High precision - Hall current sensor with clamp - Supplier [Weikewei]

There are two commonly used methods for current sensing: low-voltage side sensing and high-voltage side sensing. Low voltage side induction willHall current sensor with clampConnect 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帶夾鉗霍爾電流傳感器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. 霍爾效應(yīng)傳感器用于鉗形儀表以及許多工業(yè)和汽車電流傳感應(yīng)用中。許多類型的線性霍爾效應(yīng)傳感器可以感應(yīng)從幾毫安到幾千安培的電流。因此，智能電網(wǎng)監(jiān)控應(yīng)用還采用了不同類型的霍爾效應(yīng)傳感器來監(jiān)控導(dǎo)體電流。
