延遲塊探頭

可更換延遲塊探頭是一種單晶接觸式探頭，專門與可更換的延遲塊一起使用。

優(yōu)勢(shì)

•    強(qiáng)阻尼探頭加上延遲塊可以提供的近場(chǎng)分辨率。

•    較高的探頭頻率提高了分辨率。

•    直接接觸法可提高測(cè)量薄材料及發(fā)現(xiàn)細(xì)小缺陷的能力。

•    具有外形吻合性能，適用于曲面工件。

應(yīng)用

•    測(cè)厚。

•    垂直聲束缺陷探測(cè)。

•    對(duì)接觸區(qū)域有限的工件進(jìn)行檢測(cè)。

可更換延遲塊探頭

•    每個(gè)探頭的配置都帶有一個(gè)標(biāo)準(zhǔn)延遲塊和 一個(gè)固定環(huán)。

•    備有高溫延遲塊和干耦合延遲塊。

•    探頭及延遲塊端部之間需要耦合劑。

Sonopen可更換延遲塊探頭

裝有彈簧的支架SLH-V260-SM*      *僅與V260-SM一起使用。

• 聚焦的可更換延遲塊。

• 直徑極小的特點(diǎn)可以提高在曲面及小缺口上的檢測(cè)性 能。

• 手柄可以方便探頭頭部的定位。

可更換延遲塊探頭選項(xiàng)

* 高溫延遲塊可在溫度高達(dá)175°C（350°F）的情況下使用。

帶有手柄組合件的*延遲塊探頭

這些探頭用于伸到空間極其狹小的區(qū)域進(jìn)行探測(cè)，如： 相距很近的渦輪葉片。探頭可旋轉(zhuǎn)的頭部提高了 其在狹小區(qū)域接觸被測(cè)工件的能力。

可更換延遲線探頭是一款單晶Videoscan探頭，其外殼可連接一條可更換延遲線。

Advantages:

• Heavily damped transducer combined with the use of a delay line provides excellent near surface resolution
• Higher transducer frequency improves resolution
• Improves the ability to measure thin materials or find small flaws while using the direct contact method
• Contouring available to fit curved parts

Applications:

• Precision thickness gaging
• Straight beam flaw detection
• Inspection of parts with limited contact areas
• Replaceable Delay Line Transducers
• Each transducer comes with a standard delay line and retaining ring
• High temperature and dry couple delay lines are available
• Requires couplant between transducer and delay line tip

Delay Line Transducers

Replaceable Delay Line Options 

Sonopen^® Replaceable Delay Line Transducer

• Focused replaceable delay line
• Extremely small tip diameter may improve performance on curved surfaces and small indentations
• Handle for easier positioning of transducer head

Harisonic Pencil Transducers

These high frequency, focused delay line transducers are compatible with any ultrasonic instrument capable of displaying a return echo at depths as low as .010 inches in steel. The typical range is approximay from .010 inches to 0.250 inches in steel. The 0.060 inches circular contact face enables readings to be taken on curved surfaces. Typical applications for these transducers include the inspection of turbine blades, small diameter tubing and concave areas in small parts. Both transducers utilize replaceable delay tips. For best performance, a short cable (such as MB type, 6') should be used. These models, indicated by a part number ending with an "L", incorporate PowerLink™ Technology to assure optimal performance when used with a Sonic ultrasonic instrument. 

The HC-876 ultrasonic transducer operates at high frequency (20 MHz) with a broad bandwidth and small contact surface. Its chief application is thickness measuring of critical components such as jet engine blades. It is fitted with a Microdot connector.

Permanent Delay Line Transducers with Handle Assembly

These transducers are used to reach into areas of limited access such as adjacent turbine blades. The swivel head improves contact in tight areas.
