CAPACITIVE PRESSURE TRANSDUCER AND PROCESS OF ITS ASSEMBLY Russian patent published in 1998 - IPC

Abstract RU 2116636 C1

FIELD: instrumentation engineering. SUBSTANCE: invention makes it possible to measure force and pressure of various objects of any configuration and may be used in automated test and control systems. Membrane and base of transmitter are manufactured from thin foiled dielectric film. Transmitter has compensation sensitive element with compensation cover and measurement sensitive element with cover. Dielectric film to protect membrane from mechanical damage is cemented to upper surface of membrane. Sensitive element of transmitter is protected from external electromagnetic noises by two screens. Individual elements of transmitter are interjoined by cement on epoxy-rubber base. Assembled package is held under pressure of 30.0-35-0 kg/sq.cm at temperature 160-170 C in the course of 50-60 min. EFFECT: expanded application field of pressure transducer. 2 cl, 1 dwg
