Product Overview
The Bently Nevada 22811-00-03-10-02 is a 7200 Proximity Transducer Cable used within Bently Nevada machinery monitoring systems to connect a compatible proximity probe with its associated Proximitor sensor. The cable forms the signal path between the machine-side sensing element and the signal-conditioning electronics.
In a typical 7200 Series installation, the proximity probe is positioned close to a rotating shaft, thrust collar, or other conductive target. As the target moves relative to the probe, the transducer system generates an electrical signal that must be transferred to the Proximitor sensor. The 22811-00-03-10-02 serves this interconnection function.
Cable selection is part of the overall proximity transducer configuration. The cable must be compatible with the installed probe, Proximitor sensor, connector arrangement, and monitoring system. Using the correct cable configuration helps maintain the intended electrical characteristics of the complete measurement chain.
The 22811-00-03-10-02 can therefore be used for maintenance replacement on existing 7200 Series installations as well as for machinery monitoring assemblies where compatible 7200 Series components are being installed.

Product Features
- 7200 Series proximity transducer cable for machinery monitoring applications.
- Connects compatible proximity probes with associated signal-conditioning electronics.
- Carries the electrical output of the proximity sensing element through the transducer signal chain.
- Suitable for shaft displacement, vibration, and position monitoring systems.
- Intended for use with compatible Bently Nevada 7200 Series components.
- Supports replacement of cables in established machinery monitoring installations.
- Suitable for rotating equipment where non-contact proximity measurements are required.
- Requires correct matching with the associated probe and Proximitor sensor.
Working Principle
The 22811-00-03-10-02 acts as an interconnection element rather than a sensing device. The proximity probe performs the actual non-contact detection of movement between the probe tip and conductive machine target, while the cable transfers the resulting electrical signal to the Proximitor sensor.
Proximity Probe → 22811-00-03-10-02 → Proximitor Sensor → Machinery Monitor
The signal path generally operates in this sequence:
- The proximity probe detects changes in the gap between its sensing tip and the conductive target.
- Movement of the target changes the electrical characteristics of the proximity transducer circuit.
- The 22811-00-03-10-02 transfers the resulting signal from the probe toward the Proximitor sensor.
- The Proximitor sensor conditions the signal and generates the corresponding monitoring output.
- The machinery monitor receives the conditioned signal for evaluation.
- The resulting data can support vibration, radial position, axial position, or machinery protection functions depending on the installed monitoring configuration.
Because the cable forms part of the electrical transducer path, its compatibility with the probe and Proximitor sensor should be confirmed before replacement.
Role in a 7200 Series Machinery Monitoring Architecture
The 22811-00-03-10-02 occupies the connection stage between the machine-mounted proximity probe and the Proximitor sensor.
Machine Target → Proximity Probe → 22811-00-03-10-02 → Proximitor Sensor → Machinery Monitor
| System Element | Function |
|---|---|
| Machine Shaft / Target | Provides the conductive target being monitored |
| Proximity Probe | Detects changes in target position or movement |
| 22811-00-03-10-02 | Transfers the probe signal to the Proximitor sensor |
| Proximitor Sensor | Conditions the proximity transducer signal |
| Machinery Monitor | Processes the resulting machinery measurement |
| Machinery Protection System | Generates configured alarms and protective actions |
| Plant Monitoring System | Displays, records, and trends machinery condition data |
Industrial Applications
| Application | Typical Use |
|---|---|
| Steam Turbine Machinery | Shaft vibration and position monitoring |
| Gas Turbine Equipment | Connection of proximity measurement circuits |
| Turbo Compressors | Rotor displacement and machinery condition monitoring |
| Centrifugal Compressors | Non-contact shaft movement measurement |
| Large Electric Motors | Monitoring of rotating shaft movement |
| Generating Equipment | Rotor position and vibration monitoring |
| Centrifugal Pumps | Monitoring rotating components and shaft behavior |
| Industrial Blowers | Connection of proximity transducer measurement systems |
| Rotating Process Machinery | Continuous condition monitoring and machinery protection |
Installation and Maintenance
- Verify the complete 22811-00-03-10-02 model number before installation.
- Confirm compatibility with the installed 7200 Series proximity probe and Proximitor sensor.
- Check the existing transducer configuration before removing the original cable.
- Isolate the associated electrical and machinery systems before performing replacement work.
- Inspect the cable connectors for contamination, corrosion, loose contacts, or physical damage.
- Keep the cable routing clear of unnecessary sources of electrical interference.
- Avoid sharp bends, excessive pulling force, and mechanical stress during installation.
- Secure the cable against movement caused by machine vibration.
- Verify that both ends are connected to the correct transducer components.
- Check the complete probe-to-Proximitor signal path after installation.
- Confirm the monitoring input before returning the machine to normal operation.
- Observe the signal during startup to identify abnormal fluctuations or loss of signal.
- Inspect cable routing and connector condition during scheduled machinery maintenance.
- Replace damaged cables when signal integrity or mechanical condition is questionable.
When a proximity monitoring channel remains unstable after cable replacement, inspect the entire transducer circuit rather than assuming the cable is the only possible cause. Probe condition, Proximitor operation, connectors, grounding, and the monitoring input can all affect the final signal.

Technical FAQs
What does the Bently Nevada 22811-00-03-10-02 connect?
The 22811-00-03-10-02 connects a compatible 7200 Series proximity probe with the associated Proximitor sensor. It carries the electrical signal generated by the probe to the signal-conditioning electronics.
Is the 22811-00-03-10-02 a complete proximity transducer?
No. It is a cable component within the 7200 Series proximity transducer system. A complete measurement arrangement also requires the appropriate proximity probe, Proximitor sensor, and monitoring equipment.
Can this cable be selected independently of the Proximitor sensor?
The cable should not be selected independently. The probe, cable, and Proximitor sensor form an integrated electrical measurement circuit, so the complete configuration should be checked when selecting a replacement cable.
What symptoms can indicate a problem with the proximity transducer cable?
An open or damaged cable can result in a missing, intermittent, or unstable monitoring signal. Connector problems, incorrect cable matching, and faults in the probe or Proximitor sensor can produce similar symptoms, so the complete signal path should be checked during troubleshooting.
