Abstract

The wave guide (1) in the form of a bar or wire is made of thin, coiled foil (2), with discs (4) on the end-side ends and which form a homogeneous material-join (5) with the coiled foil. The wave guide can consist of a thin-walled bundle of concentric tubes.

Description

Stab- oder drahtförmige Wellenleiter werden zur Übertragung von Ultraschallsignalen zwischen einem Wandler (Sender oder Empfänger) und einem Medium in einem technologischen Prozess z. B. bei der Messung der Materialdicke oder des Durchflusses angewendet.Rod or wire shaped waveguides are used to transmit ultrasonic signals between one Converter (transmitter or receiver) and a medium in a technological process such. B. at the Measurement of material thickness or flow rate applied.

Bei der Übertragung Ultraschallsignale mit einem üblichen massiven, draht- oder stabförmigen Wellenleiter entstehen durch Dispersion von Schallenergie mit wachsender Frequenz zunehmende Übertragungsverluste. Diese Verluste sind außerdem dem Durchmesser des Wellenleiters proportional. Die Übertragung hochfrequenter Ultraschallsignale mit hinreichend niedrige Verluste erfordert deshalb sehr kleine Durchmesser des Wellenleiters-Durchmesser, die für eine effektive Ankopplung an ein Medium oder an Elemente der Ultraschalltechnik in der Regel viel zu klein sind.When transmitting ultrasonic signals with a conventional solid, wire or rod-shaped Waveguides are created by dispersing sound energy with increasing frequency Transmission losses. These losses are also proportional to the diameter of the waveguide. The transmission of high-frequency ultrasound signals with sufficiently low losses therefore requires very small diameter of the waveguide diameter, which is required for an effective coupling to a Medium or elements of ultrasound technology are usually much too small.

Aufgabe der Erfindung ist ein Wellenleiter, der mit hinreichend großen Durchmesser für eine effektive Ankopplung eine verlustarme Übertragung hochfrequenter Ultraschallsignale ermöglicht.The object of the invention is a waveguide with a sufficiently large diameter for an effective Coupling enables low-loss transmission of high-frequency ultrasound signals.

Diese Aufgabe wird durch einen Wellenleiter nach Anspruch 1 oder 2 gelöst.This object is achieved by a waveguide according to claim 1 or 2.

Es wurde gefunden, dass die Übertragungsverluste hochfrequenter Ultraschallsignale in einem Wellenleiter aus dünnwandiger Folie oder dünnwandigen Rohr ähnlich gering sind wie bei einem dünnen Draht. Aber durch die Wicklung der Folie oder durch die konzentrische Bündelung von Rohren wird ein größerer Übertragungsquerschnitt, damit eine bessere Ankoppelung mit höherer Energieübertragung erreicht.It has been found that the transmission losses of high-frequency ultrasonic signals in one Waveguides made of thin-walled film or thin-walled tube are as small as a thin one Wire. But by wrapping the film or concentrically bundling pipes, one becomes Larger transmission cross-section, so better coupling with higher energy transmission reached.
