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

Component for holding down measuring leads

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.
