摘要： A magnetic speed sensor air gap fault-detection arrangement having a two-input AND gate for each of the two-axle trucks of a railway vehicle for conditioning a gap process circuit common to each axle. Each of the gap process circuits of each axle is activated to provide a logical "1" output to an associated two-input AND gate. The associated two-input AND gates each outputs a logical "1" to a respective gap counter circuit when the axle rate reaches a predetermined value. The respective gap counter circuits count the logical "1's" and activate an associated gap fault check circuit to reset the respective gap counter circuit and to display an error code and to output a logical "1" signal to the dynamic diagnostic apparatus.
