Potentiometric Error Detector | Position Error Measurement Trainer for Control Systems

Description

The Potentiometric Error Detector Trainer is a precision educational apparatus designed to demonstrate the principle of error detection in control systems using a potentiometer. This trainer helps students understand how positional difference between a reference input and an output shaft generates an error signal, which is fundamental in servo mechanisms and closed-loop control systems.
Ideal for control system laboratories, electronics labs, engineering colleges, universities, polytechnic institutes, and technical training centers.
