DEVICE FOR MEASURING VOLTAGE SIGNALS AND TRANSMITTING MEASURED VALUES OVER TWO-WIRE COMMUNICATION LINE Russian patent published in 2023 - IPC G01R19/255 G01K7/21 G08C19/02 

FIELD: measurement; transmission of signals.

SUBSTANCE: devices for measuring the voltage of signals and transmitting them over a two-wire communication line. The device contains a counter-divider by two, a time interval former, three analog switches, an RS trigger, an integrator, a null organ, a current pulse shaper with the ability to increase the current consumption of the device and transmit signals in the form of time intervals carrying information on two measured parameters, the outputs of the current pulse shaper are connected in parallel to the power and data lines, the input connected to the control input of the third analog switch is connected to the output of the RS trigger, the first input of which is connected to the output of the second analog switch, the first input of which is connected to the first output of the time interval shaper, and the second input is connected to the second output of the time interval generator.

EFFECT: creation of a device for measuring signal voltage and transmitting measured values over a two-wire communication line, ensuring its use in measuring transducers with two measured parameters, as well as in hazardous areas as a two-wire transmitter.
