Use of COMSOL® AC/DC Module to Model a EM Sensor Deployed to Monitor Steel Transformation

J. Shen [1], W. Jacobs [1], L. Zhou [1], P. Hunt [2], C. Davis [1],
[1] Advanced Steel Research Centre, WMG, University of Warwick, Coventry, UK
[2] Primetals Technology Limited, Christchurch, UK

Real-time microstructure monitoring is important during the cooling process for hot-rolled strip steel production, as the microstructure formed determines the mechanical properties required by customers. The materials magnetic and electric properties, relative permeability and ... En savoir plus

A FEM Study of Displacement Sensor Based on Magnetostrictive/Piezoelectric Composite Material

Qingwei Liu [1], Hangjie Mo [1]
[1] Shanghai Jiao Tong University, Shanghai, China

This paper studies the application of laminate magnetoelectric (ME) material in displacement sensor. We studied the L-L block composite thanks to designed structure by coupling displacement signal with the displacement potential of ME composite. A nonlinear approximation is adapted to ...

Modeling defect detection in deep-seated tendons of prestressed concrete using magnetic flux leakage

S. Thieltges¹, C. Zimmer¹, D. Meiser¹, L. Lauck¹, S. Youssef², K. Szielasko¹
¹Fraunhofer Institute for Nondestructive Testing IZFP, Saarbrücken, Germany
²Institut Dr. Foerster GmbH & Co. KG, Reutlingen, Germany

The integrity and safety of reinforced concrete structures are of paramount importance in civil engineering. Detection of flaws in prestressed tendons, especially those buried at critical depths greater than 20 cm, presents a significant challenge. Magnetic flux leakage (MFL) is a non ... En savoir plus

Simulation of an ECT Sensor to Inspect the Reinforcement of Concrete Structures

N. P. de Alcantara Jr. [1], L. Gonçalves Jr. [1],
[1] São Paulo State University - Unesp, Bauru, SP, Brazil

The paper describes the use of COMSOL Multiphysics to simulate an ECT (Eddy Current Testing) sensor, designed to inspect the elements of the reinforcement of concrete structures. The paper describes the steps for the COMSOL simulation, and analyze the results for three configurations ... En savoir plus

Design and Analysis of CO2 Sensor using COMSOL Multiphysics® Software

S. B. Umbarkar[1], G. Y. Rajput[1], R. Vasappanavara[1],
[1] Department of Electronics Engineering, RAIT, Navi Mumbai, Maharashtra, India.

In this paper, a carbon dioxide sensor is introduced. At present many CO2 sensors are available, but they all required power in the order of few watts, therefore they are not suitable for long term unattended operation. This paper gives the brief description of CO2 sensor modeling using ... En savoir plus

CSRR-Based Microwave Sensor for Measurement of Blood Creatinine Concentration Levels

Z. Ramsaroop [1], S. Rocke [1], N. Gayapersad [1], J. Persad [1],
[1] Department of Electrical and Computer Engineering, The University of the West Indies, St. Augustine Campus, Trinidad and Tobago

Non-communicable diseases (NCDs) have globally become a prevalent problem, accounting for more than 60% of the mortality worldwide. NCDs impose socioeconomic consequences to low-income countries as 80% of NCD deaths occur in such countries [1, 2]. The World Health Organization has ... En savoir plus

RFID-Enabled Temperature Sensor

I.M. Abdel-Motaleb[1], K. Allen [1]
[1]Department of Electrical Engineering, Northern Illinois University, DeKalb, IL, USA

The design of a RFID-enabled temperature sensor is described in this paper. In this sensor, a change in temperature causes structural beams to bend, which results in a proportional displacement of the plates of the capacitor. Plates\' displacement results, in turn, in changing the value ... En savoir plus

Simulation of DC Current Sensor

K. Suresh, B.V.M.P.S. Kumar, U.V. Kumar, M. Umapathy, and G. Uma
National Institute of Technology Tiruchirapalli, Tamil Nadu, India

A proximity DC current sensor using of a piezo sensed and actuated cantilever beam with a permanent magnet mounted at its free end is designed and simulated in COMSOL Multiphysics. The change in resonant frequency of cantilever is a measure of the current through the wire. The sensor is ... En savoir plus
