FIELD: measuring technology.
SUBSTANCE: invention relates to the field of measuring technology and can be used to measure the angle of position and linear movements of moving elements of aircraft, transport objects and ships. The device contains two identical channels connected in parallel, the main and backup, in which stabilized voltages are generated to supply the potentiometric sensor and a signal is measured proportional to the angular position and linear movement of the controlled object. The main and backup channels are identical in structure and contain a reference voltage source, to the output of which the input of the ideal diode controller chip and the source of the field-effect transistor are connected. The outputs of the main and backup channels are connected to one of the extreme terminals of the potentiometric sensor. The gates of the field-effect transistors are connected to the output of the controller chip of the ideal diode, which forms the gate control voltage. The middle output of the potentiometric sensor is connected to the inputs of the ADC built into the microcontrollers of the corresponding channels: main and backup.
EFFECT: increase in the reliability of the formation of stabilized voltages for powering a potentiometric sensor and an increase in the reliability of measurement results.
