  • Measuring Rp of an L-C Sensor for Inductive Sensing
    PDF, 205 Кб, Файл опубликован: 1 окт 2015
    When designing an application using TI’s LDC series of inductive sensors, it is necessary to know the L-C sensor’s equivalent parallel resistance RP at the sensor’s resonant frequency. The RP value changes as the target is moved; the minimum RP occurs when the metal target is closest to the sensor. The maximum RP occurs when the target is at the farthest distance. Accordingly, both values should b
