Published Date: 07/21/2016

Description

Ratiometricity is a common approach for measuring analog-sensor signals for the purpose of conditioning and standardizing the signal for proper operation with an industrial control system. In the context of linear-variable differential-transformer (LVDT) signal conditioning, ratiometric measurement has a specific meaning. In this article, ratiometric measurement is described in general and also in the context of LVDT-sensor signal conditioning in three different stages of the signal chain.
