There are two commonly used methods for current sensing: low-voltage side sensing and high-voltage side sensing. Low voltage side induction willBipolar Hall current sensorConnect between the original load and the ground connection. This type of sensing provides an inexpensive method for measuring current, but has a drawback of adding additional resistance to the grounding path of the circuit. On the other hand, the high-voltage side induction connects the sensor between the power supply and the load. It typically requires a more expensive sensor - as a higher level of accuracy is necessary - but does not compromise ground current like current sensing through a low side connection.

Our company produces various seriesBipolar Hall current sensorComposed of a current switch and a current sensor. These sensors come with optional embedded relays that can be used to activate external contactors. They can induce external currents (up to 150 amperes) through solid-state or split type current sensing loops.

The model has a fixed or adjustable current sensing trigger point or voltage output. The externally visible LED indicates the status of the relay coil and current sensor trigger. The (close open automatic) override switch provided on certain models is a true override switch located on the load side of the relay.

In electronic or electrical engineering, current is a crucial factor. In electronics, the bandwidth of current varies from a few milliamps to several hundred amperes. In the electrical field, this range can be wider, typically reaching several thousand amperes, especially in the power grid. There are various methods for sensing and measuring the internal current of circuits or conductors. In this article, we will discuss the advantages and disadvantages of using various current sensing technologies to measure currentPoints and applications. The working principle of Hall effect sensors is similar to that of flux gate sensors, but there is a difference between the two. The difference lies in the core materials. The flux gate sensor uses a saturated inductor, while the Hall effect sensor uses a hollow core.
