There are two commonly used methods for current sensing: low-voltage side sensing and high-voltage side sensing. Low voltage side induction willOpen-loop 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 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开环式霍尔电流传感器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. 钳位式交流电流传感器就是为了限度地利用这些特性而研制的。随着工业4.0能源管理系统市场的扩大，韦克威已开发出一系列兼容30A至600A的交流电流传感器，以满足对大电流支持的需求。这些产品是一触式夹具，这意味着它们很容易连接到现有的电力设备。
