Abstract

In many industrial applications different sensors (magnetic, acoustic, optical) have to work under rough conditions. Smart sensors with integrated signal conditioning and processing avoid cable influences and are capable to reject further disturbance influences by signal processing of multi parameter measurements. This article describes a low-power interface for two-wire sensors. The sensor interface was developed for an intelligent eddy current sensor but the concept is not restricted to inductive sensors only.
