Product Overview
The Bently Nevada 22810-00-06-10-02 is a proximity probe from the 7200 Series, used for non-contact measurement of the relative position and movement of a conductive machine target. It is commonly applied to rotating machinery where shaft displacement, vibration, or axial movement needs to be monitored without physically contacting the rotating component.
The probe forms the sensing end of a complete proximity transducer system. It is installed close to the monitored shaft or target surface, while the associated extension cable and Proximitor sensor complete the signal path to the machinery monitoring equipment.
As the distance between the probe tip and the conductive target changes, the electrical characteristics of the sensing field change accordingly. The associated electronics use this change to generate a measurement signal representing the mechanical movement of the target.
The 22810-00-06-10-02 can therefore be used in machinery protection and condition-monitoring installations where continuous shaft movement information is required. When replacing an existing probe, the complete model number, transducer configuration, target material, mounting arrangement, and probe gap should be verified.

Working Principle
The 22810-00-06-10-02 operates using an eddy-current proximity sensing principle. The probe establishes an electromagnetic field at its sensing tip. When a conductive target approaches or moves away from the probe, the resulting change in the electromagnetic interaction is detected by the associated transducer electronics.
Conductive Machine Target → 22810-00-06-10-02 → Extension Cable → Proximitor Sensor → Machinery Monitor
The measurement process involves:
- The probe is positioned at a controlled gap from the machine target.
- The sensing circuit establishes the electromagnetic field required for proximity measurement.
- Shaft movement changes the distance between the target and probe tip.
- The electrical response of the probe changes as the target moves.
- The Proximitor sensor processes the probe response into a usable output signal.
- The monitoring system evaluates the resulting signal for shaft position, vibration, or other displacement-related parameters.
Because the measurement is non-contacting, the probe can continuously observe shaft movement while remaining stationary relative to the machine housing.
Role in a 7200 Series Machinery Monitoring Architecture
The 22810-00-06-10-02 serves as the physical sensing element at the machine end of the 7200 Series proximity measurement chain.

| System Element | Function |
|---|---|
| Machine Shaft / Target | Provides the conductive surface being measured |
| 22810-00-06-10-02 | Detects changes in target-to-probe distance |
| Extension Cable | Carries the probe signal to the associated electronics |
| Proximitor Sensor | Processes the proximity signal |
| Machinery Monitor | Evaluates displacement and vibration information |
| Protection System | Generates alarms or trips when configured limits are exceeded |
| Plant Monitoring System | Provides equipment status and trend information |
Industrial Applications
| Application | Typical Use |
|---|---|
| Steam Turbines | Shaft vibration and position monitoring |
| Gas Turbines | Monitoring rotor movement and shaft condition |
| Compressors | Detecting shaft displacement and dynamic movement |
| Centrifugal Pumps | Monitoring rotating shaft behavior |
| Electric Motors | Shaft vibration and position measurement |

Installation and Maintenance
- Verify the complete 22810-00-06-10-02 model before installation.
- Confirm compatibility with the intended 7200 Series transducer configuration.
- Isolate the associated machinery and electrical circuits before installation.
- Check the probe mounting location and available clearance.
- Confirm that the monitored target provides a suitable conductive surface.
- Establish the required probe-to-target gap during installation.
- Make sure the probe tip cannot contact the rotating shaft during operation.
- Inspect the extension cable and connection points before commissioning.
- Confirm compatibility between the probe, cable, Proximitor sensor, and monitor.
- Check the transducer signal with the machine stopped before starting the equipment.
- Observe the signal during startup and compare it with expected shaft behavior.
- Inspect probe mounting and cable routing during scheduled machinery maintenance.
- Investigate abnormal readings by checking the entire transducer chain rather than replacing the probe immediately.
- Record the probe model and installation gap for future replacement work.
If the output signal is unstable, inspect the probe gap, shaft surface, mounting condition, cable connections, and associated Proximitor sensor. Mechanical runout or target-surface irregularities can also affect the measurement and should be considered during troubleshooting.

Technical FAQs
What is the difference between a proximity probe and a conventional vibration sensor?
A proximity probe measures the relative distance between the stationary probe tip and a conductive machine target. This allows the system to observe shaft position and movement directly, whereas conventional casing-mounted vibration sensors measure vibration at the machine housing.
Where should the 22810-00-06-10-02 normally be installed?
It is normally mounted in a fixed position near the monitored shaft or another suitable conductive target. The probe must be positioned with the appropriate measurement gap and aligned so that normal machine movement does not cause physical contact.
Can the 22810-00-06-10-02 be connected directly to a machinery monitor?
The probe normally forms part of a complete transducer system and requires the appropriate associated electronics, such as the compatible extension cable and Proximitor sensor, before the signal is presented to the machinery monitoring equipment.
Why is the probe gap important during commissioning?
The probe gap establishes the operating point of the proximity measurement. An incorrect gap can produce an abnormal output signal, reduce usable measurement range, or cause inaccurate interpretation of shaft movement. The installation gap should therefore be set according to the applicable transducer-system requirements.
