DIFFERENTIAL INDUCTION SENSOR WITH EXTREME GEOMETRICAL WIDTH OF SCANNING
Josef Blažek – Peter Jozek – Dušan Praslička – Jozef Hudák – Ivan Mikita
The paper presents basic information about special induction sensors for heavy industrial conditions, namely a strong electromagnetic disturbance. As the major parameters are the extreme geometrical width of sensing and precise measurement of the time moment for transition of magnetic markers. For this sensor the gradient differential concept with a core manifesting strong shape anisotropy was selected. The developed sensor is used in practice with great success.
