330130-040-11-00 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 two core features: stainless steel armor for superior mechanical protection and FluidLoc leak-resistant technology to prevent oil migration through the cable interior, but does not include connector protectors or hazardous area approvals.
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 probe to form a complete 5 meter system, along with both mechanical protection and oil leak prevention without the need for connector environmental sealing. Typical applications include turbine bearing housings, compressors, and gearboxes where lubricating oil leakage risk and mechanical stress are present.
Model Breakdown: 330130-040-11-00 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 | 040
| 4.0 meters (13.1 ft) | Total cable length for precise system total length matching |
Cable Option | 11
| Armored FluidLoc Cable (No Connector Protector) | Stainless steel armor + FluidLoc leak-resistant construction; no pre-installed connector protector |
Agency Approval | 00
| Not Required | Standard industrial version for non-hazardous areas |
Key Configuration Note: The combination of 040 and 11 is the defining feature of this model. In a 3300 XL system, when using a 1.0 meter probe (e.g., 330101-XX-10-XX), a 4.0 meter extension cable is required to form a complete 5 m system (1.0 m + 4.0 m = 5 m). This model meets this precise total length matching requirement while providing both stainless steel armor and FluidLoc leak-resistant technology, offering dual protection for environments with oil leakage risk and mechanical stress, but without connector protectors for applications where additional connector sealing is unnecessary.
FluidLoc Leak-Resistant Technology & Armor 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.
Synergy with Armor: Armor provides mechanical protection against external physical damage; FluidLoc prevents liquid migration from within. Together, they offer comprehensive protection inside and out.
Stainless Steel Armor
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
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 dry, clean environments where the connector will not contact turbine oil, moisture, or dust
If environmental sealing of the connector is required, consider the 12 (FluidLoc + protector) or 13 (armored FluidLoc + protector) options
Comparison with Related Models
Feature | Standard (00) | Armor Only (01) | FluidLoc Only (10) | This Model (11) | FluidLoc+Protector (12) |
Mechanical Protection (Armor) | No | Yes | No | Yes | No |
Oil Leak Prevention (FluidLoc) | No | No | Yes | Yes | Yes |
Connector Protector | No | No | No | No | Yes |
Typical Applications | Dry, clean | High mechanical stress | Oil leakage risk | High mechanical stress + oil leakage risk | Oil leakage risk + environmental sealing |
Selection Tip: This model is the comprehensive solution for applications requiring both mechanical protection (armor) and oil leak prevention (FluidLoc). It is particularly suitable for turbine bearing housings and similar environments where lubricating oil leakage risk and mechanical stress are present. If connector environmental sealing (e.g., against oil mist or moisture) is also needed, select the 12 or 13 options.
Application Scenarios & Selection Guide
330130-040-11-00 is suitable for the following typical applications:
Precise Total Length Matching for 5 m Systems + Armor + FluidLoc: When using a 1.0 meter probe, a 4.0 meter extension cable is required to form a complete 5 m system (1.0 m + 4.0 m = 5 m). This model meets this precise total length matching requirement while providing both armored mechanical protection and FluidLoc leak prevention — the ideal choice for high-risk areas such as turbine bearing housings.
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 issue, while armor protects the cable from mechanical damage inside the bearing housing.
High Mechanical Stress + Oil Contact Risk: In gearboxes, engine test stands, and similar equipment, cables may be exposed to oil and subjected to vibration and friction. Armor provides mechanical redundancy, while FluidLoc prevents oil migration through the cable interior.
Applications Where Connector Protector is Unnecessary: If the connector is located in a dry, clean 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 probe, select this model (4.0 m); if using a 0.5 m probe, select a 4.5 m armored FluidLoc cable (e.g., 330130-045-11-00).
Slightly Larger FluidLoc Cable Diameter: FluidLoc cable outer diameter is 3.94 mm (standard is 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.
Connector Protection: If the connector may be exposed to oil mist or moisture, select a version with connector protectors (e.g., 330130-040-12-00 or 330130-040-13-00).
Ambient Temperature: If the application environment exceeds +177°C, consider the ETR (Extended Temperature Range) armored FluidLoc cable series (e.g., 330190-040-11-00).
Hazardous Area Requirements: If the installation area has explosive gas atmospheres, select the hazardous area approved version (e.g., 330130-040-11-05).

330130-040-12-00 | 4.0 m | No | Yes | Yes | 1.0 m probe | 5 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.
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 Tips: When routing through conduit, 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.
