What term is given to devices used for position-sensing in various applications?

The term "SYNCHRO" refers to a type of electromechanical device commonly used for position sensing. SYNCHRO systems are designed to measure angular position and are often employed in applications involving navigation systems, military equipment, and aircraft instrumentation. They work on the principle of electromagnetic induction, converting mechanical motion into electrical signals that can be interpreted as position information.

When a SYNCHRO device is connected to a control system, it can provide accurate feedback regarding the angle of rotation, making it invaluable for applications that require precise positioning. The technology is widely recognized and has been a standard for position sensing in various fields.

In contrast, the other options do not represent universally recognized terms for position-sensing devices. They might refer to specific systems or technologies, but they lack the established context and application that SYNCHRO provides in the realm of position sensing.
