保護(hù)面探頭是一種單晶縱波接觸式探頭，可與延遲塊、保護(hù)膜或防磨保護(hù)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
