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