This report describes and characterizes the mounting, operation, and behaviour of the wall shear stress sensor 55R45 applied to the flow in a turbulent boundary layer at moderate Reynolds numbers. Additionally, the results obtained will be compared with canonical trends and other kind of measurements of the mean shear stress to assess the accuracy of the measurements.
