Fiber optic differential pressure sensor
A differential pressure sensor system is provided which is an improvement over prior sensor systems. The provided sensor system can be used to determine parameters of fluid flowing through a tubular string in a well.Basically, this system has an optical fiber extending in a wall having a first side and a second side, each of the sides being exposed to pressure in the flow passage.An optical medium is attached to one side of the wall, so that the optical medium detects hoop strain in that side ....etc

A fiber-optic sensor system consists of a fiber-optic cable connected to a remote sensor, or amplifier (see Figure 1).

Figure 1. In a fiber-optic sensing system, the emitter and the receiver share a single housing. The fiber-optic cable that is connected to the ampli ....etc

Abstract

This curriculum module is part of a set of four curriculum modules. The curriculum module can be adapted to be used alone, or used as part of the set. In this project, students learn about the importance of monitoring stresses on bridges and other civil infrastructure, and about how public safety can be improved by using wireless sensor networks for continuous structural health monitoring. This curriculum module, the first in the set, introduces topics in sensor read-out electronics and data co ....etc

Structural Health Monitoring Using Wireless Sensor Networks



INTRODUCTION

Wireless sensor network enables low-cost sensing of envi-
ronment. Many applications using wireless sensor networks
have low duty cycle and low power consumption. However
the ability of wireless sensor networks can be extended in re-
verse way. Enhanced TinyOS, and new components opened
possibility for more aggressive applications. Structure mon-
itoring is one example of such applications. To monitor ....etc
