Diseño e implementación de un sistema de acondicionamiento para un sensor inclinométrico de precisión, aplicado a la monitorización de deformación volcánica realizada por el Instituto Geofísico de la Escuela Politécnica Nacional

Abstract

This Project is focused on the design and implementation of a monitoring system that quantifies tilt changes on the surface, as a consequence of flank deformation occurring on an active volcano, before, between or after a magmatic intrusion. The monitoring system is comprised of a precision biaxial tilt sensor; analog output signal is conditioned through high linearity and low offset devices. The conditioned signal is submitted to a digitization process by a high resolution analog to digital converter. A similar procedure is done for the temperature signal, delivered by the same sensor, with a mid-resolution ADC. Data contains information about time and date, and is stored on a SD memory device. Additionally RS232 data frame is transmitted by radio from the remote station to IG-EPN headquarters, where it’s recorded on a data base server and displayed on a graphical interface.
