The Bently Nevada 21505-00-44-10-02 7200 8 mm Standard Mount Armored Probe is a proximity sensing component intended for rotating-machinery monitoring applications. It provides a non-contact measurement method that allows the associated monitoring system to observe shaft movement without mechanical contact with the rotating component.
Proximity probes are widely used on turbines, compressors, pumps, motors, generators, and other rotating assets where shaft movement can provide important information about machine condition. Relative shaft vibration and position measurements can be used as part of a broader machinery-protection strategy.
The 7200 8 mm configuration combines an 8 mm probe arrangement with armored construction. This is particularly useful in installations where the probe must withstand a demanding industrial environment while maintaining a stable sensing relationship with the rotating target.
For maintenance engineers, the exact part number is important when replacing an existing probe. Small differences in probe construction, mounting configuration, cable arrangement, or electrical characteristics can affect compatibility with the installed monitoring system.
During installation, the probe should be mechanically secure and correctly positioned relative to the shaft. The sensing gap must be established according to the requirements of the associated monitoring system. Once installed, the complete signal path should be checked before the monitored machine is returned to normal operation.

Machinery protection systems
For replacement work, selecting a proximity probe should be based on the complete part number rather than probe diameter alone. Mounting style, armored construction, cable length, electrical compatibility, sensing gap, and the associated monitoring electronics all need to match the installed system.
Applications
The Bently Nevada 21505-00-44-10-02 7200 8 mm Standard Mount Armored Probe is designed for non-contact monitoring of rotating machinery. As part of a proximity measurement system, the probe detects changes in the distance between its sensing tip and a conductive rotating target, allowing the associated monitoring equipment to evaluate shaft movement and machine condition.
Typical applications include:
Steam turbines
Gas turbines
Centrifugal compressors
Industrial pumps
Electric motors
Generators
Gearboxes
Rotating shafts
Industrial machinery protection
Predictive maintenance systems
The armored construction makes this probe particularly suitable for installations where additional mechanical protection is desirable. The 8 mm sensing format provides a practical solution for machinery-monitoring arrangements that require non-contact shaft measurement.
Advantages
The 21505-00-44-10-02 combines the non-contact measurement principle of a proximity probe with an armored mechanical construction. This makes it a useful component for established Bently Nevada 7200-series monitoring installations.
Non-Contact Shaft Measurement
The probe operates without physically contacting the rotating shaft, eliminating mechanical contact between the sensing tip and the target during normal operation.
8 mm Probe Configuration
The 8 mm design is suitable for a broad range of rotating-machinery monitoring arrangements where shaft vibration or position needs to be observed.
Armored Construction
The armored design provides additional protection to the probe assembly and cable route in demanding industrial environments.
Useful for Machinery Protection
When connected to compatible monitoring electronics, the probe can contribute to continuous monitoring of shaft position and relative vibration.
1-Meter Total Length
The specified 1-meter total length provides practical flexibility for probe installation and cable routing within machinery-monitoring systems.
Maintenance-Friendly Replacement
For existing 7200-series installations, using the correct probe configuration can simplify replacement work and help restore the original measurement arrangement.
Technical FAQs
1. What is the Bently Nevada 21505-00-44-10-02 used for?
It is a 7200 series 8 mm proximity probe designed for non-contact measurement of rotating machinery conditions such as shaft position and relative vibration.
2. What does the 8 mm designation refer to?
The 8 mm designation identifies the probe's nominal sensing diameter or probe configuration. The complete part number should still be used when identifying the correct replacement.
3. What is the purpose of the armored probe construction?
The armored construction provides additional mechanical protection for the probe assembly and associated cable routing, which can be useful in demanding machinery environments.
4. Does the probe physically contact the shaft?
No. A proximity probe operates with a controlled clearance between the sensing tip and the conductive shaft target.
5. Why is the probe gap important?
The gap establishes the operating point of the proximity measurement. An incorrect gap can result in an unsuitable signal level, reduced measurement accuracy, or unreliable monitoring.
6. What can cause a fluctuating proximity-probe signal?
Possible causes include incorrect probe gap, damaged cable, loose connections, mechanical movement of the probe, target-surface irregularities, electrical interference, or problems with the associated signal-conditioning electronics.
7. Can the probe be used to monitor shaft vibration?
Yes. When connected to compatible proximity monitoring electronics, the probe can provide a measurement of shaft-relative movement that can be used for vibration monitoring.
8. What should be checked before replacing an existing 7200 probe?
Verify the complete part number, probe diameter, mounting arrangement, total length, armored construction, target characteristics, and compatibility with the existing monitoring electronics.
9. What should be done if a new probe produces an abnormal reading?
Check the mechanical installation and probe gap first. Then inspect cable connections, transducer operation, monitoring-channel configuration, and the target surface before concluding that the replacement probe is defective.
10. How should the probe be commissioned after installation?
Confirm secure mounting, correct probe alignment, appropriate gap, cable integrity, and transducer connections. The monitoring channel should then be checked against a known baseline before normal machine operation.
