Abstract: The invention relates to a component for holding down measuring leads and measuring devices in a groove (6), provided therefor and having holes (7), of a machine part (5). It is characterized in that the component is designed in the form of a disk (1) which has a cutting edge (3) on its circumference, the cutting edge (3) not being formed continuously over the entire circumference but consisting of two partial cutting edges (3′, 3″) circumferentially opposite one another. In addition, the disk (1) has a central opening (2) in the form of a hexagon socket. For fitting, the disk (1) is put into the hole (7) in such a way that its two partial cutting edges (3′, 3″) point in the longitudinal direction of the groove (6), then a hexagon socket key is inserted into the opening (2) of the disk (1) and the key is turned while the disk (1) is pressed down at the same time, so that the cutting edges (3′, 3″) cut into the material of the machine part (5) and jam tight.

Abstract: A probe for measuring pressure oscillations includes an inner tube functioning as a measuring tube, an outer tube positioned so as to envelop the measuring tube, a toroidal space open to one side being defined between an outer wall of the measuring tube and an inner wall of the outer tube, a pressure transmitter, which is in connection with the interior of the measuring tube in the area of a transmitter end of the measuring tube, and a semi-infinite tube, which is connected at a first end to the transmitter end of the measuring tube, and which is connected at a second end to the toroidal space. The semi-infinite tube is constructed as a winding positioned around at least one of the measuring tube and the outer tube, thereby providing a compact and robust construction of a probe module, which is suitable especially for continuous use in the measuring of combustor pulsations in gas turbines.

Abstract: The invention pertains to a probe for measuring pressure pulsations. The probe comprises an inner tube (1) functioning as a measurement tube; an outer tube (12) arranged to envelop the measurement tube, and forming a toroidal space (14) between the inner and the outer tube; a pressure transmitter (6) which is in connection with the interior of the measurement tube on a transmitter side of said tube; a semi-infinite tube (8) with a first end in connection with the transmitter side end (3) of the measurement tube, and with a second end (11) in connection with the toroidal space. The semi-infinite tube (8) is arranged as a winding around the inner and/or outer tube, resulting in a compact and robust design of the probe, which is especially suited for a long-duration use for the measurement of combustor pulsations of gas turbines.(FIG.
