In wind tunnels and elsewhere whenever localized pressures, pressure fluctuations, pressure patterns, etc., are being monitored by pressure sensing transducers in which diaphrams are being used as the initial sensing elements, protectors are provided upstream to direct unwanted particles moving in the fluid streams to impact absorbing structures before reaching the diaphrams Such protectors in their assemblies are arranged in reference to the diaphragms so the directional changes of the fluid streams will not interfere with the accuracy of the observed and/or recorded pressures.
