ACCELERATION METER Russian patent published in 1995 - IPC

FIELD: instruments. SUBSTANCE: device has housing where sensitive element is attached to. Both sides of sensitive element have resistive heaters and main and additional transducers of surface acoustic waves are made on sensitive element. Side of housing that is opposite to main transducer has metal coated pieces. generators are made on basis of transducers. signals from transducers-generators are received at subtraction units and adder. From subtraction units signal is transmitted to subtraction unit and frequency meter. signal from adder and clock generator is processed by subtraction unit which output is connected to resistive heaters through power amplifier. EFFECT: increased functional capabilities. 5 dwg
