile and audible feedback when properly seated. However, if you need to terminate custom field wiring to ClickLoc connectors, the 163356 crimp tool kit is necessary for proper contact installation.

How do I verify that my Proximitor Sensor is rated for the total system length after adding this extension cable?
Check the Proximitor model number suffix: -50 indicates 5.0m total system length, -90 indicates 9.0m, etc. Add your probe length plus extension cable length to determine total system length, then confirm it matches your Proximitor rating. For example, a 330180-50-05 Proximitor (5.0m rating) requires a combined probe + extension length of 5.0m—such as a 1.0m probe with this 4.0m extension cable.

Is this cable suitable for continuous operation in steam turbine bearing housing environments at 150°C?
Yes, the 330130-040-00-05 is rated for continuous operation from 0°C to +177°C, making it appropriate for most turbine bearing applications. The FEP insulation maintains its dielectric properties and mechanical integrity across this temperature range. However, ensure that connector areas remain within specification—if connector exposure exceeds +177°C, consider relocating the connection point or using thermal barriers.

What is the difference between Option 00 and Option 05 in the part number?
Option 05 includes CSA, ATEX, and IECEx hazardous area certifications, enabling installation in Zone 0/1 (ATEX) and Division 1 (CSA) classified locations where explosive atmospheres may be present. Option 00 is the standard industrial version without agency certifications, suitable for general-purpose applications. Both options share identical electrical and mechanical specifications—the difference is purely in certification documentation and markings.
