Tube, Strip and Plate (EMAT)

The temate® TG-IL is an EMAT solution designed for measuring thickness of metallic materials with non-contact probes in harsh production environments.


  • Non-contact EMAT technique.
  • Probes for continuous measurement of materials up to 750ºC.
  • No-wear sensors that do not touch the material inspected.
  • Great accuracy (+/-2.5µm) and lateral resolution (3mm).
  • Sensor arrays and touch probes for continuous and spot measurements.
  • 100% tube coverage option using proprietary encircling ring technology.
  • Automatic calculation of eccentricity and ovality.
  • Thickness measurement on internally tapered tubes.
  • Applicable to tubes (steel, ductile iron), aluminum plates (reversing mills), and many other high-temperature and high-speed applications in harsh environments.


  • Technique:
    • Non-contact Electro Magnetic Acoustic Transducer (EMAT)
  • Materials Inspected:
    • Ferromagnetic and non-ferromagnetic metals, including carbon steel, stainless steel, aluminum, copper and brass.
    • Minimum thickness : 1mm (0.039”) contact Innerspec for thinner material
    • Surface temperature: from -30ºC (-22ºF) to 750ºC (1,382ºF)
  • Measurement Accuracy and Lateral Resolution:
    • Accuracy: (+/-2.5µm).
    • Lateral Resolution (3mm).
  • Sensor Head Assembly:
    • Magnetic element and EMAT coil in a protective casing.
    • Sensors for high-temperature applications may incorporate air and/or water cooling depending on temperature and exposure time.
    • Designed for easy attachment to different mountings, and can incorporate air bearings or other systems to maintain adequate lift-off.
    • Automatic temperature compensation for high-temperature applications.
  • Instrumentation:
    • IP54 industrial enclosure can be located up to 2m from point of inspection.
    • Different enclosures can handle from 1 to 8 channels simultaneously.
    • 1 Channel Enclosure. Dimensions: 252mm L x 169mm W x 57mm T. Weight: 1.5Kg
    • Accessible by any device connected to the instrument’s IP address via WiFi or Ethernet.
