VACUUM SENSOR Russian patent published in 2011 - IPC G01M3/00 G01L21/34 

FIELD: physics.

SUBSTANCE: vacuum sensor has a housing, a coaxial cylindrical anode, disc-shaped cathodes connected by a centre rod, and magnetic system composed of two disc-shaped permanent magnets which, together with the coaxial cylindrical anode and the disc-shaped cathodes, are placed in the sensor housing with holes. The coaxial cylindrical anode also has holes. The holes in the housing of the sensor lie above holes in the housing of the coaxial cylindrical anode. Inside the coaxial cylindrical anode on the disc-shaped cathodes, there are disc-shaped permanent magnets and each pair of disc-shaped cathodes and disc-shaped magnets is to each other and mounted inside the cylindrical anode by dielectric holders.

EFFECT: reduced weight and size.
