Abstract: The piezoelectric vortex sensing element (3, 3′, 3″, 3+) of this vortex flow sensor (1) can be assembled from individual components in a simple manner; if its piezoelectric element (34, 34′, 34″, 34*, 34+, 34++) should be faulty, it can be easily replaced. Also, the vortex sensing element can be made largely insensitive to vibrations acting from outside. The vortex flow sensor (1) serves to measure the flow velocity and/or the volumetric flow rate of a fluid flowing through a measuring tube (2). A bluff body (4) generating Kármán vortices is disposed along a diameter of the measuring tube and fixed to the measuring tube at at least one fixing point (41). The vortex sensing element responds to vortex-induced pressure fluctuations and either is installed in a wall (22) of the measuring tube down-stream of the bluff body in a tight manner or extends into a main bore (46) extending through the measuring tube into the bluff body.

Abstract: This vortex flow sensor is to be designed either as vortex sensor with a capacitive vortex sensing element (3, 3') either arranged in the hole of a bluff body (4) or inserted into a wall opening of a measuring tube (2, 2') downstream of the bluff body. Both vortex sensing elements being of largely identical construction and being capable of being produced as an independent component in the manner of a module. The wall sensor (3) and the bluff body sensor (3') has a diaphragm (33, 33') sealing off the hole and the wall opening. A flexurally stiff thin sensor vane (31) or sensor sleeve (51) and a sleeve-shaped electrode arrangement (34, 34') with at least one electrode (341, 341') are attached to the diaphragm on opposite sides. A housing cap (32, 32') surrounds the electrode arrangement and the diaphragm, is fixed on the measuring tube and contains a second electrode arrangement (35, 35') with at least one counter-electrode (351, 352; 351', 352').

Abstract: An expansion bolt assembly for use in boreholes with an annular undercut adjacent the base of the boreholes includes an axially elongated anchor bolt, a support sleeve laterally enclosing the anchor bolt with annular segments formed on the support sleeve, and an expansion sleeve to be inserted between the anchor bolt and the support sleeve. The annular segments are displaced radially outwardly by the expansion sleeve into the undercut in the borehole. The annular segments extend radially outwardly from the outside surface of the support sleeve. During the expansion procedure the outer surface of the support sleeve is pressed against the surface of the borehole.
