SURFACE SENSOR Russian patent published in 2022 - IPC G01L19/00 H01H35/14 

FIELD: instrumentation.

SUBSTANCE: invention relates to the field of instrumentation, in particular to sensors used in automatic systems for underwater inhabited and uninhabited objects. The ascent sensor contains a housing and a channel for receiving hydrostatic pressure, in the housing with the formation of an internal volume there is a housing in which the membranes are coaxially fixed. One membrane - the main one - is combined with another - an additional membrane with a similar main profile, installed in the main one and hermetically connected to it along the outer contour, while the additional membrane, having a hole in the center, is hermetically fixed on the body, in which a hole is made coaxial with the membranes with an installed a pusher with an insulated end facing the membranes and a thread on the other end with a screwed threaded sleeve with the possibility of locking on the rod after adjusting the ascent sensor and fixed on a flat movable elastic contact mounted on the insulator, located on the body, and the pusher interacts with an isolated end face with the inner center of the main membrane with the possibility of tracking its movement, the sensor is also equipped with a fixed contact in the form of a threaded rod and with a contact pad located in the insulator hole perpendicular to the membrane axis, and a channel for receiving an external hydrostatic pressure is made in the housing.

EFFECT: simplifying the design and improving manufacturability, increasing resistance to overload pressure and reliability.
