SENSOR SYSTEM Russian patent published in 2018 - IPC G01D11/24 

FIELD: metrology.

SUBSTANCE: invention relates to metrology, in particular to sensors for measuring flow, pressure, temperature. Sensor system contains a sensor, a housing that consists of two polymer molded parts and protects the electronic components located on the board. Inside the housing there is an absorption element which is made in the form of a polymer molded part under pressure and serves to absorb a liquid that could enter the housing due to diffusion. In this case, the absorption element is provided with spacers that hold it at a certain distance from the body. Both body parts are sealed against each other by means of a circular annular element. Absorption element is made together with the hull part by the multicomponent injection molding method. Electrical wire is passed through the lid with sealing, and an annular seal is located between the housing and the wire. Wire is covered with an electrically insulating shrink tube and filled with a polymer material. Absorption element has a springy tongue which is adapted to engage with a recess or protrusion on the printed circuit board.

EFFECT: technical result is an increase in the protection efficiency of the sensor electronics against moisture.
