Overspeed protection is a key requirement in the power generation industry where failure of the turbine or pump speed governing system can lead to rotor damage with expensive consequences. Independent speed monitoring and protection is therefore an essential requirement to minimise these risks as far as practicable. Condition monitoring specialists SENSONICS have provided high integrity overspeed protection systems for over 20 years with proven field reliability. The design of the system and functions offered have been developed and enhanced in conjunction with our customers in both the conventional and nuclear power industry, resulting in a highly reliable hardware configuration with online test facilities.
