DEVICE FOR MEASUREMENT OF ROTARY TRANSFORMER STATIC ERROR Russian patent published in 2009 - IPC G01R35/02 H03M1/10 

FIELD: physics.

SUBSTANCE: invention relates to the area of measurements, it can be used at metrologic analysis of syncro resolvers. Suggested device contains angle-setting block (1), rotary transformer (2), analog-to-digital converter (ADC) (3), digital data display (4) computing device (5), monitor (6), digital-to-analog converter (DAC) (7), alternating current source (8), switch (9). Rotary transformer (2) is fixed at angle-setting block (1); signal winding of transformer are connected to the first input of switch (9), its output is connected to input of ADC (3); ADC output is connected to digital data display (4). Output of DAC (7) is connected to the second input of switch (9); reference voltage input of DAC is connected to AC source (8); digital input of DAC (7) is connected to interface of computing device (5), which video output is connected to monitor (6).

EFFECT: functionality enhancement by means of introduction of error monitoring in suggested device.
