330130-040-11-05 Armored FluidLoc Extension Cable

330130-040-11-05 is a high‑performance specialty Bently Nevada 3300 XL series extension cable with a total length of 4.0 meters (13.1 feet). This model integrates three core features: stainless steel armor for superior mechanical protection, FluidLoc leak‑resistant technology to prevent oil migration through the cable interior, and CSA, ATEX, and IECEx hazardous area approvals for safe use in explosive atmospheres. It does not include connector protectors.

It is an essential component of the 3300 XL 8 mm eddy current probe system, designed for applications requiring the precise 4.0 meter length to match a 1.0 meter hazardous area approved probe to form a complete 5 meter intrinsically safe system, along with mechanical protection, oil leak prevention, and intrinsic safety without the need for connector environmental sealing. Typical applications include turbine bearing housings, compressors, and gearboxes in Zone 0 and Zone 1 hazardous areas such as refineries, petrochemical plants, and natural gas facilities, where lubricating oil leakage risk, mechanical stress, and intrinsic safety are all present.

Model Breakdown: 330130-040-11-05 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 040, 11, and 05 is the defining feature of this model. In a 3300 XL intrinsically safe system, when using a 1.0 meter hazardous area approved probe (e.g., 330101-XX-10-XX-05), a 4.0 meter hazardous area approved extension cable is required to form a complete 5 m IS system (1.0 m + 4.0 m = 5 m). This model meets this precise total length matching requirement while providing stainless steel armor, FluidLoc leak prevention, and hazardous area approvals – triple protection for environments with oil leakage risk and mechanical stress in hazardous areas, but without connector protectors for applications where additional connector sealing is unnecessary.

Triple Protection Details: Armor + FluidLoc + Hazardous Area Approvals

1. Stainless Steel Armor — Mechanical Protection

The armor layer consists of flexible AISI 302 or 304 stainless steel braid, covered with an FEP outer jacket, providing the following protection:

• Crush Resistance: Prevents cable damage from compression during installation or operation

• Tensile Strength: Enhances overall cable pull strength for conduit routing

• Abrasion Resistance: Prevents insulation damage from friction against metal conduits or equipment edges

• Cut Resistance: Protects internal conductors from accidental cuts or sharp object damage

In hazardous area environments, the armor not only provides mechanical protection but also serves as an additional safety barrier against external impact that could compromise cable integrity, thereby maintaining intrinsic safety system integrity.

2. FluidLoc Leak‑Resistant Technology

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.

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

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

• Synergy with Armor: Armor provides external mechanical protection; FluidLoc prevents internal liquid migration. Together, they offer comprehensive protection inside and out.

3. Hazardous Area Approvals — Intrinsic Safety

This model carries ATEX, IECEx, and CSA intrinsically safe approvals for use in Zone 0, Zone 1, and Zone 2 hazardous areas, ensuring safe operation in explosive gas atmospheres.

No Connector Protector on This Model

This model does not include pre‑installed connector protectors, meaning:

• The connector is exposed to the environment without additional oil or dust sealing

• Suitable for applications where the connector is located in a dry, clean junction box without exposure to turbine oil, moisture, or dust

• If environmental sealing of the connector is required, consider the 12-05 (FluidLoc + protector + approvals) or 13-05 (armored FluidLoc + protector + approvals) options

Comparison with Related Models

Selection Tip: This model is the comprehensive solution for hazardous area applications requiring both mechanical protection (armor) and oil leak prevention (FluidLoc). It is particularly suitable for turbine bearing housings in classified areas where lubricating oil leakage risk, mechanical stress, and intrinsic safety are all present. If connector environmental sealing (e.g., against oil mist or moisture) is also needed, select the 12-05 or 13-05 options.

Approvals & Conditions of Safe Use

Hazardous Area Certifications

330130-040-11-05 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-10-XX-05) and Proximitor Sensors (e.g., 330180-50-05) to maintain a complete intrinsically safe system. Mixing with non‑approved components will void the hazardous area certification.

Application Scenarios & Selection Guide

330130-040-11-05 is suitable for the following typical applications:

1. Precise Total Length Matching for 5 m IS Systems + Armor + FluidLoc + Approvals: When using a 1.0 meter hazardous area approved probe, a 4.0 meter hazardous area approved extension cable is required to form a complete 5 m IS system (1.0 m + 4.0 m = 5 m). This model meets this precise total length matching requirement while providing armor, FluidLoc, and hazardous area approvals – the ideal choice for high‑risk areas such as turbine bearing housings in hazardous locations.

2. 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 are often located in Zone 1 or Zone 2 areas. FluidLoc cable prevents oil migration, armor protects against mechanical damage, and hazardous area approvals ensure safety compliance.

3. High Mechanical Stress + Oil Contact Risk in Hazardous Areas: Gearboxes, engine test stands, and similar equipment in classified areas may expose cables to oil and strong vibration/friction. Armor provides mechanical redundancy, FluidLoc prevents internal oil migration, and hazardous area approvals guarantee safe operation.

4. Hazardous Area Applications Where Connector Protector is Unnecessary: If the connector is located in a dry, clean intrinsically safe junction box without exposure to oil mist or moisture, this model meets requirements at a lower cost than versions with protectors.

Selection Notes:

• Total Length Matching: Probe length + extension cable length = Proximitor Sensor total system length (5 m or 9 m). Verify your probe length: if using a 1.0 m hazardous area approved probe, select this model (4.0 m); if using a 0.5 m hazardous area approved probe, select a 4.5 m armored FluidLoc hazardous area cable (e.g., 330130-045-11-05).

• System Integrity: All components entering the hazardous area (probe, extension cable, connector protectors) must carry the same hazardous area approval rating. This model does not include connector protectors – if needed, select a version with protectors.

• Slightly Larger FluidLoc Cable Diameter: FluidLoc cable outer diameter is 3.94 mm (standard 3.68 mm); armored section diameter is 7.67 mm. Verify clearance when routing through conduit or tight spaces.

• Bend Radius: The minimum bend radius for armored cable remains 25.4 mm (1.0 in), but armor increases stiffness. Allow adequate clearance.

• Weight: Armored FluidLoc cable weighs approximately 103 g/m. Consider tensile load on connectors and probes during installation.

• Ambient Temperature: If the application environment exceeds +177°C, consider the ETR (Extended Temperature Range) armored FluidLoc hazardous area cable series (e.g., 330190-040-11-05).

• Connector Sealing: If the connector may be exposed to oil mist or moisture, select a version with connector protectors (e.g., 330130-040-12-05 or 330130-040-13-05).

Comparison with Common Lengths

Standard 5 m intrinsically safe systems are typically composed of a 1.0 m hazardous area probe + 4.0 m hazardous area cable, or a 0.5 m hazardous area probe + 4.5 m hazardous area cable. Choose the extension cable length that matches your probe. This model represents the ideal configuration for hazardous areas requiring both mechanical impact resistance and oil leak prevention.

Mechanical Dimensions & Installation

• Cable Outer Diameter:

  • Armored section: 7.67 mm (0.302 in) maximum

  • Armor ferrule: 10.2 mm (0.40 in) maximum

  • Non‑armored section (near connector end): FluidLoc cable 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.

• 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 in hazardous areas, use a pull rope or fish tape attached to the cable jacket (not the connector) to avoid stress. Since this model does not include connector protectors, take care to protect the connector from scratches during conduit routing. If conduit protection is needed, select a version with protectors or field‑install protectors suitable for hazardous area use.
