Elcometer have a wide range of transducers to meet your requirements, including: A Range of Frequencies and Sizes Straight and Right Angle Transducers available as Potted or Microdot Transducers — Potted Transducers: Transducer cable is fixed to the transducer head — Microdot Transducers: Plug in cables allowing transducer head or cable to be replaced quickly and easily. High Temperature Transducers: Temperature up to 340ºC (650ºF) When selecting a transducer, it is important to choose one which will best meet your application, taking into consideration: The Measurement Range The Type of Material to be Tested The Design of the Transducer Probe SPEED OF SOUND THROUGH MATERIALS Elcometer Ultrasonic Thickness Gauges can be programmed by the user to the appropriate material in two ways: Known standard of the same material - set the calibration to the thickness The frequency calibration - set the frequency to the appropriate material using the Velocity Chart below
