21504-00-12-10-02: 8 mm Proximity Probe for Vibration Monitoring
The 21504-00-12-10-02 is the 8 mm Proximity Probe for Vibration Monitoring covered on this page. The attribute that decides whether it fits the existing installation without modification is 120 mm.
The reason to specify this exact variant is 8 mm proximity probe for vibration monitoring. In a machine protection or condition-monitoring installation 8 mm proximity probe for vibration monitoring is the attribute that decides whether the sensor reaches the target and reads it on the correct gap. A probe or transducer specified to the wrong case length, thread or sensitivity either cannot reach the measured surface or returns vibration values that do not line up with the rest of the train. Confirming 120 mm against the existing mount is therefore the first check before a replacement, not an afterthought.
