A housing (6, fig 1) for a wind sensor (2, fig 1) with a sensing element (4, fig 1) and processing element (8, fig 1) mounted in the housing to measure the speed of the passing fluid air flow, and the housing comprises at least one surface 40, 42 having shaped surface elements 38 in the form of protrusions and/or indentations on the surface for inducing turbulence in the fluid air flowing across the surface. The housing having a body, with a first housing portion 12 and a second housing portion 14, with a cylindrical cross-section, comprising of a first reflector and a second reflector coaxially mounted by spacers 20 with the first reflector, to define a resonant cavity 24 between the first and second reflector. The turbulence caused by the shaped surface elements results in the speed measured by the wind sensor being less affected by uncontrolled transitions between laminar and turbulent airflow, enabling more accurate measurement and calibration of the wind sensor. |
