The Sonopen® transducer has a replaceable delay line that is tapered to a small contact area. This transducer makes reliable thickness measurements in applications such as turbine blades, threads on plastic bottle necks, and tight radii on plastic containers. High-temperature Sonopen delay lines are also available.

Standard Delay Lines
Standard delay lines are used in many applications. Special conditions such as high surface temperature, the curvature of the material, or hard-to-access areas may require the use of special delay lines.

*Exact range depends on material sound velocity, transducer frequency, part geometry, and surface condition.
High-Temperature Delay Lines
High-temperature delay lines function as a protective buffer between the hot surface of the test piece and the transducer's crystal. At elevated temperatures, intermittent contact is recommended to protect the transducer from thermal damage.

*这些探头只能与高穿透软件选项一起使用。
**需使用弹簧加载支架。
Microscan探头经常与测厚仪、探伤仪及其它超声仪器配合使用，完成多种检测应用。
Microscan探头的工件编号表明了其所使用的接口类型：
RM = 直角Microdot
SM = 平直Microdot
RB = 直角BNC
SB = 平直BNC
SU = 平直UHF
在选择探头时，请查看下面的探头列表，或查阅随您所购买仪器附送的指导手册中的探头频率范围。
Microscan接触式探头的一个优点是其通用性；一个单一探头可以覆盖很多工程材料宽泛的厚度范围。接触式探头装有的WC-5防磨板，具有更好的耐用性能和更长的使用寿命。
