ABSTRACT:
A rake for measuring pressures or temperatures in a gas flow includes an elongate member which has a single recess in the front face thereof. Within the recess are located a plurality of sensors. The recess defines a single cavity around the sensors and bleed slots are provided in the side faces of the member which are in fluid communication with the cavity. The sensors are connected to a remote pressure or temperature measuring system. In operation the rake is supported in a gas flow a proportion of which passes into the cavity. The cavity decelerates the gas and removes any swirl so that the sensors take an accurate measurement of the pressure or temperature. The gas then exits the cavity through the bleed slots.
