Simple resistance-to-frequency converter with lead-wire-resistance compensation

Abstract

This article presents a simple technique to realize a resistance-to-frequency converter for single resistive sensor-based remote measurements. The proposed realization method uses commercially available devices to generate output frequency, which is linearly proportional to sensing resistance deviation. Experimental results are shown that not only the good circuit operation but also the effective lead-wire-resistance compensation of the proposed technique can be obtained. © 2013 ICIC International.
