LINEAR ACCELEROMETER Russian patent published in 2014 - IPC G01P15/11 

FIELD: measurement equipment.

SUBSTANCE: into a linear accelerometer, comprising inertial mass on elastic suspensions, a position sensor comprising a pair of emitters and a pair of photodetectors, a base, a cover, a comparator, a key, a DC source and current-conducting paths, differing by the fact that the device additionally comprises pole tips placed on the base and the cover, being magnetic conductors, onto end surfaces of which an insulator is applied, onto which current-conducting paths are applied, the starts and ends of which are connected to each other, besides, the starts are connected to the first output of the key, and the ends - to its second output, a DC source is connected to the input of the key, and emitters are connected to the third and fourth inputs of the key, and optical axes of emitters match with optical axes of photodetectors, outputs of which are connected to the first and second input of the comparator, and stretch via optical slots of the inertial mass made in the form of a rectangular plate placed in the gap between the cover and the base with the possibility of linear displacement, current-conducting paths are sprayed on the cover and base, as a result of which it becomes possible to supply higher current into the system, which in its turn results into higher sensitivity of the linear accelerometer.

EFFECT: higher sensitivity of a device.
