Measuring Rp of an L-C Sensor for Inductive Sensing

Texas Instruments

Published Date: 10/01/2015

Description

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
