METSO A413144 plc control module

METSO A413144  plc control module

Turbine Generator Machine Protection

Monitoring of Turbine-Generators with

measurements of:– thrust position with eddy probes– shaft movement with eddy probes– case expansion with eddy probes or LVDT´s– differential expansion with eddy probes, single or

swap-over– shaft eccentricity with eddy probes– absolute vibration with accelerometers or velomitors

Designed according to API670 standard– Protective monitoring by the I/O cards– Cards operate even if connection into PCS is lost– Redundant power supply unit– Redundancy supported for protection only solution
