奧林巴斯VHTD-3-X（X=延遲塊長度分別是13mm/25mm/38mm)高溫延遲塊
奧林巴斯VHTD-3-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
Standard Protected Face
-
Comfort Fit sleeves are designed to be easily held and provide steady grip while wearing gloves
-
Standard connector style Right Angle BNC (RB), may be available in Straight BNC (SB)
-
Delay line, protective membrane, and wear cap options sold separately from the transducer

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.
Contact us for details.
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
