DEVICE FOR MEASURING PEAK VALUES Russian patent published in 2021 - IPC G01J1/44 

FIELD: measuring technology.

SUBSTANCE: invention relates to measuring technology and physics and can be used to isolate and control short single pulses of certain amplitudes and durations against the background of random or periodic interference of longer duration, for example, in dosimetry, vibration measurement of shock processes, flaw detection. The device for measuring peak values contains a passive sensor, the first pin of which is connected to the input of the converter amplifier, the output of which is connected via a capacitor to the first pin of the first resistor, the output of the first operational amplifier is connected to the first pin of the first diode, the second pin of which is connected via a parallel serial RC circuit and the second resistor is connected to a common bus, to which the second pin of the passive sensor, the third and fourth resistors, the second diode, the second operational amplifier and a positive or negative voltage bus, according to the invention, an additional shock excitation circuit is introduced, the first pin of which is connected to a common bus, and the second pin is connected to the inverting input of the first operational amplifier, the output of which is connected to the third pin of the shock excitation circuit, and the non-inverting input is connected to the second pin of the first resistor and the first pin of the third resistor, the second pin of which is connected either to the non-inverting input of the second operational amplifier, or to the output and inverting input of the second operational amplifier, the non-inverting input of the second operational amplifier is connected through the fourth resistor to the positive or negative voltage bus and through the second diode to the common bus.

EFFECT: claimed invention is aimed at simplifying the design, increasing noise immunity and increasing speed.
