Application of EDA9033 in On-line Monitoring System of Ventilator Performance

This paper presented the characteristic of data collecting module of EDA9033 for measuring the three-phase electrical parameters of motor. The application of the module in the on-line monitoring system of main mine ventilator performance based on 80C552 SCM and long-distance communication system was introduced. It improved the monitoring accuracy and reliability for three-phase electrical parameters and integration of the system by using this module.
