PURPOSE:To perform highly accurate pressure measurement even under a high- temperature condition and, at the same time, to measure an unsteady pressure variation distribution. CONSTITUTION:A pressure measuring sensor which measures the pressure distribution and pressure distribution of a fluid in a flow passage R by setting a sensor cover 4 incorporating multiple pressure transducers 5 in the flow passage R and comparing the fluid pressures measured by means of the transducers 5 with each other. The transducers 5 are arranged in parallel in the radial direction of the passage R in the cover 4, directing the pressure receiving surfaces 5c at their front ends so as to directly receive the flow of the fluid. In addition, a cooling water circulating passage Q having outward and inward passages is formed in the sensor cover 4 so as to cool the front ends of the transducers 5 and their vicinities with cooling water from a cooling water supplying system.
