Software and Process Control

  • Process control recording and monitoring with SCADA software
  • Special programme for reports and graphic output
  • Cold silos feed flow speed is adjusted automatically according to mixture proportions and corresponding hot aggregate silo level measured via continuous level sensors (radar)
  • Required process parameters are evaluated, monitored and automatic controls are carried out accordingly.  Heat monitoring thermocouples and infrared heat sensors, material level radars, capacitive sensors, motorized level sensors and level switches, air-pressure and vacuum monitoring sensors and moisture sensors are used to control production processes.
  • E-MAK’s automation remote control system supports asphalt plants assembled throughout the world
