A Method to Measure Rotary Speed and Torque Using JC Sensors
A method for rotary speed and torque measuring using JC sensors was introduced in the paper. The approximate sine signals output by JC sensors are transformed into rectangular signals by the transform circuit. The checking circuit consists of an 8031 singlechip, it determines the rotary speed by measuring the frequency of the rectangular signals, and determines torque by measuring their pulse width.
