Product Overview
The Bently Nevada 45358-09 Extension Cable is a cable assembly used to extend the electrical connection between compatible Bently Nevada monitoring components. It forms part of the interconnection path between field-installed instrumentation and associated signal-conditioning or monitoring equipment.
In rotating machinery installations, sensing components are often positioned close to bearings, shafts, housings, or other measurement points while monitoring electronics are located in a control cabinet or machinery monitoring rack. The extension cable provides the additional connection length needed to accommodate this physical arrangement.
The 9-meter cable length is suited to installations where the sensing point and receiving equipment are separated by a considerable distance. Proper routing is particularly important around rotating machinery because vibration, mechanical movement, abrasion, and installation constraints can place stress on long cable runs.
The 45358-09 is a passive connection component. It does not independently measure machinery conditions, process sensor signals, or generate protection decisions. Its condition should therefore be evaluated as part of the complete sensor-to-monitoring signal path.

Product Features
- Extension cable for compatible Bently Nevada monitoring equipment.
- Provides additional cable reach between connected monitoring components.
- 9-meter cable length for installations with separated equipment locations.
- Forms part of the electrical signal path in machinery monitoring systems.

- Applicable to maintenance and replacement of compatible monitoring-system wiring.
- Requires verification of connector and system compatibility before installation.
Working Principle
The 45358-09 provides a continuous electrical path between the connected monitoring components. A signal generated by the associated sensor or instrumentation passes through the cable toward the corresponding signal-conditioning or monitoring equipment.
Field Sensor / Monitoring Component → 45358-09 Extension Cable → Signal Conditioning / Monitoring Equipment → Monitoring System
The cable itself does not interpret or modify the machinery condition being measured. Its purpose is to preserve the required electrical connection across the physical distance between the two compatible connection points.
Cable integrity is therefore important to overall measurement performance. An open conductor, damaged insulation, loose connector, poor termination, or intermittent connection can interrupt the signal path and may appear as a sensor or monitoring-system fault.
Role in a Bently Nevada Machinery Monitoring Architecture
The 45358-09 occupies the interconnection layer between field instrumentation and the downstream monitoring equipment. Its extended cable route allows compatible monitoring components to be installed according to the physical layout of the machinery and control facility.
Rotating Machinery → Sensor / Field Instrumentation → 45358-09 → Signal Conditioning → Machinery Monitoring System → Alarm / Protection
| System Element | Function |
|---|---|
| Rotating Machinery | Produces the mechanical condition being monitored |
| Sensor / Instrumentation | Detects the relevant machinery condition |
| 45358-09 | Extends the electrical signal connection |
| Signal Conditioning | Converts or conditions the sensor signal |
| Machinery Monitoring System | Evaluates the measurement information |
| Alarm / Protection System | Provides configured indication or protective action |
The extension cable should be checked together with the sensor, connectors, signal-conditioning equipment, and monitoring input when troubleshooting an abnormal channel.
Industrial Applications
| Application | Typical Use |
|---|---|
| Turbine Monitoring | Extending sensor connections to monitoring equipment |
| Compressor Monitoring | Field-to-monitor signal routing |
| Generator Monitoring | Connecting machinery sensors with monitoring systems |
| Pump Condition Monitoring | Extended sensor wiring from pump equipment |
| Bearing Monitoring | Connecting sensors positioned near bearing housings |
| Rotating Machinery | Long-distance instrumentation interconnection |
| Centralized Monitoring Systems | Routing field signals to a remote monitoring cabinet |
| Machinery Maintenance | Replacement of damaged or aged extension cables |
Installation and Maintenance
- Verify the complete 45358-09 part number before installation or replacement.
- Confirm that the cable is compatible with the connected Bently Nevada monitoring components.
- Isolate the relevant machinery or monitoring circuit according to the applicable maintenance procedure.
- Identify and document both cable endpoints before disconnecting the existing assembly.
- Inspect the cable jacket, connectors, and termination points for visible damage.
- Plan the 9-meter cable route to avoid unnecessary mechanical stress and movement.
- Protect the cable from sharp edges, crushing points, abrasion, and excessive bending.
- Keep the cable away from avoidable sources of electrical interference where practical.
- Verify that both connectors or terminations are correctly aligned and fully seated.
- Check the monitoring channel for signal continuity and stable operation after installation.
- If an intermittent signal occurs, inspect the complete cable route together with the sensor and monitoring input.
- After replacement, perform a functional test of the complete monitoring channel before returning the machinery to normal operation.

Technical FAQs
When is the 45358-09 preferable to a shorter extension cable?
The 45358-09 is suitable when the physical installation requires a 9-meter connection between the compatible components. Cable length should be considered together with connector configuration, sensor type, and the requirements of the complete monitoring channel.
Can cable length affect a machinery monitoring signal?
Cable length can be relevant to the electrical characteristics of a monitoring circuit, depending on the sensor and receiving electronics. The specified cable arrangement should therefore be maintained unless an alternative configuration has been confirmed as compatible with the complete measurement system.
What should be checked if a monitoring channel becomes intermittent after installing the cable?
Inspect both terminations first, followed by the cable route for abrasion, crushing, excessive bending, or mechanical stress. The associated sensor and monitoring input should then be checked to determine whether the fault is within the cable or another part of the signal chain.
Can the 45358-09 be used as a general-purpose replacement cable?
It should not be selected solely by length or physical appearance. Connector arrangement, electrical characteristics, connected sensor or instrument, and compatibility with the associated Bently Nevada monitoring equipment should be verified before substitution.
