21505-00-40-10-02: Proximity Probe Vibration Transducer
The 21505-00-40-10-02 is the Proximity Probe Vibration Transducer covered on this page. The attribute that decides whether it fits the existing installation without modification is 4.0 in.
The reason to specify this exact variant is proximity probe vibration transducer. In a machine protection or condition-monitoring installation proximity probe vibration transducer 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 4.0 in against the existing mount is therefore the first check before a replacement, not an afterthought.
Configuration From the Published Data
This unit is documented as a Proximity Probe Vibration Transducer. The configuration carried in the order code is: Threads: 3/8-24; Unthreaded Length: 0 mm; Overall Case Length: 4.0 in; Total Length: 1.0 metre (39 inches) Tolerance: +0.25 metre, -0.10 metre; Connector: miniature male coaxial. These are the figures to confirm against the existing mount and monitor before ordering a replacement.
