330130-045-12-05 FluidLoc Cable with Connector Protector

330130-045-12-05 is a high‑performance specialty Bently Nevada 3300 XL series extension cable with a total length of 4.5 meters (14.8 feet). This model integrates three core protection technologies: FluidLoc leak‑resistant technology to prevent oil migration through the cable interior, pre‑installed connector protectors for reliable environmental sealing, and CSA, ATEX, and IECEx hazardous area approvals for safe use in explosive atmospheres. It does not include armor.

It is an essential component of the 3300 XL 8 mm eddy current probe system, designed for applications requiring the precise 4.5 meter length to match a 0.5 meter hazardous area approved probe to form a complete 5 meter intrinsically safe system, along with oil leak prevention and connector environmental sealing without the need for mechanical armor. 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, oil mist, moisture, and intrinsic safety requirements are present. When using a 0.5 meter hazardous area approved probe (e.g., 330101-XX-05-XX-05), a 4.5 meter hazardous area approved extension cable is required to form a complete 5 m IS system (0.5 m + 4.5 m = 5 m). This model meets this precise total length matching requirement while providing internal FluidLoc leak protection, external connector environmental sealing, and hazardous area approvals – a non‑armored IS solution for hazardous areas with oil leakage risk and oil mist/moisture exposure.

This model meets this precise total length matching requirement while providing FluidLoc internal leak prevention, connector protector external environmental sealing, and hazardous area approvals – a non‑armored IS solution for hazardous areas with oil leakage risk and oil mist/moisture exposure.

FluidLoc Leak‑Resistant Technology & Connector Protector Details

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.

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

Connector Protector

This model includes pre‑installed fluorosilicone connector protectors, which provide:

• Environmental Sealing: Prevents turbine oil, moisture, and dust from penetrating the connector interface, reducing the risk of signal degradation or short circuits

• Enhanced Connection Reliability: Forms a sealed sleeve after connector mating, ensuring long‑term connection stability

• Media Ingress Prevention: In oil mist environments, the protector prevents oil from seeping through the connector threads

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

Important Note: 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 plus hazardous area approvals, is the ideal non‑armored choice for preventing both internal oil migration and external environmental ingress in turbine oil environments within hazardous areas.

Comparison with Related Models

Selection Tip: This model is the ideal non‑armored IS solution for hazardous area applications requiring both internal oil leak prevention and external connector environmental sealing. If the installation environment also involves mechanical impact, crushing, or abrasion risks, consider the armored version (e.g., 330130-045-13-05).

Approvals & Conditions of Safe Use

Hazardous Area Certifications

330130-045-12-05 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-05-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

330130-045-12-05 is suitable for the following typical applications:

1. Precise Total Length Matching for 5 m IS Systems (0.5 m Hazardous Area Probe) + Dual Protection: When using a 0.5 meter hazardous area approved probe, a 4.5 meter hazardous area approved extension cable is required to form a complete 5 m IS system (0.5 m + 4.5 m = 5 m). This model meets this precise total length matching requirement while providing FluidLoc internal leak prevention, connector environmental sealing, and hazardous area approvals – ideal for hazardous areas with oil leakage risk and oil mist/moisture exposure.

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, connector protectors prevent oil mist from penetrating the connector interface, and hazardous area approvals ensure safety compliance.

3. Oil Contact + Oil Mist/Moisture Environments in Hazardous Areas: Gearboxes, engine test stands, and similar equipment in classified areas may expose cables to liquid oil and also operate in oil‑mist or humid conditions. Triple protection provides comprehensive security.

4. Hazardous Area Applications Where Armor is Not Required: If the installation environment has no mechanical impact, crushing, or abrasion risks, this model offers leak prevention, environmental sealing, and hazardous area approvals at a smaller diameter and lower cost than armored versions.

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 0.5 m hazardous area approved probe, select this model (4.5 m); if using a 1.0 m hazardous area approved probe, select a 4.0 m FluidLoc+protector hazardous area cable (e.g., 330130-040-12-05).

• System Integrity: All components entering the hazardous area (probe, extension cable, connector protectors) must carry the same hazardous area approval rating. This model includes pre‑installed protectors and hazardous area approvals, meeting system requirements.

• Slightly Larger FluidLoc Cable Diameter: FluidLoc cable outer diameter is 3.94 mm (standard 3.68 mm). The connector protector outer diameter is 12.4 mm. Verify clearance when routing through conduit or tight spaces.

• Bend Radius: Minimum bend radius is 25.4 mm (1.0 in), the same as standard cable.

• Ambient Temperature: If the application environment exceeds +177°C, consider the ETR (Extended Temperature Range) FluidLoc+protector hazardous area cable series (e.g., 330190-045-12-05).

• Armor Requirements: If the installation environment also involves mechanical impact, crushing, or abrasion risks, consider the armored version (e.g., 330130-045-13-05).

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 provides a FluidLoc+protector dual‑protection plus hazardous area approvals option for 5 m IS systems using a 0.5 m probe.

Mechanical Dimensions & Installation

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

• Connector Protector Outer Diameter: 12.4 mm (0.49 in) maximum

• Connector: Features the ClickLoc design. Finger‑tighten until an audible "click" is heard — no special tools are required. The protector automatically forms a seal when 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 in hazardous areas, use a pull rope or fish tape attached to the cable jacket (not the connector protector) to avoid stress. Since this model has no armor, the pull rope must be attached to the cable jacket. If protector removal is required for inspection, refer to the datasheet for tool instructions, and ensure proper reinstallation to maintain seal integrity.
