振動型トランスデューサ
Document Type and Number:
Japanese Patent JP3977330
Kind Code:
B2
Abstract:
The invention relates to a measuring sensor with a housing that is formed by a support frame (6) for holding a fluid-containing measuring tube (4) and a housing cap (7) for accommodating at least one bent tubular segment (41) of the measuring tube (4) that vibrates when the measuring sensor is operated. The housing cap (7) encloses a trough-shaped cap segment (71) having a circarc segment rim (71a) with a predetermined radius R and a segment rim (71b) that is formed substantially identical to the segment rim (71a). The cap segment (71) has a circarc cross-section with a radius r that is smaller than the radius R of the segment rim (71a). The housing cap (7) further comprises a substantially planar second cap segment (72) that is linked with the segment rim (71a) of the first cap segment (71) via a circarc segment rim (72a), and a cap segment (73) that is substantially mirror-symmetric to the cap segment (72) and that is linked with the segment rim (71b) of the cap segment (71) via a circarc segment rim (73a). The cap segments (72, 73) have a respective substantially higher flexural strength than the cap segment (71). The use of the housing cap (7) allows the housing of the measuring sensor (1) to be produced at low costs and with an as high flexural strength as possible.
