NDT1-220K Ultrasonic Transducer SPECIFICATIONS Description Model No. Part No. Dual layer 110 m NDT1-220K 1005935-1 FEATURES 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 Low cost ultrasonic transducer Flexible Format 3 MHz nominal center frequency Various housings available High Bandwidth; Low Q Performance Low Impedance 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 (airbacked, 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.
