current sensor It is an electrical deviceDual Hall Effect SensorUsed to measure the current along a specific wire. It achieves this by measuring the voltage drop across the resistance on the current path. This allows the current sensor to generate an estimate of the current level flowing through the circuit.Current sensingThe output of the device can be a voltage reading or a continuous current, which is roughly proportional to the level of current moving along the test path.

In frequent electronic systems, inducing variable current is a major requirement, and the strategy for doing so is as a classification of the application itself. A dual Hall effect sensor is a unit that can determine a physical phenomenon and calculate the latter, in other words, it provides a measurable demonstration of miracles within a specific scale or range. A current sensor is a device that can identify whether the current in a wire or system is high or low, and generate an indicator related to it. Then it can be used to represent the current measured in the ammeter, archived in the data acquisition system for further classification, or used for control purposes.current sensor yesInterference, as it is a combination of sensors, may affect system performance.

There are various current sensors to monitor AC or DC current, which are required for measurement in many applications in industrial, automotive, or household fields.A current sensor is a device that detects and converts current to obtain an output voltage, which is proportional to the current in the design path. When current passes through a circuit, the voltage will decrease along the path through which the current flows. In addition, a magnetic field is generated near the current carrying conductor. These phenomena are used in the design technology of current sensors. 这种电流传感技术的另一种方法是使用PCB迹线作为并联电阻器.由于PCB的铜线提供非常小的电阻,因此可以使用铜线来测量电流。然而,在这种替代方法中,要获得准确的结果,几个依赖项也是一个巨大的问题。

In order to reduce power loss, the value must be taken low: the current sensed value usually depends on the threshold voltage of the circuitDual Hall Effect SensorThe operation is entirely based on the sensed current information.In order to improve accuracy, we must consider the low-temperature coefficient:In terms of accuracy, temperature is the main coefficient of resistance. A resistor with a temperature coefficient resistance close to zero should be used throughout the entire operation process. The power derating curve provides the allowable power at different temperatures. But the peak power capacity is a function of energy, so the energy rating curve should be consideredIntroducing additional resistors in the tested circuit path may increase the source output resistance and produce adverse load effects. Due to the direction of power dissipation, power loss occurs. Therefore,Current sensing resistorRarely used outside of low and medium current sensing applications.
