Ideal for rotating machinery monitoring in power generation, oil & gas, petrochemical, steel mills, and heavy manufacturing facilities, this extension cable addresses critical challenges such as signal degradation over distance, environmental noise interference, installation flexibility constraints, and system downtime caused by cable failures.

With standardized design and customizable length options, the 19049-04 cable offers exceptional durability, temperature resistance (-40°C to +125°C), chemical resistance, and compatibility with Bently Nevada 3300 XL and 3500 series monitoring systems. Suitable for instrumentation engineers, maintenance teams, OEM integrators, and plant reliability managers. Contact our engineers for application-specific cable selection and technical support.

Core Features & Advantages

Ultra-Low Noise Signal Transmission
Utilizes triple-layer shielding (foil + braid + jacket) and precision impedance control to minimize signal distortion and EMI, ensuring accurate vibration data acquisition even in electrically noisy industrial environments with VFDs, motors, and high-voltage equipment.

Extended Temperature & Chemical Resistance
Operates reliably across -40°C to +125°C temperature range with FEP or PTFE insulation, resistant to oils, solvents, acids, and alkalis commonly found in process industries, reducing replacement frequency and maintenance costs.

Factory-Calibrated Impedance Matching
Each cable is factory-tested and calibrated to maintain consistent 50-ohm impedance throughout its length, eliminating signal reflection and ensuring compatibility with Bently Nevada proximitor systems without field calibration.

Flexible Installation & Routing
Available in multiple standard lengths (3m, 5m, 7.5m, custom lengths upon request), with flexible yet durable construction allowing easy routing through cable trays, conduits, and tight spaces without compromising signal quality.

Robust Mechanical Protection
Features abrasion-resistant outer jacket, strain relief boots, and optional armored versions for high-vibration or mechanically demanding installations, extending service life in rotating machinery applications.

Plug-and-Play Compatibility
Equipped with industry-standard BNC or Bently Nevada proprietary connectors, enabling quick installation, hot-swappable maintenance, and seamless integration with existing monitoring infrastructure.

Typical Application Scenarios

This cable is engineered for applications requiring high signal fidelity, environmental resilience, and long-term reliability, especially in:

Turbine & Generator Vibration Monitoring
Extends proximity probe signals from turbine bearings, generator pedestals, and thrust positions to monitoring racks in control rooms, supporting real-time shaft vibration, eccentricity, and axial position measurement in power plants and combined-cycle facilities.

Compressor & Pump Condition Monitoring
Connects eddy current probes to 3300 XL or 3500 series monitors in centrifugal compressors, reciprocating compressors, and critical pumps across oil & gas, refining, and chemical processing plants, enabling predictive maintenance and avoiding catastrophic failures.

Motor & Gearbox Bearing Surveillance
Facilitates non-contact displacement measurement in large motors, gearboxes, and rolling mills, where cable routing distances exceed standard probe cable lengths, ensuring continuous monitoring without signal loss.

Offshore & Marine Machinery Monitoring
Withstands salt spray, humidity, and temperature cycling in offshore platforms, FPSOs, and marine propulsion systems, providing reliable vibration data for critical rotating equipment in harsh marine environments.

Retrofit & System Expansion Projects
Enables cost-effective extension of existing Bently Nevada monitoring systems when relocating monitors, adding new measurement points, or upgrading control room layouts without replacing entire probe assemblies.

Technical Parameters & Selection Guide

To facilitate engineering design and procurement, we provide standardized specifications and customizable options:

Selection Recommendations:
When selecting extension cables, consider: (1) total signal path length from probe tip to monitor input (including probe cable + extension cable), (2) environmental conditions (temperature extremes, chemical exposure, mechanical stress), (3) installation routing constraints (cable tray, conduit, or direct burial), (4) connector compatibility with existing proximitor and monitor models. For assistance, provide your system model (e.g., 3300 XL, 3500/42M), probe type, required cable length, and installation environment. Our engineers will recommend the optimal configuration and verify system compatibility.

Frequently Asked Questions (FAQ)

Q: How do I connect the Bently Nevada 19049-04 extension cable to my existing proximity probe system?
A: The 19049-04 cable connects between the proximity probe cable (from the probe tip) and the proximitor or monitor input. Ensure connector types match (BNC or Bently Nevada proprietary). Verify total cable length (probe cable + extension cable) does not exceed system maximum (typically 9m for 3300 XL systems). Consult your monitor manual or contact our engineers for specific system compatibility.

Q: What is the maximum number of extension cables I can daisy-chain for a single probe?
A: We do not recommend daisy-chaining multiple extension cables due to cumulative signal degradation and impedance mismatch risks. Instead, order a single custom-length cable matching your required distance. For distances exceeding standard offerings, consult our engineering team for signal integrity analysis and possible proximitor relocation.

Q: What energy savings or performance improvement can I expect from using low-noise extension cables?
A: While extension cables do not directly reduce energy consumption, they ensure accurate vibration data acquisition, enabling predictive maintenance strategies that prevent unplanned downtime, reduce emergency repairs, and optimize machinery operating conditions—indirectly contributing to energy efficiency and cost savings. Reliable signal transmission also minimizes false alarms and unnecessary shutdowns.

Q: What are the environmental requirements for installing the 19049-04 cable? What is its protection rating?
A: The cable is rated for -40°C to +125°C ambient temperature, suitable for indoor and outdoor industrial environments. While the cable itself does not have an IP rating (as it is not an enclosure), its FEP/PTFE insulation and sealed connectors provide excellent moisture and chemical resistance. For submersion or direct burial applications, specify armored or conduit-protected versions at order.

Q: Can the cable support remote monitoring and data acquisition? What communication protocols are compatible?
A: The 19049-04 cable transmits analog proximity probe signals to Bently Nevada monitors (proximitors or rack-mounted modules). These monitors then output processed data via 4-20mA, relay contacts, or digital protocols (Modbus RTU/TCP, Ethernet/IP, OPC) to DCS, PLC, or SCADA systems for remote monitoring. The cable itself is passive and protocol-agnostic; digital communication depends on the connected monitor model.

Q: Is the cable compatible with non-Bently Nevada proximity probe systems?
A: The 19049-04 is optimized for Bently Nevada eddy current proximity probe systems (3300 XL, 3500 series). While it may physically connect to other 50-ohm coaxial systems, electrical compatibility (voltage levels, frequency response, connector pinouts) must be verified. For third-party systems, provide probe and monitor specifications for compatibility assessment.
