Product Overview
The Bently Nevada 22810-00-04-10-02 is a 7200 Series proximity probe used for non-contact measurement of shaft position, radial vibration, and other mechanical movement in rotating machinery. It is typically installed as part of a proximity measurement chain where the probe senses changes in the distance between the probe tip and a conductive machine target.
In turbine, compressor, pump, motor, and generator applications, the probe is mounted close to the monitored shaft or other rotating target. As the shaft moves relative to the probe, the measurement system detects the corresponding change and converts it into a usable vibration or position signal for machinery monitoring.
The 7200 Series probe is particularly suited to applications where continuous monitoring of rotating components is required. Typical installations include bearing housings, turbine shafts, compressor trains, and other critical rotating equipment where changes in shaft position or vibration can indicate mechanical problems.
The 22810-00-04-10-02 can be integrated into a complete proximity monitoring system with the appropriate driver and monitoring electronics. In an operating plant, the probe normally remains installed while maintenance personnel use the resulting measurement data for condition monitoring, alarm management, and troubleshooting.

Product Features
- 7200 Series proximity probe for rotating machinery monitoring.

- Applicable to turbine, compressor, pump, motor, and generator monitoring systems.
Working Principle
The 22810-00-04-10-02 operates as the sensing element of an eddy-current proximity measurement system. The probe is positioned near a conductive rotating shaft or target surface. When the shaft moves toward or away from the probe tip, the electrical characteristics of the sensing field change.
The associated driver electronics interpret this change as a variation in the probe-to-target gap. The resulting signal can then be processed by a machinery monitoring system to determine shaft vibration, radial movement, or shaft position.
Rotating Shaft → 22810-00-04-10-02 Probe → Proximity Driver → Machinery Monitoring System → Alarm / Condition Monitoring
Typical measurement functions include:
- Radial shaft vibration monitoring
- Shaft displacement measurement
- Relative shaft position monitoring
- Mechanical movement detection
- Continuous condition monitoring of rotating equipment
Correct probe positioning is important because the measurement depends on the physical relationship between the probe tip and the monitored target surface.
Role in a Rotating Machinery Control Architecture
The probe normally forms the front-end sensing point of a machinery protection or condition monitoring channel. It does not independently analyze machine condition; instead, it supplies the displacement information required by downstream electronics.
Shaft Target → Proximity Probe → Driver / Signal Conditioning → Monitoring System → Control Room
| System Element | Function |
|---|---|
| Rotating Shaft | Provides the monitored mechanical target |
| 22810-00-04-10-02 | Detects changes in shaft-to-probe distance |
| Proximity Driver | Supplies probe excitation and conditions the measurement signal |
| Monitoring Module | Processes vibration or position information |
| Protection System | Generates alarms or protective actions when configured limits are exceeded |
| DCS / Control System | Receives relevant monitoring information for plant operation |
This architecture allows the probe to remain physically close to the machine while monitoring and protection electronics can be installed in the equipment cabinet.
Industrial Applications
| Application | Typical Use |
|---|---|
| Steam Turbines | Shaft vibration and relative displacement monitoring |
| Gas Turbines | Rotating shaft condition monitoring |
| Compressors | Radial vibration and shaft movement measurement |
| Pumps | Monitoring shaft movement and mechanical condition |
| Motors | Detection of abnormal shaft vibration |
| Generators | Rotor movement and vibration monitoring |
| Gearbox Systems | Monitoring rotating shaft behavior |
| Industrial Machinery | Continuous displacement and vibration measurement |
Installation and Maintenance
- Install the probe in a rigid mounting position suitable for the monitored shaft or target.
- Maintain the required probe-to-target relationship during installation.
- Ensure the probe mounting arrangement does not introduce excessive mechanical movement.
- Keep the sensing area free from unnecessary contamination or physical obstruction.
- Route the probe cable away from sources of excessive mechanical damage.
- Protect the cable from sharp edges, excessive bending, and unsuitable routing conditions.
- Verify the probe connection to the associated driver before commissioning.
- Check the measurement channel for stable output during initial startup.
- Compare the measurement with expected machinery operating conditions.
- Inspect the probe installation during scheduled machinery maintenance.
- Investigate abnormal signal changes together with other machine condition data.
- Replace the probe if physical damage, unstable measurement, or installation-related problems are confirmed.
For critical rotating equipment, probe condition should be checked as part of the overall machinery monitoring maintenance program rather than treated as an isolated component.
