Some Common Current Sensors

In electrical engineering, current sensor is any one of various techniques utilized in order to measure current. The measurement of current varies from microamps to millions of amps. It is the ability to determine the amount of current passing through an electric circuit. The amount of current passing through a circuit is called primary current or alternating current and the measurement of alternating current is called secondary current, or alternating current.

There are different types of DC Ammeter Shunt and all have their own advantages and disadvantages. The most common current sensors are resistive, electromagnetic and opto-electronic. Resistive current sensor can be described as a device that measures current using resistance. Electrical measurements are made by measuring the voltage across a junction. This is done by connecting two or more conductors that form a conductive link.

In a resistive current sensor, the signal output is proportional to the value of its resistance. Because of the low output resistance, this device is ideal for making measurements of small electric currents. If the output voltage is high then the process of conversion to proportional output current will not occur.

A Faraday cage is a type of DC Ammeter Shunt electric circuit that has no gap between the metal layers of the circuit. This makes the circuit resistant to electromagnetic interference. The term Faraday cage generally refers to any device that has a layer of metal having a low permeability in the Faraday field. One of the most common materials used in building Faraday cages is tantalum. However, another material commonly used is copper which has a similar property.

Another type of current sensor is the shunt resistor. The shunt resistor is also a magnetic component that is sensitive to changes in magnetic field. When a current passes through the shunt resistor, it alters the magnetic field inside the circuit. Thus, the current will become proportional to the change in magnetic field. The shunt resistor normally comes in two types, the first having two poles and the second having three poles.

These are some of the most commonly found current sensors. For more information on how they work, you may consult the manuals or websites of the manufacturers. If you need any help in understanding the concepts behind the various types of current sensors, you may ask for help from the sales representatives. By consulting these resources, you will be able to understand the concept of the different kinds of current sensors and how each of them work. Learn more about electronics at
