Three Dimensional Numerical Analysis of an Eddy Current Flow Meter

AVIJIT CHAKRABORTY¹, Prashant Sharma¹, S. K. Dash¹, B. Babu¹, B. K. Sreedhar¹
¹Indira Gandhi Centre for Atomic Research, Kalpakkam, Tamil Nadu

Liquid Metal Fast Breeder Reactor (LMFBR) employs molten sodium as coolant due to its suitable neutronic and thermal properties. Measurement of coolant flow rate is a very important factor both from operational and safety aspects of a fast reactor. Good electrical conductivity of liquid ... 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 ...

[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

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

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

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
