Core Features & Technical Advantages

Factory-Calibrated Performance
Each cable is calibrated as part of the complete proximity system, ensuring accurate gap voltage output and eliminating field calibration requirements. This reduces commissioning time and maintains measurement traceability.

Low-Noise Coaxial Design
Precision coaxial construction with controlled impedance minimizes signal attenuation and electromagnetic interference pickup, preserving the integrity of low-level proximity sensor signals even in electrically noisy industrial environments.

Extended Reach Capability
The 5-meter length provides installation flexibility for applications where monitors must be located away from the measurement point, such as panel-mounted systems or distributed monitoring architectures.

Robust Industrial Construction
Built with durable jacket materials and strain relief features to withstand vibration, temperature cycling, and mechanical stress typical of turbomachinery installations, reducing maintenance frequency and replacement costs.

Seamless System Integration
Standard BNC connectors ensure plug-and-play compatibility with 3300 XL proximity probes and Proximitor sensors, simplifying installation and enabling quick sensor replacement without system reconfiguration.

Proven Reliability
Manufactured to Bently Nevada quality standards with materials selected for long-term stability, this cable supports continuous operation in mission-critical monitoring applications where downtime is not an option.

Typical Application Scenarios

This extension cable is engineered for installations requiring stable signal transmission over extended distances, particularly in:

Frequently Asked Questions (FAQ)

Q: Can this extension cable be used with other proximity sensor brands?
A: This cable is factory-calibrated specifically for Bently Nevada 3300 XL systems. Using it with other sensor systems may result in measurement errors due to impedance mismatch and calibration incompatibility. For multi-vendor installations, consult our engineers for compatibility assessment.

Q: What is the maximum total cable length for a 3300 XL proximity system?
A: The combined length of proximity probe cable and extension cable should not exceed the system's specified maximum (typically 9 meters for standard configurations). Exceeding this limit can cause signal degradation and measurement inaccuracy. Contact us for extended-range solutions if needed.

Q: How does this cable maintain signal integrity in electrically noisy environments?
A: The low-noise coaxial design with controlled impedance and shielding provides excellent rejection of electromagnetic interference from motors, VFDs, and power cables. Proper grounding and cable routing practices further enhance noise immunity in industrial settings.

Q: Is field calibration required after installing this extension cable?
A: No. The cable is factory-calibrated as part of the complete proximity system. Simply connect it between the probe and Proximitor sensor using the BNC connectors, and the system maintains its original calibration and accuracy specifications.

Q: What environmental conditions can this cable withstand?
A: The cable is rated for -40°C to +85°C operation and features an oil and chemical-resistant jacket suitable for harsh industrial environments. It can withstand typical vibration, humidity, and mechanical stress found in turbomachinery installations.

Q: Can I use multiple extension cables in series to achieve longer distances?
A: Cascading multiple extension cables is not recommended as it may exceed the system's maximum cable length specification and introduce additional connection points that can affect reliability. For applications requiring extended reach beyond 5 meters, contact us for single-length custom cable solutions.
