  • Acoustic / Ultrasonic Transducers
    . Underwater acoustic transducers have an operational range, but are usually designed to operate at their resonance frequency to maximize output power. They are most typically single frequency transmitters, but they may contain multiple transmitters and receivers for different frequencies.

  • Case Study: Bonding Integrity in Bimetallic Steel Tubing
    A number of samples were provided in 4 groups for evaluation of the interlayer bond integrity of stainless steel- tantalum-stainless steel tubing. These samples were examined with two types of RMEMATs (resonance mode electromagnetic acoustic transducers) each of several configurations; toroidal
  • Case Study: Surface Defect Analysis of Bearing Grade Hot Rolled Steel
    acoustic transducers (RM-EMAT) were fabricated for this test. The transducer width is 1.3" with an axial inspection window of about .75". The first transducer was a 1.970" ID was a N:29 or 29 wavelength transducer that produced a resonant frequency of approximately 547 kHz. This transducer did not provide
  • Case Study: Case Depth Analysis of Induction Hardened Steel
    Three short samples of 61.1341 mm diameter induction hardened steel were tested utilizing the ARIS (Acoustic Resonance Inspection System) and three different iterations of a toroidal resonance mode electromagnetic acoustic transducer (RM-EMAT). These samples were marked S, N and D representing

  • Case Study: Surface Defect Analysis of Copper Tubing
    Tests were conducted on Copper tubing of various diameters and wall thickness. These samples were tested in standard resonance mode EMAT's (electromagnetic acoustic transducers) configured for aluminum and steel rod. A rotary encoder input was utilized to generate the data plots of resonant
  • Do You Need To Measure Brake Noise?
    and was repeated continually over a period of many days. The P8000 hardware can take data simultaneously from a wide range of transducers as well as CAN-bus/GPS inputs. This allowed vehicle data to be easily combined with measured vibration and acoustic data and presented to the user in a coherent
