There are two commonly used methods for current sensing: low-voltage side sensing and high-voltage side sensing. Low voltage side induction willHall DC low 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 usually requires a more expensive sensor-As a higher level of accuracy is necessary-But it will not damage the grounding current like current sensing through the low side connection.

Our company produces various series霍尔直流小电流传感器Composed 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) through solid-state or split type current sensing loopsone hundred and fiftyAmpere).

The model has a fixed or adjustable current sensing trigger point or voltage output. Externally visibleLEDIndicate the status of the relay coil and current sensor trigger. Provided on certain models (closed)-open-The automatic override switch 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.58彩票 电流互感器或电流互感器是通过二次电压来检测电流，二次电压与二次线圈中的电流成比例。它是一种工业变压器，它将电压或电流的大值在次级线圈中转换成小得多的值。测量通过次级输出进行。
