DIGITAL GRAVIMETER Russian patent published in 1997 - IPC

FIELD: radio engineering. SUBSTANCE: device has vacuum protected drift chamber which contains electron source, modulating electrode and anode which are located in series along sensitivity axis. In addition device has controlled generator of modulating pulses, pulse counter and digital computer, which transmission acknowledgment line is connected to common point of control input of generator of modulating pulses, rest input R of pulse counter, which counting input C is connected to modulating electrode and output of controlled generator of modulating pulses. Counting permission input CE is connected to anode. Output of pulse counter is connected to data line of digital computer which output generates digital value of gravitation. EFFECT: increased speed, decreased size, increased precision. 2 dwg
