Vitesse des ultrasons dans un matériau solide

Principe de l'expérience:

Détermination de la vitesse du son de l'acrylique par technique de temps de vol (time of flight) avec un échoscope à ultrasons. Les mesures par méthode de réflexion sont effectuées sur trois cylindres ...

Echographie ultrasonique - SCAN A

Principe de l'expérience

Une onde ultrasonique tranversant un échantillon solide sera renvoyée par des discontinuités (défauts, fissures). La relation entre temps de vol et vitesse du son de l'onde renvoyée permet de calculer la distance entre la ...

Echographie ultrasonique - SCAN B

Principe de l'expérience:

Introduction aux aspects fondamentaux des techniques du B-scan ultrasonique en utilisant un échoscope sur un objet de test simple. Discussion de la qualité d'image en termes de résolution spatiale, focalisation ultrasonique, aberrations ...

Détection de discontinuités

Principle
The experiment demonstrates the application and performance of various non-destructive test methods with the aid of ultrasound. A test object with different types of discontinuities is used to perform various detection methods. First, the test object is scanned in order to determine ...

Tomodensimètre à ultrasons assisté par PC

Principle

This experiment explains the fundamental principles of image formation with a CT algorithm. A test object is used to create an attenuation tomogram and a time-of-flight tomogram followed by a discussion of the respective differences.

Benefits

• Ideal system for education: ...

Water quality - contamination avec heavy métals

Principle

Heavy-metal ions may be carried into surface or ground water from mining fields or via the waste water of galvanic or similar production sites. They block the effect of enzymes so that the processes in the metabolism of the organisms that are controlled by these enzymes may ...

Thermal insulation avec measureAPP

A quick loss of heat is sometimes not wanted. What can be done to keep the temperature in a vessel
constant? Students are measuring the cooling of hot water in two different environments.

Thermal insulation avec SMARTsense

Heating of water

Principle

How depends the time required to heat up water on the amount of water when a defined heating source is available? The students are heating up various amounts of water with an electric heating coil and measure the time dependence of the ...

Heating of water with SMARTsense

Heating of various liquids avec measureAPP

Principle

Do different liquids heat up to the same extent when subject to the same heating? The students are heating 100 g and 100 ml of water and of glycerol with an electric heating coil and measure the temperature in dependence on
