Product Overview
The Bently Nevada 22810-00-03-10-02 7200 Series Proximity Probe is a non-contact displacement sensing component for rotating machinery monitoring. It is used where shaft movement needs to be measured without placing a mechanical sensor in direct contact with the rotating surface.
The probe is suitable for machinery such as turbines, compressors, pumps, motors, and other rotating equipment where shaft vibration or displacement is monitored as part of a condition-monitoring system. Non-contact sensing is particularly useful on high-speed rotating machinery because the probe does not introduce mechanical contact with the shaft during normal operation.
As part of the Bently Nevada 7200 Series, the probe operates together with the associated extension cable and signal-conditioning equipment. The probe establishes the sensing point at the machine, while downstream electronics process the electrical response and make the measurement available to the monitoring or protection system.
During installation and maintenance, probe position, sensing gap, cable condition, and the associated monitoring channel all need to be considered together. When an unexpected vibration or displacement value appears, checking the complete measurement channel is generally more effective than examining the probe alone.

Working Principle
The 22810-00-03-10-02 operates as the sensing element of a proximity measurement system. The probe generates an electromagnetic field at its sensing tip and responds to changes in the distance between the probe and the conductive shaft target.
Rotating Shaft → 22810-00-03-10-02 Probe → Extension Cable → Signal Conditioning → Monitoring System
As the shaft moves relative to the probe, the electrical characteristics of the sensing circuit change. The associated signal-conditioning equipment converts these changes into a measurement that can be evaluated by the machinery monitoring system.
The probe itself does not perform the final vibration analysis or protection decision. Those functions are handled by the downstream monitoring equipment. The probe provides the physical sensing point required to obtain shaft movement information.
Typical applications include:
- Shaft radial displacement monitoring
- Shaft vibration measurement
- Axial position monitoring
- Rotor movement detection
- Machinery condition monitoring
- Machinery protection channels
Probe installation must maintain the appropriate relationship between the sensing tip and shaft target. Mechanical alignment and the installed probe gap therefore form an important part of the measurement channel.
Role in a Bently Nevada 7200 Series Monitoring Architecture
The 22810-00-03-10-02 occupies the sensing layer of the 7200 Series machinery monitoring architecture. It converts changes in shaft-to-probe distance into an electrical response that can be processed by the associated signal-conditioning and monitoring equipment.
Rotating Machine → Proximity Probe → Extension Cable → Signal Conditioner → Monitoring / Protection System
| System Element | Function |
|---|---|
| Rotating Shaft | Provides the monitored mechanical target |
| 22810-00-03-10-02 | Detects changes in shaft-to-probe distance |
| Extension Cable | Connects the probe to associated electronics |
| Signal Conditioner | Processes the probe electrical response |
| Monitoring System | Evaluates and displays machinery condition |
| Protection System | Performs configured machinery protection |
| Plant Control System | Uses available machinery status information |
The probe therefore forms the front end of the measurement channel, while signal processing and machinery protection occur in the equipment connected downstream.
Industrial Applications
| Application | Typical Use |
|---|---|
| Steam Turbines | Shaft vibration and displacement monitoring |
| Gas Turbines | Rotor movement and machinery condition monitoring |
| Compressors | Shaft displacement monitoring |
| Centrifugal Pumps | Rotating equipment condition monitoring |
| Electric Motors | Shaft movement and vibration measurement |
| Industrial Fans | Rotor monitoring |
| Power Generation | Continuous machinery condition monitoring |
| Process Machinery | Critical rotating-equipment supervision |
Installation and Maintenance
- Confirm that the 22810-00-03-10-02 is compatible with the intended 7200 Series measurement channel.
- Install the probe at the specified machinery measurement location.
- Position the sensing tip correctly relative to the rotating shaft target.
- Establish and verify the required probe-to-target gap during commissioning.
- Check the shaft target surface for conditions that could affect proximity measurement.
- Secure the probe and mounting arrangement to prevent unwanted movement during machine operation.
- Route the probe cable away from excessive mechanical stress and potential interference sources.
- Verify probe and extension-cable connections before starting the machine.
- Confirm that the associated signal-conditioning equipment receives the expected probe signal.
- Check the initial measurement before placing the machine into normal operation.
- Inspect the probe, cable, mounting hardware, and connections during scheduled maintenance.
- After replacing the probe, verify its installation position, gap, wiring, and monitoring-channel response.
If the monitoring channel produces an abnormal reading, check the probe gap and mechanical installation first. Then inspect the cable, signal-conditioning electronics, and monitoring channel before concluding that the probe itself has failed.

Technical FAQs
What is the 22810-00-03-10-02 used to detect?
The probe detects changes in the distance between its sensing tip and a conductive rotating target. The resulting signal can be used for shaft displacement, vibration, or position monitoring depending on the overall measurement configuration.
Why is the probe installed without contacting the shaft?
Non-contact measurement avoids mechanical contact with a high-speed rotating shaft. This allows shaft movement to be monitored continuously without introducing a rubbing sensor element into the rotating assembly.
What components are normally required with the probe?
A complete measurement channel normally includes the proximity probe, the appropriate connection or extension cable, signal-conditioning electronics, and a monitoring or protection system. The exact arrangement depends on the machinery monitoring architecture.
What can cause an incorrect proximity-probe reading?
Incorrect probe gap, poor alignment, damaged cabling, connection problems, unsuitable shaft target conditions, or faults in downstream signal-conditioning equipment can all affect the measurement. The entire channel should be checked when troubleshooting.
