Abstract
A rolling search unit including an ultrasonic device and a heat exchanger mounted within a fluid-filled tire may be utilized to perform ultrasonic testing on an underlying railroad rail. The ultrasonic device may transmit or receive ultrasonic beams into or from the railroad rail, and the heat exchanger may be utilized to maintain the temperature of the fluid within the tire at a preferred level or within a preferred range. In such a manner, the results of testing obtained using the rolling search unit may be standardized regardless of the ambient temperature in the environment where the testing is being performed, and regardless of any heat gained or lost by the rolling search unit during operation.
