MEASURING DEVICE USING CANTILEVER BASED ON FIBERS, BUILT INTO CARTRIDGE Russian patent published in 2019 - IPC G01N11/16 

FIELD: measurement.

SUBSTANCE: present invention relates to a measuring device for measuring physical properties of a fluid medium using cantilevers based on fibers embedded in a cartridge. Fluid measuring device comprises a light source, a photodetector, an electromagnet for forming a time-varying magnetic field, a processing unit for processing the output signal of the photodetector and creating a measurement signal in accordance with the physical property of the fluid, and a cartridge which is detachably connected to the measuring device. Cartridge comprises at least one fluid channel, at least one optical channel, at least one chamber located at intersection of fluid channel and optical channel, at least one optical waveguide located in optical channel, wherein the optical waveguide is at least partially contained in the corresponding chamber, wherein the optical waveguide has a movable section, and vibrations of the movable section can oscillate from the outside.

EFFECT: technical result is creation of measuring device for measurement of physical properties of fluid medium using cantilevers based on fibers, which does not require active adjustment.
