21508-02-12-05-02: Proximity Probe Vibration Sensor
The 21508-02-12-05-02 is the Proximity Probe Vibration Sensor covered on this page. The attribute that decides whether it fits the existing installation without modification is 0.5 metre (20 inches).
On this unit proximity probe vibration sensor is the figure that decides fit and function. In a machine protection or condition-monitoring installation proximity probe vibration sensor 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 0.5 metre (20 inches) against the existing mount is therefore the first check before a replacement, not an afterthought.
