330130-045-12-00 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 two core protection technologies: FluidLoc leak‑resistant technology to prevent oil migration through the cable interior, and pre‑installed connector protectors for reliable environmental sealing. It does not include armor or hazardous area approvals.
It is an essential component of the 3300 XL 8 mm eddy current probe system, specifically designed for applications requiring the precise 4.5 meter length to match a 0.5 meter probe to form a complete 5 meter 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 where lubricating oil leakage risk, oil mist, or moisture is present. When using a 0.5 meter probe (e.g., 330101-XX-05-XX), a 4.5 meter extension cable is required to form a complete 5 m system (0.5 m + 4.5 m = 5 m). This model meets this precise total length matching requirement while providing both internal FluidLoc leak protection and external connector environmental sealing.
Model Breakdown: 330130-045-12-00 Configuration Details
Following Bently Nevada’s part number coding system (refer to datasheet Page 19), the fields in this model number represent the following:
Field | Code | Parameter | Description |
Base Model | 330130
| 3300 XL Standard Extension Cable | Compatible with 3300 XL 8 mm and 3300 5 mm series probes |
Length Option | 045
| 4.5 meters (14.8 ft) | Total cable length for precise system total length matching (pairs with 0.5 m probe) |
Cable Option | 12
| FluidLoc Cable with Connector Protector | FluidLoc leak‑resistant construction + pre‑installed connector protector |
Agency Approval | 00
| Not Required | Standard industrial version for non‑hazardous areas |
Key Configuration Note: The combination of 045 and 12 is the defining feature of this model. In a 3300 XL system, when using a 0.5 meter probe, a 4.5 meter extension cable is required to form a complete 5 m system (0.5 m + 4.5 m = 5 m). This model meets this precise total length matching requirement while providing both FluidLoc internal leak prevention and connector protector external environmental sealing – an ideal non‑armored solution for applications 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
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, is the ideal choice for preventing both internal oil migration and external environmental ingress in turbine oil environments.
Comparison with Related Models
Feature | Standard (00) | FluidLoc Only (10) | Protector Only (02) | This Model (12) | Armored FluidLoc+Protector (13) |
Oil Leak Prevention (FluidLoc) | No | Yes | No | Yes | Yes |
Connector Environmental Sealing | No | No | Yes | Yes | Yes |
Mechanical Protection (Armor) | No | No | No | No | Yes |
Typical Applications | Dry, clean | Oil leakage risk | Oil mist, moisture | Oil leakage risk + oil mist/moisture | Oil leakage risk + oil mist/moisture + mechanical stress |
Selection Tip: This model is the ideal non‑armored solution for 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., 330130-045-13-00).
Application Scenarios & Selection Guide
330130-045-12-00 is suitable for the following typical applications:
Precise Total Length Matching for 5 m Systems (0.5 m Probe) + Dual Protection: When using a 0.5 meter probe, a 4.5 meter extension cable is required to form a complete 5 m system (0.5 m + 4.5 m = 5 m). This model meets this precise total length matching requirement while providing FluidLoc internal leak prevention and connector environmental sealing – ideal for applications with oil leakage risk and oil mist/moisture exposure.
Turbomachinery Bearing Housings: Steam turbines, compressors, and gas turbines have lubricating oil circulating inside bearing housings. When the probe passes through the housing wall, if the seal fails, oil may migrate along the cable. FluidLoc cable effectively prevents this, while connector protectors prevent oil mist from penetrating the connector interface.
Oil Contact + Oil Mist/Moisture Environments: In gearboxes, engine test stands, and similar equipment, cables may be exposed to liquid oil and also operate in oil‑mist or humid conditions. Dual protection provides comprehensive security.
Applications Where Armor is Not Required: If the installation environment has no mechanical impact, crushing, or abrasion risks, this model offers leak prevention and environmental sealing at a lower cost and with a smaller diameter 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 probe, select this model (4.5 m); if using a 1.0 m probe, select a 4.0 m FluidLoc+protector cable (e.g., 330130-040-12-00).
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 cable series (e.g., 330190-045-12-00).
Armor Requirements: If the installation environment also involves mechanical impact, crushing, or abrasion risks, consider the armored version (e.g., 330130-045-13-00).
Hazardous Area Requirements: If the installation area has explosive gas atmospheres, select the hazardous area approved version (e.g., 330130-045-12-05).
Comparison with Common Lengths
Model | Length | FluidLoc | Protector | Armor | Typical Matching Probe | System |
330130-040-12-00 | 4.0 m | Yes | Yes | No | 1.0 m probe | 5 m system |
330130-045-12-00 | 4.5 m | Yes | Yes | No | 0.5 m probe | 5 m system |
330130-080-12-00 | 8.0 m | Yes | Yes | No | 1.0 m probe | 9 m system |
330130-085-12-00 | 8.5 m | Yes | Yes | No | 0.5 m probe | 9 m system |
Standard 5 m systems are typically composed of a 1.0 m probe + 4.0 m cable, or a 0.5 m probe + 4.5 m cable. Choose the extension cable length that matches your probe. This model provides a FluidLoc+protector dual‑protection option for 5 m 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 Tips: When routing through conduit, 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.
