Stainless-steel armor protection
Flexible stainless-steel armor surrounds the integral coaxial lead and transfers mechanical strain through the ferrule instead of directly into the cable jacket.
01
Product Information
Stainless-steel armor distinguishes Bently Nevada 21505-00-44-10-02, a 7200 Series 8 mm standard-mount proximity probe that forms the sensing end of a matched 7200 transducer system. The armor protects the integral coaxial lead as the probe detects shaft-to-tip distance at a conductive target.
Bently Nevada 21505-00-44-10-02 combines a 4.4 inch threaded case with no unthreaded tip section and a 1.0 m lead. The case establishes the mounting reach, while the miniature coaxial connector transfers the unconditioned probe response to the extension cable without changing the calibrated system length.
Routing for Bently Nevada 21505-00-44-10-02 must support the armored lead near the probe and avoid forcing the armor ferrule against the case. Once the matching 7200 extension cable and Proximitor are connected, the chain supplies the calibrated displacement output and frequency response specified for the system.

Key Features
Bently Nevada 21505-00-44-10-02 combines a protected integral lead, defined standard-mount geometry and a miniature coaxial connection in one 7200 Series probe.
Stable standard-mount geometry
The 4.4 inch threaded case with no unthreaded tip section provides a fixed mechanical reach for the 3/8-24 mounting interface.
Matched 7200 connection
The miniature coaxial connector hands the probe response to the compatible 7200 extension cable while preserving the calibrated transducer path.
04
System Integration
Bently Nevada 21505-00-44-10-02 is the target-facing element of a 7200 measurement chain; its armor protects the lead, but the extension cable and Proximitor still provide the electrical completion.
Probe-to-cable handoff
The integral coaxial lead carries the unconditioned probe response to the miniature connector, where the matching 7200 extension cable continues the calibrated path.
Conditioning stage
The compatible Proximitor excites the probe and converts the impedance change into the proportional voltage received by the monitor.
Mechanical and electrical match
The 4.4 inch case determines target reach, while the complete cable length determines electrical calibration; both must match the installed record.

Product Questions
01What does the armor change on Bently Nevada 21505-00-44-10-02?
The stainless-steel armor on Bently Nevada 21505-00-44-10-02 protects the integral coaxial lead from mechanical damage; it does not change the requirement for a matched 7200 extension cable and Proximitor.
02Where should Bently Nevada 21505-00-44-10-02 be supported?
Support Bently Nevada 21505-00-44-10-02 at the threaded case and along the cable route, leaving the armor ferrule free of side load so tightening does not alter the probe gap.
03Why can Bently Nevada 21505-00-44-10-02 still suffer cable faults despite its armor?
Armor on Bently Nevada 21505-00-44-10-02 resists abrasion but cannot prevent damage from excessive bending, torsion, crushed ferrules or contaminated coaxial connectors.
04How is the 4.4 inch case on Bently Nevada 21505-00-44-10-02 verified?
Measure the mounting depth and target position for Bently Nevada 21505-00-44-10-02, then confirm that the zero unthreaded section and 4.4 inch case leave enough adjustment for final gap setting.
05What should be checked after reconnecting Bently Nevada 21505-00-44-10-02?
After reconnecting Bently Nevada 21505-00-44-10-02, verify connector cleanliness, cable continuity, Proximitor supply and static gap voltage before using the vibration signal.
06Can the armored lead of Bently Nevada 21505-00-44-10-02 be shortened?
No. The 1.0 m lead of Bently Nevada 21505-00-44-10-02 is part of the matched 7200 system length; shortening or splicing it changes the electrical relationship used for calibration.
