SYNCHRO EQUIPMENT

Position denoting instrumentation is used in DOE nuclear facilities to gives remote indication of equipment positions involving control rods and main valves.

DESCRIBE the synchro position indicators to involve the basic construction and theory of operation.

Position indicating instrumentation is used in nuclear facilities to give remote indication of control rod position along with respect to the fully inserted position or remote indication of the open or shut condition of important valves. This remote indication is must for the monitoring of vital components situated inside inaccessible or remote areas. A Remote position indication could be used at any DOE facility, not only nuclear facilities, whereas valve position indication is needed for safety.
