21505-000-012-05-02 Bently Nevada vibration probe
Description
The Bently Nevada 21505-00-12-05-02-(variant) family — including part numbers like 21505-00-12-05-02 — refers to industrial vibration proximity probes from Bently Nevada
used in non-contact vibration and shaft position monitoring systems. Probes in this series are designed for rotating machinery condition monitoring, delivering precise
displacement and vibration data to monitoring electronics for machine protection and diagnostics.

FAQ 1. What does this vibration probe measure? This probe measures vibration and displacement by sensing changes in the gap between the probe tip and a conductive rotating or moving target. It converts the physical motion into an electrical signal that upstream electronics can interpret. 2. How does it work? It uses eddy-current (non-contact) technology — an electromagnetic field from the probe interacts with the conductive target, and changes in gap are reflected in the probe’s output signal, which is then processed by a signal conditioner. 3. Where is it typically installed? The probe is mounted near a rotating shaft or other moving part using a threaded or standard mounting arrangement. The exact gap between the probe and target must be set according to the manufacturer’s guidelines for accurate measurement. |
