Steam Turbine Governors

The Si-TEC Xtend ADG controllers are used for governing control of turbines requiring variable speed control.

The Si-TEC BDG (Basic Digital Governor) is a steam turbine control specially designed for mechanical drive applications (i.e. pumps, fans, shredders, mills, etc.). The BDG design is based on the very successful Si-TEC Xtend ADG steam turbine controller. The compact design, user friendly interface, onboard data logging and wide range of PIDs makes the BDG a standard choice for steam turbine control solutions.
