Replaceable Delay Line Transducers

A replaceable delay line transducer has a single element and is heavily damped so that, when used with a replaceable delay line, it provides excellent near-surface resolution. Their higher frequency is also ideal for measuring very thin materials or locating small flaws using the direct contact method. Many styles are available, and they are commonly used for precision thickness gaging, straight beam flaw detection, and inspecting parts with limited contact areas.
