AUTONOMOUS DEVICE FOR MEASURING THE CHARACTERISTICS OF A FLUID CIRCULATING IN A DUCT AND CONTROL SYSTEM FOR VENTILATION, AIR CONDITIONING AND / OR HEATING USING SUCH A DEVICE

摘要

The invention relates to a self-contained device (10) for measuring at least one characteristic of a fluid flowing in a conduit in a direction of flow. The device comprises a rotor (11) comprising a turbine (11a) formed by a hub (11b) and a plurality of blades (11c) fixed to the hub (11b), the turbine (11a) being capable of being driven in rotation by the fluid, the rotor being assembled with a stator (12) to form a generator which transforms the kinetic energy of the fluid into electrical charges. The device comprises a bypass passage bypassing the blades (11c) of the turbine (11a) and forming a passage for circulation of the fluid which does not promote the setting in rotation of the rotor (11).
