Sep 05, 2018

A special torsion gauge plate is pasted on a special elastic shaft to form a variable bridge, which is the base torque sensor. On the shaft are fixed :(1) secondary coil of energy annular transformer, (2) primary coil of signal annular transformer, (3) printed circuit board on the shaft, including rectifier stable power supply, instrument amplifier circuit, V/F conversion circuit and signal output circuit. On the housing of the sensor are fixed :(1) the excitation circuit, (2) the primary coil of the energy ring transformer (input), (3) the signal ring transformer secondary coil (output), (4) the signal processing circuit inductor converts some form of energy into another form of energy.
