Weikewei, an agent for special aerospace Hall current sensors

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 for aerospace applicationsConnect 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 seriesHall current sensor for aerospace applicationsComposed 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. 羅氏線圈有著廣泛的應用。例如，測量大功率模塊中的電流，特別是跨MOSFET或大功率晶體管或跨IGBT的電流。羅氏線圈提供靈活的測量選擇。由于Rogowski線圈對暫態(tài)或高頻正弦波的響應非常快，因此它是測量電力線高頻電流暫態(tài)的一個很好的選擇。在配電或智能電網中，羅氏線圈為電流測量提供了極好的靈活性。
