The invention relates to the technical field of testing, in particular to a rotating blade pressure field measuring device which comprises a rotating shaft, one end of the rotating shaft is sleeved with a rotating part, the rotating part comprises a plurality of rotating blades, and the rotating blades are evenly distributed on the surface of the rotating part; the plurality of pressure sensors are adhered to one side of the rotating blade; and the signal conditioning acquisition system comprises a first signal conditioning module, a conductive slip ring and a second signal conditioning module which are respectively used for realizing primary conditioning amplification, dynamic and static transmission and secondary conditioning amplification of signals. By means of the advantages of a flexible sensor or a thin film sensor, the blade is integrally wrapped from the front edge to the tail edge under the condition that the blade structure is not damaged, the influence on a flow field is minimized, meanwhile, the
