DC Current Sensor

A DC current sensor output voltage varies as a response to a magnetic field that the sensor comes into contact with making use of their Hall effect (discovered by Edwin Hall in 1879) principle. DC Current Sensors are used for proximity switching, positioning, current sensing application and speed detection. When a different voltage is produced through any type of electrical conductor the effect is the ‘Hall Voltage’. As well as having perpendicular magnetic field in relation to the current, the voltage is transverse to the electric current itself.

DC current sensors are often use together with circuitry that makes it possible for the machine to digitally act on or off. As such, it is often referred to as a switch. We see this in many industrial applications and consumer equipment. Due to the DC current sensor reliability and accuracy they are becoming common place. One can use a DC current sensor to measure how fast a shaft or wheel is moving. This can be in an anti-lock breaking system, a tachometer or an internal combustion engine. A DC current sensor can also be used to detect where the permanent magnet is in electric motors. The DC sensor’s voltage will peak twice in each single revolution if the magnets are spaced equally and we usually see this to make sure disk drives have the right speed.

A DC current sensor uses the ratio of the electric field that’s induced to the current density’s product and the applied magnetic field. This is called Hall coefficient. What is applicable to this is the characteristics of the material that is used in the creation of the conductor. This means however that the value in the DC current sensor varies depending on the number, the type and other properties of what is carrying the charge that makes up the current. The distance can be determined from the Hall plate if there is a known magnetic field in the DC sensor. It is possible to deduce what the relative position of the magnet is by using a number of DC current sensors together.
