A method of on-line measurement of constant torque variable rotation rate based on PLC

ZHANG Jie;MA Fengming;ZHANG Yining;School of Physical Science and Technology,Anshan Normal University;  
A method of measuring wide-range rotation rate is introduced in this paper. In this method S7-200 PLC is used as the core and incremental photoelectric encoder as the detection component.By frequency method of varying gate time,the on-line measurement could not only be wide-ranging,but also with high-resolution.
