Product Overview
The Bently Nevada 22810-00-03-05-02 7200 Series Proximity Probe is a non-contact displacement sensing component used in machinery condition monitoring systems. It detects the relative position or movement of a rotating shaft without requiring physical contact between the probe tip and the monitored surface.
The probe is suited to rotating machinery where shaft vibration, radial movement, axial position, or other mechanical displacement must be monitored continuously. Typical installations include turbines, compressors, pumps, motors, and other high-speed rotating equipment where direct contact measurement would introduce mechanical wear or affect the measured shaft.
As part of the Bently Nevada 7200 Series proximity measurement system, the probe works with the associated extension cable and proximity signal-conditioning equipment. The probe establishes the sensing point near the rotating target, while the rest of the monitoring chain converts the probe’s electrical response into usable machinery condition information.
For commissioning and maintenance, correct probe installation is critical. Probe positioning, target surface condition, cable connections, and the associated monitoring electronics all affect measurement quality. Engineers typically verify the complete probe-to-monitoring chain when investigating abnormal vibration or shaft-position readings.

Working Principle
The 22810-00-03-05-02 operates as part of an eddy-current proximity measurement chain. The probe is positioned near the conductive target, normally a rotating shaft surface, and generates a high-frequency electromagnetic field at the sensing tip.
Rotating Shaft → 7200 Series Proximity Probe → Extension Cable → Proximity Signal Conditioner → Monitoring System
As the distance between the probe tip and shaft changes, the electrical characteristics of the probe circuit change accordingly. The associated signal-conditioning equipment converts this change into a usable electrical measurement representing shaft position or movement.
The probe itself does not calculate vibration severity or make machinery protection decisions. Those functions are handled by the downstream signal-conditioning and monitoring equipment.
Typical measurement applications include:
- Shaft radial displacement
- Shaft vibration
- Axial position monitoring
- Rotating-shaft movement
- Machinery condition monitoring
- Protective monitoring applications
Correct probe gap and alignment are essential because an incorrect installation position can affect the measurement range and introduce erroneous readings.
Role in a Bently Nevada 7200 Series Monitoring Architecture
The 22810-00-03-05-02 occupies the sensing layer of the machinery monitoring system. It establishes the physical measurement point at the rotating machine, while the associated electronics and monitoring equipment process and evaluate the resulting signal.
Rotating Machine → Proximity Probe → Extension Cable → Signal Conditioner → Monitoring / Protection System
| System Element | Function |
|---|---|
| Rotating Shaft | Provides the mechanical target |
| 22810-00-03-05-02 | Detects shaft-to-probe displacement |
| Extension Cable | Connects probe to associated electronics |
| Signal Conditioner | Processes the probe electrical signal |
| Monitoring System | Displays and evaluates machinery condition |
| Protection System | Initiates configured protective actions |
| Plant Control System | Uses available machinery status information |
The probe is therefore one component of a complete measurement channel rather than an independent vibration-monitoring instrument.
Industrial Applications
| Application | Typical Use |
|---|---|
| Steam Turbines | Shaft vibration and displacement monitoring |
| Gas Turbines | Rotating shaft condition monitoring |
| Compressors | Shaft movement and machinery protection |
| Centrifugal Pumps | Rotating equipment condition monitoring |
| Motors | Shaft movement and vibration measurement |
| Industrial Fans | Rotating shaft monitoring |
| Power Generation | Continuous machinery condition monitoring |
| Process Machinery | Critical rotating-equipment supervision |
Installation and Maintenance
- Verify that the 22810-00-03-05-02 is compatible with the intended 7200 Series measurement channel.
- Install the probe in the specified machinery mounting location.
- Ensure the probe tip is correctly oriented toward the monitored shaft surface.
- Set and verify the required probe-to-target gap during commissioning.
- Check that the shaft target surface is suitable for proximity measurement.
- Route the probe cable away from unnecessary mechanical stress and interference sources.
- Verify all probe and extension-cable connections before starting the machine.
- Confirm the signal-conditioning equipment is correctly connected to the monitoring system.
- Check the initial measurement signal before placing the machinery into normal operation.
- Compare probe readings with expected shaft movement and machine operating conditions.
- Inspect the probe, cable, and mounting hardware during scheduled machinery maintenance.
- After probe replacement, verify the probe gap, wiring, signal output, and monitoring-channel response before returning the machine to service.
When troubleshooting abnormal readings, inspect the complete measurement chain. A problem can originate from probe positioning, shaft condition, cabling, signal-conditioning electronics, or the monitoring channel rather than from the probe alone.

Technical FAQs
What does the 22810-00-03-05-02 proximity probe measure?
The probe detects changes in the distance between its sensing tip and the conductive rotating target. Depending on the monitoring configuration, this measurement can be used for shaft displacement, vibration, or shaft-position monitoring.
Why is probe gap important during installation?
The probe gap determines the operating point of the proximity measurement channel. An incorrect gap can reduce measurement accuracy or move the probe outside the intended measurement range, so the installation gap should be established according to the applicable system requirements.
Does the probe directly display vibration values?
No. The probe is the sensing element in the measurement chain. Its electrical response is processed by the associated signal-conditioning and monitoring equipment, which then provides the usable machinery measurement.
What should be checked when a proximity channel shows an abnormal reading?
Check the probe position and gap first, followed by the probe cable, extension connection, signal-conditioning equipment, and monitoring channel. The shaft target surface and actual machine operating condition should also be considered when diagnosing unexpected measurements.
