Item Name:
SYNCHRO , TRANSMITTER
Definition:
A SYNCHRO CONSISTING OF A STATOR AND ROTOR INDUCTIVELY COUPLED. THE ELECTRICAL OUTPUT OF THE STATOR INTO A RECEIVER SYNCHRO, A CONTROL TRANSFORMER OR DIFFERENTIAL SYNCHRO IS DEPENDENT UPON THE POSITION OF ITS ROTOR. DOES NOT INCLUDE VARIABLE RESISTORS, GONIOMETERS, VARIABLE TRANSFORMERS, OR ITEMS WITH DIALS.
