Design of Pressure Measuring Cells Using the Unified Material Law

P. Aguirre[1], F. Figueroa[1]
[1]Sensor Technik Wiedemann GmbH, Kaufbeuren, Bayern, Germany

Pressure Sensors are widely used in the automotive industry. Their main use is the dynamic monitoring of pressure inside combustion engines. To achieve a good signal accuracy, the design of pressure sensors can be improved with FEM calculations of stress and strains on the measuring cell ... En savoir plus

Finite Element Modeling a Redox-Enzyme-Based Electrochemical Biosensor

Y. Huang[1], and A. Mason[1]
[1]Electrical and Computer Engineering, Michigan State University, East Lansing, Michigan, USA

This paper describes the modeling of an electrochemical biosensor embedded in a microfluidic channel to determine the concentration of a target biomolecule. The total amount of analyte in the sample can be calculated by integrating the analyte concentration over the duration of the peak ... En savoir plus

Simulation of Moisture Ingression in Microelectronics Packages to Correlate Test and Field Conditions

In electric distribution network, current and voltage measurement for metering, monitoring, and protection & control applications is done via instrument transformers (current and voltage transformers). These measurement devices are deployed during the construction phase of the ... En savoir plus

Simulation Driven Design of Blood Warmer

Rajesh K. [1], Sivakumar A [1],
[1] HCL Technologies, Chennai, Tamil Nadu, India

Blood Warmer is a movable instrument intended to deliver peripheral warmth to the arterial piping so as to keep the blood under warm conditions or liquid passing by throughout transfusion. The instrument is used to keep the blood or fluids under desired warm states before to transfusion ... En savoir plus

Development of Eddy Current Probe using FEM for Matte Level Detection in Pyrometallurgical Furnaces

A. Saleem [1], P. R. Underhill [1], D. Chataway [2], T. Gerritsen [2], A. Sadri [2], T. W. Krause [1],
[1] Department of Physics and Space Science, Royal Military College of Canada, Kingston, ON, Canada
[2] Hatch Ltd., Mississauga, ON, Canada

Pyrometallurgical furnaces are used to produce metals such as copper, nickel and platinum by the smelting process. During smelting, the undesired material components are separated from the desired metal resulting in the formation of a slag and matte/metal phase. The slag phase ... En savoir plus
