Abstract

The invention discloses a ceramic sensitive core based on high temperature co-sintering and a preparation method thereof, and belongs to the technical field of high temperature sensors. The ceramic sensitive core and the preparation method solve the problems that an existing varnished wire preparation technology for a sensor core cannot meet the requirement of an ultra-temperature measurement environment, and the precision of a sensor prepared by adopting the existing preparation technology is low. According to the ultra-temperature displacement sensor, namely the ceramic sensitive core basedon high temperature co-sintered ceramic, N layers of functional layer substrates are subjected to high temperature co-sintering, the ceramic sensitive core is formed, and N is a positive integer greater than or equal to 2; the functional layer substrates comprise ceramic substrates, spiral coils, filling ceramic and signal leading-out holes; the ceramic substrates are rounded, the spiral coils ina spiral shape are printed on the ceramic substrates, and the filling ceramic is overprinted on blanks of the ceramic substrates; the rotation directions of the spiral coils on the adjacent functionallayer substrates are different. The ceramic sensitive core based on high temperature co-sintering and the preparation method thereof are applied to preparation of the high temperature sensors.
