Reliable testing, even at the highest temperatures

The thermal coils are used in connection with the DEFECTOTHERM sensor system. The water-cooled eddy current differential coils are highly reliable, have a stable signal and long service life. The DEFECTOTHERM coils are used in combination with DEFECTOMAT testing and analysis electronics in continuous processes. The unit's electronics are designed for test speeds of up to 150 m/s, covering all rolling speeds. Test coils with a material diameter of 7 to 65 mm are available.
