Torque Output Characteristics
Torque and output voltage have a strict positive linear relationship. The measurement range of 0~80N·m maps directly to an output voltage of 0.74~3.3V. The greater the pedaling torque, the higher the output voltage, enabling the controller to accurately calculate pedaling force.
Speed Pulse Output Characteristics
The sensor outputs a fixed pulse count per rotation (32 or 36 pulses) with a highly stable 40%~60% duty cycle across a full 0~360° crank rotation. The controller calculates cadence and riding speed based on this pulse frequency.
