-A certain model of Hall current sensor - which one to buy - [Veckway]

It is important to understand some commonly used components when considering how to use electricity correctly and safely. A certain type of Hall current sensorIt's a great example. In basic terms, a current sensor is a device that can detect the normal current passing through a wire and subsequently generate a signal proportional to the current it detects. So it tells you how much current flows through the wire. The current sensor device can detect AC current or DC current, depending on its design.Current Transformer（CT）It is used to measure currentA certain type of Hall current sensor .CTIt is around today's high current solid-state energy metersWidely recognized sensors. It can measure extremely high currents with low power consumption. It is also very useful for measuring or monitoring high current, high voltage, and high-power circuits.Used for various power systems, such as power supply, motor control, and lighting control.

Current transformer:

These sensors provide critical information for system control and safety. And generate an output signal proportional to the measured current.

A certain type of Hall current sensorcharacteristic:

Only measuringAC

Electrical isolation

No power supply

Lower cost

These sensors have been widely used in almost all industries due to their wide range of applications and the controllable and adaptable output types they provide for different applications.The current sensing voltage drop is proportional to the load current through a10RThe resistor is made up of a current transformer（CT）Step up the voltage to feed it to the bridge rectifier, generating pulsating DC power for the comparator to generate current sensing. The comparator generates zero crossing pulses from pulsed DC.

The signal generated by the current sensor is important because it tells you what is happening inside the wire. You can use this signal to do something different. You can display the signal results on the power meter or voltmeter. Alternatively, you may wish to store the signal values in a data acquisition system for analysis. Alternatively, it is common for you to use this signal to monitor and control the internal conditions of the wires. AC current sensors can be used to measure AC current amplitude, AC frequency, and AC harmonics. When used together with the voltage of the tested system, it can be determinedkWThekVAPower factorkVArWait.
