thumb speed turbine control

  • Precise speed governing typically within 0.1 % of operating speed at steady state
  • Dual MPU (or prox.) speed sensors for redundancy
  • Auto run up and warm through
  • Interpolating multiple speed PIDs
  • Process control
  • Variable speed governing control referenced from internal or external set points
  • Constant speed governing control referenced from internal set points
  • Controlled test of overspeed protection
  • Extensive alarm functions
  • On-board diagnostic
  • Dedicated communications port for customer PLC/DCS interface
  • Compatible with all Si-TEC support PC software
