PRESSURE SENSOR WITH NORMALISED OR DIGITAL OUTPUT Russian patent published in 2015 - IPC G01L9/04 

FIELD: electricity.

SUBSTANCE: pressure sensor with normalised or digital output comprises a body with a pressure cell installed in it having IC chip of pressure transducer (PT) and contact pads, IC chip of PT signal converter, protective cover for the pressure cell and IC, output contacts, electric connectors for the pressure transducer, IC and output contacts and a channel in the body intended to supply pressure to the medium. The pressure cell is completed with contact pads, and this type of PT design simplifies and allows automation of the connection process of PT, IC and output contacts with electric conductors. The cover is made of silica and in-built as per IC manufacturing technology, i.e. it is placed inside the body cavity at IC chip and its connection with IC chip is also made of low-temperature glass soldering thus allowing, as known, reduction of thermal stress at IC chip during operation.

EFFECT: placement of IC chip at in-built protective cover of IC chip and their connection with sealing glue improves operating conditions and simplifies assembly technology.
