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

Features

  • 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 (12.7µm) and good resolution (up to 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.
