Abstract
A magnetic distance sensor with high sensitivity based on double secondary coil of luxgate has been investigated and discussed in this paper. Fluxga tesensor element is made using conventional methods, based ondouble secondary coildes ign, consists of four primary winding and two secondary windings. Secondary coil is located in the center core and is flanked by the primary coil. Effect of the number of pick - up coil on sensitivity and sensor work area were investigated by making four pick - up coil configurations with a fixed number of winding excitation. Sensor sensitivity increased significantly with increasing the number of pick - up windings while the coil excitation is fixe . Characterization of distance sensor is using permanent magnets as magnetic source and flux meter as calibrators, by changing the position of the magnet on flux meter. We found that the output voltage and sensitivity of sensor is I nversely proportional to the distance range of the sensor. The relative error of sensor measurement to the measurement results of flux meter has a maximum value of 3. 97 %. For distance sensor, we found that the maximum relative error of measurement is 4. 77 %
