FIELD: data processing.
SUBSTANCE: invention relates to means for transmitting data through an air gap using inductively coupled circuits excited by an acute-angled impulse, with telemetry measurements from the working members of rotating assemblies and mechanisms. In the method, as the excitation signal of the inductively coupled circuits, an acute-angle pulse is used, generated by a subtracting counter and a digital-to-analog converter. Device contains the device pulse generator on the rotating part, AND element, clock generator, subtracting counter, digital-to-analog converter, driver of the impulse excitation signal, primary circuit of the inductively coupled circuits, and their secondary circuit on the fixed part. Single data code sending transforms all counter bits to a single state and starts a linear reduction of the counter code to zero. Digital-to-analog converter connected to the counter generates an acute-angle pulse that drives the primary circuit through the driver.
EFFECT: technical result is to increase the noise immunity of the transmitted data.
