奧林巴斯VHTD-5-X（X=延遲塊長度分別是13mm/25mm/38mm)高溫延遲塊

保護面探頭是一種單晶縱波接觸式探頭，可與延遲線、保護膜或防磨保護蓋一起使用。

Advantages:

• Provides versatility by offering removable delay line, protective wear cap, and protective membrane
• When the transducer is used alone (without any of the options), the epoxy wear face provides good acoustic impedance matching into plastics, many composites, and other low impedance materials
• Cases are threaded for easy attachment to the delay line, protective membrane, and wear cap options

Applications:

• Straight beam flaw detection
• Thickness gaging
• High temperature inspections
• Inspection of plates, billets, bars, and forgings

High Temperature Delay Line Options

• Allows for intermittent contact with hot surfaces*
• Improves near surface resolution
• Contouring of delay lines provides better coupling on curved surfaces
• Warm temperature delay lines (WTD) can be used for room temperature applications

*Recommended usage cycle is ten seconds maximum contact followed by one minute of air cooling. However, the transducer itself should not be heated above 122°F (50°C).

X = standard delay line lengths, available in 1/2" (13 mm), 1" (25 mm), 1-1/2" (38 mm). Specify at time of ordering.

Note: For the delay lines above, a room temperature material longitudinal wave velocity of 0.100 in/μsec ±0.005 in/μsec may be used as an approximation for basic calculations. This value should not be used for engineering design calculations.

Protective Membrane Option

• Improves coupling on rough or uneven surfaces
• Dry couple to smooth, clean surfaces

*Available in 36" x 36" x 1/32" sheets. Order part number NPD-665-3101.

? Kit includes 12 Membranes, 1 ring, C-2 couplant

Protective Wear Cap Option

? The nylon wear cap provides an economical solution in applications requiring scanning or scrubbing of rough surfaces
