Applications
The 330130-075-00-00 is designed for applications where accurate proximity signals need to travel reliably between a field-mounted probe and signal-conditioning equipment.
Rotating Machinery Monitoring
The cable can be used as part of proximity-based vibration and position measurement systems installed on critical rotating equipment. It is particularly relevant to machinery where shaft movement and vibration information are essential for condition assessment.
Fluid-Film Bearing Equipment
In machines equipped with fluid-film bearings, proximity measurement systems can provide important information about shaft position and dynamic behavior. The 3300 XL extension cable provides the physical connection required by the measurement chain.
Keyphasor and Speed Measurement
The cable can also form part of installations using Keyphasor-related reference and speed measurements, where consistent signal transmission is important for machinery analysis and monitoring.
Industrial Condition Monitoring
Its triaxial construction and shielded signal path make the cable appropriate for industrial environments where electromagnetic interference can affect instrumentation wiring.
Maintenance and Replacement Projects
The 7.5 m configuration is useful when replacing an existing cable of the same specification or when additional routing distance is required during a machinery monitoring installation.
Advantages
7.5-Meter Reach for Practical Installation
The 7.5-meter cable length provides additional routing distance without requiring an unnecessarily long cable assembly. This makes the 330130-075-00-00 a useful choice for machinery layouts where the monitoring electronics are positioned some distance from the measurement point.
Stable Electrical Characteristics
The 75Ω triaxial design, controlled resistance, and typical capacitance specification support predictable electrical behavior within the intended proximity measurement system. This is important when maintaining consistent monitoring performance.
FEP Insulation for Harsh Environments
FEP insulation is well suited to demanding industrial conditions and supports the cable's broad operating temperature range of -52°C to +177°C.
Secure ClickLoc Connection
Gold-plated ClickLoc coaxial connectors provide a secure connection arrangement while helping resist corrosion. The connector design is intended to simplify installation without requiring complicated connection procedures.
Mechanical Strength
CableLoc construction provides up to 330 N (75 lbf) tensile strength, helping protect the cable-to-connector assembly from mechanical loads encountered during installation and service.
Flexible Cable Routing
With a minimum bend radius of 25.4 mm, the cable can be routed through relatively confined machinery spaces while maintaining the manufacturer's specified installation requirements.
Suitable for EMI/RFI-Sensitive Installations
The triaxial cable construction provides shielding that helps reduce the influence of electromagnetic and radio-frequency interference, an important consideration for industrial measurement circuits.
