330130-080-03-05 Armored Cable with Connector Protector

330130-080-03-05 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 three core features: stainless steel armor for superior mechanical protection, pre-installed connector protectors for environmental sealing, 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 that require both mechanical robustness and intrinsic safety. Typical applications include petrochemical plants, natural gas facilities, refineries, and other locations with flammable gases or vapors in Zone 0 and Zone 1 hazardous areas, as well as installations where resistance to mechanical wear, crushing, and pulling stress is required.

Model Breakdown: 330130-080-03-05 Configuration Details

Following Bently Nevada’s part number coding system, the fields in this model number represent the following:

Key Configuration Note: The combination of 03 and 05 is the defining feature of this model. It offers both the mechanical strength of armor and the safety of hazardous area certifications, making it the preferred solution for long-distance routing in hazardous areas with high mechanical stress.

Approvals & Conditions of Safe Use

Hazardous Area Certifications

330130-080-03-05 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.

Armor & Connector Protector Details

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 long-distance 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.

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 integrity

• 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 connector protectors on this model are factory-installed and require no on-site assembly. For hazardous area installations, it is recommended not to remove the connector protectors to maintain certification integrity.

Application Scenarios & Selection Guide

330130-080-03-05 is suitable for the following typical applications:

1. Long-Distance Conduit Routing in Hazardous Areas: In refineries, chemical plants, and natural gas facilities (Zone 0, Zone 1), when cables must be routed through metal conduits or cable trays, the armor protects against damage from sharp edges at conduit ends, while hazardous area approvals ensure system compliance.

2. High Mechanical Stress Combined with Explosion Protection: Near large turbomachinery, compressors, and generators, cables may be subjected to vibration, friction, or accidental impact — armor provides an extra margin of safety, while hazardous area approvals ensure safe operation in explosive atmospheres.

3. Hazardous Area Applications with Turbine Oil Exposure Risk: In turbine bearing housings or compressor lube oil systems, the probe-to-extension cable connection may be exposed to oil mist or liquid oil. Connector protectors prevent oil migration along the cable interior, while hazardous area approvals ensure safety in oil-mist environments.

4. Long-Distance 9 m Monitoring Systems in Hazardous Areas: When paired with a 1.0 m hazardous area approved probe (e.g., 330101-XX-10-XX-05), this cable completes a 9 m intrinsically safe monitoring chain while ensuring mechanical reliability during long-distance routing.

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.

• Bend Radius: The minimum bend radius for armored cable remains 25.4 mm (1.0 in), the same as standard cable. However, the armor increases cable stiffness and outer diameter — allow sufficient clearance when routing in confined spaces.

• Weight: Armored cable weighs approximately 103 g/m (standard cable is 34 g/m). For long-distance installations, consider the additional tensile load on connectors and probes.

• Ambient Temperature: If the application environment exceeds +177°C, consider the ETR (Extended Temperature Range) armored hazardous area cable series (e.g., 330190-080-03-05).

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

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): 3.68 mm (0.145 in) standard cable diameter

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

• Hazardous Area Installation Tips: When routing through conduit, use a pull rope or fish tape attached to the cable jacket (not the connector) to avoid stress on the connector protector. If connector protector removal is required for inspection, ensure proper reinstallation to maintain seal integrity and hazardous area certification.
