Description
Designed for industrial machinery monitoring, the Bently Nevada 2789-144 provides reliable signal transmission within non-contacting displacement and vibration measurement systems. This coaxial proximity probe extension cable connects the proximity probe to the Proximitor sensor, maintaining precise electrical impedance to prevent signal degradation across the measurement loop. It is engineered to withstand the demanding environments of heavy industrial applications, ensuring consistent electrical performance and mechanical durability in critical asset protection systems.
The cable acts as an essential link in the transducer system, preserving the integrity of high-frequency RF signals generated by the Proximitor. By utilizing high-quality shielding, it minimizes susceptibility to external electromagnetic interference (EMI), which is critical for accurate shaft vibration, position, and speed measurements on rotating machinery.
Features
- Engineered specifically for compatibility with Bently Nevada 7200 Series 5mm and 8mm proximity transducer systems.
- Robust coaxial design optimizes signal propagation and minimizes attenuation.
- High-integrity shielding provides effective protection against industrial electromagnetic noise.
- Durable outer jacket material offers resistance to oils, solvents, and environmental degradation.
- Precision connectors ensure secure, low-resistance physical connections.
Applications
- Steam and gas turbine shaft vibration and position monitoring.
- Centrifugal compressor radial vibration and axial thrust measurements.
- Generators, pumps, and gearboxes in power generation and petrochemical plants.
- Industrial machinery protection systems requiring continuous asset health monitoring.

Installation Guidelines
- Maintain the minimum bend radius specified for coaxial cables to prevent internal conductor damage and impedance changes.
- Ensure all connector interfaces are clean, dry, and free from contaminants before mating.
- Utilize connector protectors or self-fusing silicone tape in areas exposed to fluids, moisture, or high humidity.
- Route the extension cable through dedicated conduit or cable trays, separating it from high-voltage AC power lines to avoid electrical noise coupling.
