PROCESS OF MANUFACTURE OF MATRIX PRESSURE TRANSDUCERS Russian patent published in 1997 - IPC

Abstract RU 2075735 C1

FIELD: measurement technology, pressure measurement during aerodynamic and full-scale tests of aviation equipment. SUBSTANCE: matrix pressure transducer is formed right on surface of model of complex configuration with high curvature. Polyamide varnish layers are applied in sequence, each layer is thermally treated. Produced polyimide films are metallized by continuous layer, plates with leads and screen are engraved on metallization layer. Transducer is formed on surface of model in three layers of polyimide film thickness 50.0-60.0 μm. Decrease of edge effects in achieved by selection of gas between screen and plates. EFFECT: enhanced reliability, quality and decreased cost of transducer. 2 cl, 1 dwg
