System The XM
®
Electronic Overspeed Detection System (EODS) is a highly
reliable, redundant system that fully meets the performance, measurement, and
relay requirements of the American Petroleum Institute Standards 670 and 612
as pertaining to overspeed protection. It is intended for use on gas and steam
turbine driven machinery where protection is required to prevent potentially
catastrophic failures of the machine from overspeed events.
