Understanding Synchro Transmitters
A synchro transmitter is an electromechanical device used primarily in control systems to transmit angular information. It plays a crucial role in various applications, particularly in remote sensing and feedback systems.
Function of Synchro Transmitters
- The primary function of a synchro transmitter is to convert the angular position of a shaft into an electrical signal.
- This electrical signal can then be used to determine the position of a corresponding device, like a control transformer.
Why Option 'C' - Error Detection?
- Error Detection Role:
- Synchro transmitters are vital in error detection within control systems.
- They provide feedback regarding the position of controlled elements, allowing for real-time adjustments.
- Comparison and Correction:
- The output signal from the synchro can be compared to a reference signal.
- Any discrepancies between these signals indicate an error in the system, signaling the need for corrective action.
Other Options Explained
- Feedback (Option A):
- While synchros do provide feedback, the term "feedback" is broader and refers to the overall control loop, not the specific function of the synchro transmitter.
- Amplification (Option B):
- Synchro transmitters do not amplify signals; they merely transmit positional information.
- Remote Sensing (Option D):
- Although synchros can be used for remote sensing, it is primarily their role in error detection that highlights their importance in control systems.
In summary, the correct answer is Option C: Error Detection, as synchro transmitters are instrumental in identifying and correcting errors in control systems through their feedback mechanism.
