330130-080-12-05 FluidLoc Cable with Connector Protector

330130-080-12-05 is a high-performance Bently Nevada 3300 XL series extension cable with a total length of 8.0 meters (26.2 feet). This model integrates two core features: FluidLoc leak-resistant cable (with pre-installed connector protectors) to prevent oil migration through the cable interior, and CSA, ATEX, and IECEx hazardous area approvals for safe use in explosive atmospheres.

It is an essential component of the 3300 XL 8 mm eddy current probe system, specifically designed for demanding industrial environments where both oil leakage risk and explosive gas atmospheres exist, such as bearing housing monitoring on turbomachinery, compressors, and pumps in refineries, petrochemical plants, and natural gas facilities.

Model Breakdown: 330130-080-12-05 Configuration Details

Following Bently Nevada’s part number coding system (refer to datasheet Page 19), the fields in this model number represent the following:

Key Configuration Note: The combination of 12 and 05 is the defining feature of this model. It offers both FluidLoc leak protection and hazardous area certification, making it the ideal solution for turbine bearing housings and similar applications where both oil contact and explosive atmospheres are present.

FluidLoc Leak-Resistant Technology Explained

What is FluidLoc?

FluidLoc is a patented technology from Bently Nevada that incorporates a specialized sealing structure inside the cable to prevent oil or other liquids from migrating through the gap between the center conductor and outer conductor via capillary action. In standard cables, if the probe tip seal fails or the cable jacket is damaged, oil can continuously migrate through the cable interior and eventually leak out at the connector or Proximitor Sensor end, causing environmental contamination or equipment damage.

How FluidLoc Works

• Blocks Migration Paths: The FluidLoc structure fills the voids between conductors along the entire cable length, eliminating pathways for liquid capillary migration.

• Dual Sealing: When combined with connector protectors, it provides an additional sealing barrier at the connector interface.

• Compatible Media: Turbine oil, lubricating oil, water, and most industrial fluids.

Comparison with Standard Cable

Important Note: FluidLoc cable does not replace the pressure seal at the probe tip. However, if the probe tip seal fails, FluidLoc can prevent further oil migration along the cable to the outside. This additional protection is especially critical in hazardous areas.

Approvals & Conditions of Safe Use

Hazardous Area Certifications

330130-080-12-05 carries the following hazardous area approvals, suitable for installations in major industrial regions worldwide:

Conditions of Safe Use (Intrinsically Safe Systems)

When used in an intrinsically safe system, the following conditions must be observed:

• Barriers/Isolators: Must be installed with intrinsically safe zener barriers per Bently Nevada drawing 141092, or with galvanic isolators.

• Entity Parameters (when connected to approved Proximitor Sensor):

  • Ui = -28V

  • Ii = 140 mA

  • Pi = 0.91 W

  • Ci = 47 nF

  • Li = 1460 μH

• Installation Environment: The Proximitor Sensor must be installed in a non-hazardous area or within an approved explosion-proof enclosure.

Important: This cable must be used with hazardous area approved probes (e.g., 330101-XX-XX-XX-05) and Proximitor Sensors (e.g., 330180-XX-05) to maintain a complete intrinsically safe system. Mixing with non-approved components will void the hazardous area certification.

Connector Protector

This model includes pre-installed connector protectors (fluorosilicone material), which provide:

• Environmental Sealing: Prevents oil, moisture, and dust from penetrating the connector interface

• Enhanced Leak Protection: Works together with the FluidLoc cable to create a complete leak-proof path from probe to connector

• Intrinsic Safety Integrity: In hazardous areas, connector protectors help maintain sealing at the connection point, preventing media ingress that could affect intrinsic safety performance

The datasheet specifically notes that silicone tape is not recommended for applications where the probe-to-extension cable connection will be exposed to turbine oil, and connector protectors are the recommended alternative. This model, with both FluidLoc and protectors, is the ideal choice for hazardous area installations in turbine oil environments.

Application Scenarios & Selection Guide

330130-080-12-05 is suitable for the following typical applications:

1. Turbomachinery Bearing Housings in Hazardous Areas: Steam turbines, compressors, and gas turbines in refineries and petrochemical plants have lubricating oil circulating inside bearing housings, and the equipment is often located in Zone 1 or Zone 2 areas. FluidLoc cable prevents oil migration, while hazardous area approvals ensure safety compliance.

2. Offshore Platform Turbine Equipment: Gas generators and compressors in marine environments have extremely high requirements for both leak prevention and explosion protection. This model provides dual assurance.

3. Hazardous Areas with Oil Mist or Liquid Oil Contact: Gearboxes, engine test stands, and similar equipment in chemical plants where cables may be exposed to oil mist or splashed oil, and the area requires hazardous area certification.

4. Long-Distance 9 m Monitoring Systems in Hazardous Areas: When paired with a 1.0 m hazardous area approved probe, this cable completes a 9 m intrinsically safe monitoring chain while ensuring full-path leak protection.

Selection Notes:

• Total Length Matching: Probe length + extension cable length = Proximitor Sensor total system length (5 m or 9 m). Verify that both the probe and Proximitor Sensor are approved versions and that total lengths match.

• Slightly Larger Cable Diameter: FluidLoc cable outer diameter is 3.94 mm (standard is 3.68 mm). When routing through conduit or tight passages, confirm adequate clearance.

• System Integrity: All components entering the hazardous area (probe, extension cable, connector protectors) must carry the same hazardous area approval rating.

• Cost Consideration: The FluidLoc + hazardous area combination has a higher cost, but for turbomachinery applications in hazardous areas, the environmental, safety, and compliance value far exceeds the cost difference.

• Ambient Temperature: If the application environment exceeds +177°C, consider the ETR (Extended Temperature Range) FluidLoc hazardous area cable series (e.g., 330190-080-12-05).

Mechanical Dimensions & Installation

• Cable Outer Diameter: 3.94 mm (0.155 in) maximum

• Connector: Features the ClickLoc design. Finger-tighten until an audible "click" is heard — no special tools are required.

• Connector Protector: Pre-installed, automatically forms a seal when the connector is tightened.

• Installation Drawing: Intrinsically safe system installation must strictly follow Bently Nevada drawing 141092, including barrier selection, grounding, and wiring practices.

• Installation Tips: When routing through conduit, use a pull rope or fish tape attached to the cable jacket (not the connector protector) to avoid stress. After installation, inspect the connector area for any visible oil seepage.
