Embodiment Construction

[0039] figure 1 The ultrasonic particle measurement system 1 of the present invention is schematically shown. The ultrasonic transducer 2 , which transmits and / or receives acoustic signals via a coupling element, is fastened in the measuring tube 8 at an angle to the measuring tube axis. This is the so-called inline measurement system. The signal path along which the ultrasound signal propagates is modeled here through the center axis of the ultrasound transducer 2 .

[0040] The ultrasound transducer 2 comprises an acoustic lens 10 which focuses the ultrasound signal in the measuring tube 8 . The focal point of the acoustic lens 10 of the ultrasound transducer 2 is located in the volume 11 for particle measurement. This volume 11 results from the focusing of the lens. It is here rotationally symmetrical about the signal path 9 and is drawn substantially elliptical in the section shown. In this volume, particles are recorded by the reflection of the acoustic signal on the...

Abstract

The invention relates to an ultrasonic particle measurement system (1) comprising: an ultrasonic transducer (2) having at least one ultrasonic transducer element (4) and at least one coupling element (5), wherein, during operation, via the coupling element ( 5) Acoustic signals can be transmitted and received via the ultrasonic transducer element (4). The coupling element (5) is designed as an acoustic lens, and the ultrasonic particle measurement system (1) comprises an evaluation unit adapted to analyze the amplitude of the reflected signal of the acoustic signal reflected by the particle towards the ultrasonic transducer (2), wherein, The evaluation unit is used to count the number of reflected signal amplitudes which are greater than a predetermined threshold in a predetermined time interval.

Description

technical field [0001] The invention relates to an ultrasonic particle measurement system comprising an ultrasonic transducer having at least one ultrasonic transducer element and at least one coupling element, wherein during operation the ultrasonic transducer element is accessible via the coupling element Acoustic signals are transmitted and can be received, wherein the ultrasonic transducer is arranged in the measuring tube. Background technique [0002] Ultrasonic transducers generally consist of an electromechanical transducer element, for example a piezoelectric element, also referred to simply as piezoelectric, and a coupling layer, also known as a coupling wedge or, less often, an introduction element . The coupling layer is in this case mostly produced from a synthetic material, while the piezo element in industrial process measurement technology usually consists of a piezoceramic. Ultrasonic waves are generated in the piezoelectric element and are guided via the ...
