FACILITY MEASURING TOQUE Russian patent published in 2003 - IPC

FIELD: measurement technology, measurement of parameters of rotating shafts, such as stress, deformation, torque and shaft horsepower. SUBSTANCE: facility incorporates resistance strain gauge, resistor and power supply source connected in series. Resistance strain gauge is properly anchored on rotor and is connected to elements of circuit arranged on stator through current pickup contacts. Facility also includes three voltage followers based on operational amplifiers, voltage inverter, three-input voltage adder and divider. EFFECT: enhanced functional reliability and accuracy of facility measuring torque, widened operational potential. 1 dwg
