Sensor assembly

摘要

The invention relates to a means of enabling inspection of engineering components, such as rails used in the railway industry.;A rail inspection device comprises a sensor (24) and a compliant spacer (26). The compliant spacer (26) has an inner surface and outer surface. The sensor (24) is urged against the inner surface of the spacer (26) and, when in use, the outer surface of the spacer (26) is in contact with the rail under inspection.

主权项

1. An inspection device for a rail of a railway comprising:
a circular compliant spacer having an inner surface and an outer surface, wherein the circular compliant spacer is a tire configured to roll along a rail under inspection; and a spring-loaded electromagnetic sensor positioned inside the circular compliant spacer, wherein the sensor is urged into contact with the inner surface of the circular compliant spacer and toward the rail under inspection, and wherein, in use, the outer surface of the circular compliant spacer is in rolling contact with the surface of the rail under inspection.
