CONTACTLESS PRECISION DYNAMIC TORQUE SENSOR Russian patent published in 2024 - IPC G01L3/10 

FIELD: measuring.

SUBSTANCE: invention relates to instrument-making equipment, namely to design of torque meters used to measure torque on a shaft. In a device comprising a rotor with placed on it a strain gauge bridge, a transformer with a fixed winding and a winding made with possibility of rotation, a rectifier with an integrated voltage stabilizer, torque measurement module, the transformer is made as a rotor, is covered with a protective screen and consists of two cup-type magnetic conductors installed inside, annular stator and rotor windings. At that, annular stator winding is connected to high frequency generator, and the annular rotor winding is connected to a rectifier with an integrated voltage stabilizer, which is connected to a torque signal digital processing and transmission module with a strain-gauge bridge, which are mounted on a deformable spring. Torque measurement module comprises torque signal digital reception module mounted on end shield.

EFFECT: improved noise immunity and stability of measurement of torque value.
