ECE Seminar Topic on Universal Sensor Current with Full Report

Introduction to Seminar Topic on Universal Sensor Current:

When we talk about measuring electric current it is not the easy task. We require sensors for that so that we can feed the data into the computer to convert the current. In earlier times we find the current by finding the voltage drop across the resistor. For that we need to keep the resistor very small so the energy loss is small. Few places we also transformers but it don’t allow DC signals.

Hall sensors: these sensors are used for measuring the magnetic field around the conductor. They are also capable of sensing DC signals. They provide galvanic isolation to the conductor. There are two types of hall sensors are available. In Open loop output amplifies voltage is directly used. They are cheap sensors and they are very sensitive while closed loop sensors are precious. They first amplify the signal then the signal goes to magnetic core.

Magneto field sensors:they are sensors based on the magnetic and resistive effect. They are very thin in size and easily fabricated with vary length and size. They are best performance sensors. They are very well designed for measuring the electric current and they do have the impact of external field applied. They can measure both AC and DC signals.

AMR effect: when these materials are exposed to the magnetic field then the magnetization of the material results. This effect is mostly observed in ferromagnetic alloys.

Current sensors for future vehicles: it will help in increasing the efficiency of vehicles by improving the engines starting speed and power consumption will increased by the generator and power requirement by the engine is same as required. We can start and off the engine whenever we require which in turn will reduce the fuel consumption.
