Model Breakdown: 330130-040-03-05 Configuration Details

Following Bently Nevada’s part number coding system (refer to datasheet Pages 18-19), the fields in this model number represent the following:

Key Configuration Note: The combination of 040, 03, 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, connector protectors, and hazardous area approvals — offering comprehensive mechanical protection, environmental sealing, and intrinsic safety for the cable and connectors in hazardous areas. It represents the premier protection configuration for 5 m IS systems.

Triple Protection Details

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. Connector Protector — Environmental Sealing

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

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.

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.

Benefits of Triple Protection Combination

Selection Tip: This model is the ultimate solution for hazardous area applications requiring resistance to both mechanical impact and environmental ingress. When the installation is located in a classified hazardous area and involves mechanical vibration, impact, abrasion, oil mist, moisture, or conduit routing, this model is the optimal choice.

Approvals & Conditions of Safe Use

Hazardous Area Certifications

330130-040-03-05 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-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

330130-040-03-05 is suitable for the following typical applications:

1. Precise Total Length Matching for 5 m IS Systems + Triple Protection: 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, protector, and hazardous area approvals — the ideal choice for harsh environments in hazardous areas.

2. High Mechanical Stress + Oil Mist Environments in Hazardous Areas: Near compressors, pumps, and gearboxes in refineries and petrochemical plants, cables may be subjected to strong vibration, friction, or accidental impact, while oil mist is present. Armor provides a mechanical safety margin, protectors prevent oil mist from penetrating the connector, and hazardous area approvals ensure safety compliance.

3. Conduit Routing + Moisture Environments in Hazardous Areas: When cables must be routed through metal conduit and the environment is moist or has water vapor, armor protects against sharp edges at conduit ends, protectors ensure connector sealing, and hazardous area approvals maintain system integrity.

4. Intrinsically Safe Monitoring in Extremely Harsh Industrial Environments: On offshore platforms, mines, and chemical plants, equipment faces multiple challenges from mechanical, environmental, and explosive hazards. This model provides comprehensive protection.

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 + protector hazardous area extension cable (e.g., 330130-045-03-05).

• 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.

• 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). Consider the additional tensile load on connectors and probes during installation.

• Ambient Temperature: If the application environment exceeds +177°C, consider the ETR (Extended Temperature Range) armored + protector hazardous area cable series (e.g., 330190-040-03-05).

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 premier protection configuration for 5 m IS systems.

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 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. The armored section can withstand higher pulling forces, but it is still recommended to attach pulling lines to the cable jacket rather than the connector end. After installation, inspect the connector area to ensure the seal is intact.
