FIELD: measuring technology. SUBSTANCE: device is intended for determination of angular position of shaft or other member of actuating mechanism. Device has an angle-data transmitter with three phase outputs, for example, selsyn connected to inputs of synchronous demodulator. Three multipliers provide for multiplication of signals at synchronous demodulator output with output signals of three phase inverters. Sum of products obtained at adder output is integrated by integrator and displayed on indicator. Zero-setting unit of device is connected to feedback circuit placed between integrator output and inputs of phase inverters. EFFECT: higher accuracy. 1 dwg
