Definitions

  • top 12 of the probe head 2 includes a point angle ⁇ of about 25 ° with the bottom 14 of the probe head 2.
  • the probe head 2 is symmetrical with respect to a tip plane which extends through the tip 16. Due to the circumferentially wedge-shaped probe head 2, a measurement of pressure values (total pressure values and static pressure values) of a supersonic flow is possible.
  • the circumferentially arranged pressure measuring point 4, 6 allow detection of flows of different flow direction, so that an analysis of the compressor in the boundary region of the compressor pumping is possible.
  • the main flow direction is indicated in Figure 1 by an arrow.
  • the longitudinal axis of the probe shaft 10 extends approximately at right angles to the
  • the probe shaft 10 acts approximately centrally in the region of the longitudinal axis of the probe head 2.
  • the probe shaft 10 is provided with a constriction 18 in the connection region to the probe head 2, which is formed such that the diameter of the probe shaft 10 is reduced in the region of about 8 to 10 mm in the direction of the probe head 2 frustoconical. As a result, the flow to be measured is influenced as little as possible by the probe shaft 10.
  • Probe head and probe shafts 2, 10 have pressure measuring lines 20 formed as a bore system for connecting the pressure measuring points 4, 6 with schematically indicated pressure transducers 22.
  • Each pressure measuring point 4, 6 is a Pressure measuring 20 assigned.
  • the pressure sensors 22 are arranged outside the measuring chamber, so that an extremely compact pressure measuring sensor 1 is achieved whose probe head 2 minimally influences the flow.
  • Pressure measuring probe 1 shown in Figure 1 eight total pressure measuring points 4 along the probe tip 16 of the probe head 2 are arranged offset by 45 ° to each other. The circumferentially spaced apart along the probe tip 16 arranged
  • Pressure measuring points 4 allow a 360 ° detection of total pressure values of the flow at different flow direction.
