[4] COMSOL Multiphysics GmbH, Göttingen, Germany

Today, 90 percent of automation sensors are binary proximity detectors. Besides capacitive and optical types, inductive proximity sensors are essential for industrial applications. Compared to their mechanical counterparts, they offer almost ideal properties as contact-free and wear-free ... En savoir plus

Simplified Finite Element Simulation of a SAW Hydrogen Sensor using COMSOL Multiphysics

N. Krishnan[1], H. Nemade[1,2], and R. Paily[2]
[1]Centre for Nanotechnology, Indian Institute of Technology Guwahati, Assam, India
[2]Department of Electronics and Communication Engineering, Indian Institute of Technology, Assam, India

In this paper, we discuss a simplified finite element method simulation of surface acoustic wave (SAW) delay line hydrogen sensor using COMSOL Multiphysics. A delay line SAW sensor consists of a transmitting interdigital transducer (IDT) and a receiving IDT separated by a few ... En savoir plus

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
