Abstract
Sensitive elements of current sensors on surface acoustic waves based on magnetically sensitive FeNi films have been studied. It is shown that the use of such films provides a sufficiently high sensitivity to a magnetic field and allows refusing magnetic cores, which significantly reduces the weight and size parameters of the sensor and facilitates its installation on a conductive bus. The design of the current sensor with a FeNi film in the acoustic channel and the layout of the sensor on the conductive bus are shown. The influence of the location of the antennas on the sensor readings have been studied. It is shown that when the distance between the antennas changes, the resonant frequencies of the resonator surfactant do not shift. It is revealed that the ratio of the peak areas of primary and secondary reflections on the pulse responses of surfactant sensors does not depend on the distance between the sensor and reader antennas. This will eliminate the reference channel, which will simplify the design of the surfactant sensor.
