Abstract:
A probe for measuring pressure oscillations, comprising:an inner measuring tube having a measuring point end and a transmitter end; an outer tube positioned to at least partially envelop the measuring tube, an outer wall of the measuring tube and an inner wall of the outer tube defining a toroidal space open to one side therebetween; a pressure transmitter connected with the interior of the measuring tube in the area of the transmitter end of the measuring tube; and a semi-infinite tube, a first end of the semi-infinite tube connected to the transmitter end of the measuring tube, and a second end of the semi-infinite tube connected to the toroidal space, the semi-infinite tube being constructed as a winding positioned around at least one of the measuring tube and the outer tube.
