Abstract
The invention relates to a measurement sensor for a vortex flowmeter having a damming member, a scanning element disposed downstream of the damming member, and an electromechanical transducer associated with the scanning element and embedded therein, wherein a deformable compensating layer is provided at least in portions between the electromechanical transducer and the scanning element.
Claims11
A high-temperature-tolerant measurement sensor for a vortex flowmeter having
- a damming member (2),
- a scanning element (6) disposed downstream of the damming member (2),
- a piezoelectric transducer (1) associated with the scanning element (6) and embedded therein, and
- a deformable compensating;
- layer (17) provided, at least in portions, between the piezoelectric transducer and the scanning element,
- wherein, in order to provide temperature resistance up to at least about 400.degree. C., the compensating layer is a glass silk laminate.

A high-temperature-tolerant measurement sensor for a vortex flowmeter having
- a damming member (2),
- a scanning element (6) disposed downstream of the damming member (2),
- a piezoelectric transducer (16) mounted inside the scanning element (6), and
- wherein, in order to compensate for differing coefficients of thermal expansion and to provide resistance to temperature shock,
- a glass silk laminate (17) is provided, at least in portions, between the piezoelectric transducer (16) and the scanning element (6), to serve as a deformable compensating layer.
