Elcometer Home Page

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
