EMAT Ultrasonic Thickness Gage

Product Details:


Product Description

As an Authorized dealer we are engaged in providingthe broad assortment of wide gamut of NDT Instruments

This is a portable electromagnetic ultrasonic abbr as  EMAT thickness gauge to be used without couplant or direct contact on materials ofmetal or magnetism based on electromagneticacoustic transduction

The main difference of this technology is that the ultrasonic waveis generated directly in the tested object

The principle of the action of EMA transducers is based on theexcitation and reception of ultrasonic waves by induction on the surface of anelectrically conductive object of alternating and constant magnetic fields TheEMAT inductor through which a highfrequency current pulse flows creates aneddy current in the surface layer of the metal As a result of the combinedeffect of the eddy current and the polarizing field Lorentz forces arisewhich ensure the excitation of ultrasonic oscillations of the correspondingtype Depending on the design parameters of the inductor and the orientation ofthe polarizing field shear SH waves of radial or linear polarization an ovalor rectangular inductor are excited during the monitoring process

Due to naffectedness by surface of the object it can be appliedto those with rust oxide layer or coating like oil pipe or aircraft partssaving the effort to clear them off Angle shift of the probe has no effect onthe result with the available gauge range 2300mm and the precision up to 001mmThis instrument can also work on hot objects such as forged pieces radiatorsand heat exchangers assisted by necessary kittings supplied by the manufacturerTherere optional functionalities like BScan RS485 BUS networking GPRSwireless communicating and SMS for the users to realize their modern dreams onNDT instruments

Areas of Application

  • Metallurgy
  • Aerospace
  • Pressure Vessel
  • Thermal Circulation
  • Shipbuilding
  • Machinery
  • Construction
  • Power Generation
  • Nuclear Power
  • Refrigeration


  • To gauge thickness of metal ormagnetic objects with rough surface that might cause poor coupling for pureultrasonic transduction
  • To get precise thickness dataof metal part beneath coated layer, such as rust, oxide or artificial coatingmaterial. Oil pipes, aircraft parts
  • To work under special situation that theres air gap or some obstacle stuck between the transducerand the metal object.
  • As an solution to thickness gauging on objects of high temperature without loss of data and damage to thetools (transducers & instrument) and the operator forged pieces, radiators, heat exchangers (up to 300 at-and-away: up to 600)
  • to make the job of gauging go on under severely cold weather (lowest to -40)

EMAT Transducer

The is kitted with an EMAT probe (2MHZ but can be customized to different specification)that can induce eddy current as to generate ultrasonic wave on the surface of ametal or magnetic object by permanent magnet and electrified coil. Strongconstitution by solid casing and temp-insensitive element enables this transducerto function over harsh conditions like coarse-textured interface and extremeclimate (kitted with heat-proof probe cable).
