Abstract :
This paper emphasises the means and technology that measures transmission shalt torque on the vehicle. It is based on the characteristic that magneto-sensitive elements can exactly measure micro displacement. It utilizes a single-chip computer and I/O circuit to measure relative torsion angle of shaft in the demarcated length. It can precisely measure transmission shaft torque
