Embodiment Construction

[0061]figure 1 An example of a transducer 10 for non-invasive measurement is shown. The transducer includes at least one first piezoelectric element 20, a second piezoelectric element 30, and a base material 40. The matrix material is configured to mount wall 50 that is configured to accommodate the liquid.

[0062]The term "container" is hereby used in a broad sense, not limited to the closed reservoir, but also a reservoir at least partially open, and also includes a medium configured to accommodate or direct any type of medium (such as all kinds. Liquid, liquefied solid or gas) tube or pipeline or pipeline.

[0063]The base material includes a planar portion 60 and a angular portion 70. The angular portion includes a plurality of outer 80. In the exemplary embodiment shown here, the plurality of outer surface 90 of the angular portion are connected to the first surface 100 of the (or coupled) the planar portion. Typically, the angular portion and the planar portion physically form the ...

Abstract

The present invention relates to a transducer (10) for non-invasive measurement. The transducer comprises at least one first piezoelectric element (20), a second piezoelectric element (30), and a base material (40). The base material is configured to be mounted to a wall (50) of a vessel configured to contain a liquid. The base material comprises a planar portion (60) and an angular shaped portion (70). The angular shaped portion comprises a plurality of outer faces (80). A first face (90) of the plurality of outer faces of the angular shaped portion is connected to a first face (100) of the planar portion. A second face (110) of the planar portion opposite to the first face of the planar portion is configured to be mounted to the wall of the vessel. At least one second face (120) of the plurality of outer faces of the angular shaped portion is angled to the first face of the plurality of outer faces of the angular shaped portion at an angle less than an angle of 90 degrees internal to the base material. The at least one first piezoelectric element is mounted to at least one of the at least one second face of the plurality of outer faces of the angular shaped portion. The second piezoelectric element is mounted to the first face of the planar portion of the base material at a position adjacent to the angular shaped portion of the base material.

Description

Technical field[0001]The present invention relates to a transducer (in particular, ultrasonic transducer) and associated uncovalent measurement methods for non-invasive measurement, and is used for non-invasive transducer systems and associated unconscious measurement methods.Background technique[0002]Industrial applications including non-destructive testing, non-invasive flow, or levels, using acoustic technologies require a special type of ultrasonic transducer in the surrounding medium in a large angular range. In particular, for liquid level measurement applications, the sensor must be capable of encompassing a span of a span in the range between 0 and 70 ° in a normal direction of the tank surface. These requirements cannot be satisfied by using a single piezoelectric element. Thus, in order to achieve a sufficiently large radiation angular range, a piezoelectric phased array driven by a phase shift signal is typically employed - see No. 4,692654a, WO2016134005A1, and EP0264991...
