STUDY OF SYNCHRO AS AN ERROR DETECTOR MODEL IBL-AM-25

Introduction:-
The shaft angle transducer is a fundamental component in modern control technology. It is difficult to define a mechanical system. By employing direct coupling or a straightforward mechanical translation, a shaft angle can be used to monitor either type of displacement.
Encoding Methods:-

The following types of shaft angle transducers are common to the control industry.
1. Potentiometer.
2. Incremental encoder.
3. Absolute encoder.
4. Resolver.
5. Inductosyn.

Potentiometer:-
The potentiometer houses a circular ring of resistive material. A rotating contact is positioned on the resistive material according to the input shaft angle. The resistance between one end of the ring and the contact is proportional to the shaft angle. If a voltage is applied across the Potentiometer, the voltage at the contact varies according to the shaft angle. This voltage can be routed to an A/D converter to derive a digital shaft angle.

This trainer is a demonstrator. In this trainer we use a potentiometric transducer. This transducer is connected at the output of the shaft under study. The shaft is capable of rotating in the range of 0 to 3600. It is possible to set the shaft in this range. This shaft in turn rotates the transducer by the angle displayed on the shaft?s dial. The output voltage is proportional to the actual angular position. There fore it displays the rotation angle interms of angle subtended by the shaft. The output is always with reference to the 00 only. This demonstrator is housed in an elegant cabinet with necessary signal conditioner, digital display etc.
