Potentiometric Error Detector

Get Price Quote

We offer Potentiometric Error Detector useful for control labs. All feedback control systems operate from the error signal which is generated by a comparison of the reference and the output. Error detectors perform the crucial task of comparing the reference and output signals. The present set-up is designed to study the important characteristics of a 2-potentiometer angular position error detector. These include (i) linearity, (ii) sensitivity and (iii) maximum angle of rotation. Good quality wire wound servo potentiometers with full 360 degree rotation have been used for this purpose. Accurately marked dials with least count of 1degree are fixed on the shafts for position indication. The error voltage is read on a built-in 3.5 digit DVM. An I.C. regulated internal reference voltage is available for d.c. studies. When used with an a.c. reference, the unit also demonstrates the phase reversal of the error signal which is important in applications involving a 2-phase servomotor as actuator. Highlights >>High quality servo potentiometers >>360 degree Mechanical, 355 degree Electrical span >>DC and AC operation >>3.5 Digital Panel Meter for all measurements Experiments >>Linearity study of the error detector >>Determination of error detector gain >>Use of a.c. supply for the error detector-introduction to the phase reversal of error signal Features and Specifications >>High quality servo-potentiometers of 360 degree shaft rotation >>Requires an external CRO for a.c. studies >>Built-in signal and power sources >>3.5 digit DVM for measurements The experiment is complete in all respect, except a CRO.

The present set-up is designed to study the important characteristics of a 2-potentiometer angular position error detector. These include (i) linearity, (ii) sensitivity and (iii) maximum angle of rotation. Good quality wire wound servo potentiometers with full 360° rotation have been used for this purpose. Accurately marked dials with least count of 1° are fixed on the shafts for position indication. The error voltage is read on a built-in 3½ digit DVM. An I.C. regulated internal reference voltage is available for d.c. studies. When used with an a.c. reference, the unit also demonstrates the phase reversal of the error signal which is important in applications involving a 2-phase servomotor as actuator.
