Electronic measuring system with pulsed transducer

摘要

The electronic measuring system includes a novel power supply which may receive power from a D.C. or A.C. source but which is particularly adapted to convert D.C. battery power to higher voltage pulses to drive a transducer. During intervals between transducer power pulses, an automatic drift compensation system stores an indication of system drift for use during a subsequent power pulse period. The system includes stability sensing means which render the system inoperative for measurement purposes when the signal from the measuring transducer is unstable. To compensate for a loss of time, the system automatically operates for a short period at a rapid rate subsequent to a period of input signal unstability.
