A protected face transducer is a single element longitudinal wave contact transducer that can be used with either a delay line, protective membrane, or protective wear cap.
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
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.
