Asymmetric wire gap sensor design and optimization

In order to meet the industrial production in steel demand detection, a new sensor model is prop-osed which can simply and directly detect the strip steel gap. The performance of the sensor can be optimized by using ANSYS to study the magnetic line distribution around the wire in the alternating magnetic field, to show the output current changes at both ends of the coil in the process of moving the probe of the sensor to analyse the influences on the performance of the sensor from different wire gaps in the current amplitude of the peak gap spacing .Experiments show that: the sensor''s high sensitivity, good to meet the requirements of a wide range of applications at the same time as the design of the sensor.
