METHOD TO PRODUCE HEAT-LOSS ANEMOMETER (VERSIONS) Russian patent published in 2015 - IPC G01P5/12 G01M9/06 

FIELD: measurement equipment.

SUBSTANCE: invention relates to measurement equipment and may be used in aerodynamical experiments, in power engineering of turbine machines when researching gas flow structure in fluid. Sensor design is developed on the basis of polyimide film. On this film they generate sensor design of moderate temperatures up to 300°C on the surface of items by the method of cathode sputtering of metals in vacuum. The cathode method of sputtering makes it possible to spray an insulating film from aluminium oxide and a protective film for protection of items (model) from oxidation. The sensitive element is manufactured, for instance, from nickel, collecting outputs are formed from gold or other materials. Elements of sensors are formed, using two masks or by means of electrical engraving. Prior to metallisation the surface of the polyimide film is activated by the method of glow discharge. Optimal methods of metallisation in vacuum plants are chosen.

EFFECT: invention provides for expansion of application field, increased accuracy and reliability of measurement during research of gas and fluid flow.
