Ultrasonic Transducer Dual Layer

The NDT1-220K element offers outstanding ultrasonic transducer performance in a low-cost, flexible format for general-purpose use. It has a 3 MHz nominal center frequency, with extremely low Q-factor of 1.3 (air backed, into PMMA). Electrical impedance is well matched to conventional NDT instrumentation (pulsar/receivers). Unit-to-unit repeatability is very good. The transducer is robust, and conforms perfectly to cylindrical surfaces such as pipe or tank walls. Epoxies, transfer adhesives, or even double-coated tapes may be used as bonding agents.

• High Bandwidth, Low Q Performance
• Excellent Acoustic Match to Liquids, Polymers
• Low Electrical Impedance (30 to 100 ohms typ)
• Lightweight, Robust, Flexible Design
• Conforms to Flat or Curved Surfaces
• Low Cost, Disposable Transducers
