Record Type: concept
time-domain reflectometry (time-domain reflectometry) (measuring, analysis and testing techniques, ... Processes and Techniques (hierarchy name))

 

Note: Measurement method originally used to to detect properties of electrical transmission lines; and more recently as a technique to determine dielectric water content in stone structures and in soil. It involves applying stepped voltage in pulses and observing reflected waveforms which reflect discontinuities by amplitude. The distance to the reflecting impedances is measured by the time it takes a pulse to return.

Additional Notes:
Dutch ..... Meetmethode die oorspronkelijk bedoeld was om eigenschappen van elektrische transmissielijnen te detecteren. Later werd met deze techniek het di├źlektrisch watergehalte in stenen bouwconstructies en in de bodem bepaald. Elektrische spanning wordt in stappen door middel van pulsen verhoogd en gereflecteerde golfvormen worden geobserveerd. In de amplitude van golfvormen worden de discontinu├»teiten weergegeven. De afstand tot de reflecterende obstakels wordt gemeten op basis van de tijd die het duurt totdat een puls is teruggekeerd.
