Technical Parameters & Selection Guide

To ensure optimal system performance, verify compatibility with your existing Bently Nevada 3300 series configuration. Key specifications include:

Selection Considerations: When specifying extension cables, account for total cable run length (probe cable + extension), mounting clearances, connector orientation, and environmental factors. For installations requiring different lengths or custom configurations, consult with our engineering team to ensure system capacitance remains within proximity system specifications.

Extended Capabilities & System Integration

• Daisy-Chain Configuration: Multiple extension cables can be connected in series for longer runs, provided total system capacitance stays within proximity system limits (typically 1000-1500 pF).
• Retrofit Compatibility: Direct replacement for existing Bently Nevada extension cables in legacy installations, enabling maintenance without system reconfiguration.
• Multi-Channel Systems: Suitable for use in multi-probe monitoring configurations where consistent cable specifications across all channels ensure balanced system response.
• Harsh Environment Deployment: Cable construction supports installation in areas with exposure to moisture, dust, vibration, and moderate chemical exposure typical of industrial facilities.

Frequently Asked Questions (FAQ)

Q: How does the 3300/35 extension cable integrate with existing Bently Nevada proximity systems?
A: The cable features standard BNC connectors that directly mate with 3300 series proximity probes and extension cables. Simply connect between the probe cable and the cable run to the proximitor or monitor, ensuring secure BNC coupling. Verify total system capacitance remains within your specific proximitor model's specifications.

Q: What is the maximum number of extension cables that can be connected in series?
A: The limiting factor is total system capacitance, not cable quantity. Most 3300 series proximitors support 1000-1500 pF total capacitance. Each 1-meter extension adds approximately 30-35 pF. Calculate your total cable run (probe + extensions) and verify against your proximitor specifications. For runs exceeding 10 meters, consult factory guidelines.

Q: Can this cable be used in hazardous area classifications?
A: The cable itself is passive and suitable for use in classified areas when installed as part of a properly certified intrinsically safe or explosion-proof monitoring system. Verify that your complete system (proximitor, barriers, cabling) meets applicable hazardous location certifications (ATEX, IECEx, NEC 500/505) for your specific installation.

Q: What environmental conditions can the cable withstand?
A: The cable is rated for industrial environments with operating temperatures typically from -40°C to +85°C, and features shielding to resist electromagnetic interference. The outer jacket provides protection against moisture, oils, and moderate chemical exposure. For extreme conditions (high temperature, corrosive atmospheres, submersion), contact our engineering team for specialized cable recommendations.

Q: How do I verify signal quality after installing extension cables?
A: Use a Bently Nevada TK-3 test kit or equivalent to measure gap voltage and verify linear range. Compare readings with and without the extension cable to confirm minimal signal degradation. Total system capacitance can be measured with an LCR meter. Consult your proximitor manual for acceptable voltage and capacitance ranges.

Q: Is this cable compatible with non-Bently Nevada proximity systems?
A: While the cable uses standard BNC connectors and 50-ohm impedance common to many proximity systems, optimal performance is guaranteed only with Bently Nevada 3300 series equipment. Using with other manufacturers' systems may work but could affect measurement accuracy or void warranties. Verify electrical compatibility before cross-application use.
