  • Abstract
    The design of a low-cost, linear position sensor, based on the transmission of ultrasonic signals in a magnetostrictive delay line is presented. The paper analyzes the sensor principle, parameters to be optimized, conditioning circuits as well as sensor characterization, comparing the results with commercial sensors.
