Weikewei, a manufacturer of closed-loop Hall current sensors

OneClosed loop Hall current sensorNo matter what type it is, it willPerceive what is happening and tell you what is happening. Then this information can be used for many final results. This may be because you only want to monitor what is happening - which is important because if you don't know what is happening, you won't be able to react when needed. Sensors are monitoring you so that you can ensure that the device is functioning properly, or you can check if any non compliant changes have occurred and take measures to mitigate them. Ultimately, you are ensuring safety - whether it is personal safety or public safety, it depends on the application.

In order to control the operation of large mechanical processes such as pumps, conveyors, compressors, heaters, etc., accurate readings must be obtained in real-time from closed-loop Hall current sensors. You must be able to obtain readings and then make appropriate responses. Current sensing has been found to be a more economical and reliable method for monitoring and controlling large power loads, leading to an exponential increase in demand for current sensors.Traditionally used to protect circuits from damage and general current reporting, current sensors are now more widely used. These measures include performance monitoring and enhancement; Prevent overcurrent, which can overload the circuit and put it in danger; And battery powered circuits, such as circuits with battery chargers. Rechargeable batteries can particularly benefit from current sensing, as without measuring current, they can easily become overloaded or otherwise useless.

The range of closed-loop Hall current sensors (including AC current sensors) provided covers almost all configurations that may be required in multiple industries. The commonly used AC current sensors search for AC current input, usually with AC voltage output. Although this configuration can be changed in various ways according to your needs, it is important to understand what you need to monitor and what kind of output sensors need to display for you. 閉環型霍爾電流傳感器The working principle is to connect to a live wire. Once connected to the circuit, the sensor will read the current passing through the circuit when passing through the resistor. A resistor is a device placed on the current path that obstructs the flow of current, typically used to control and pass the amount of current through a circuit. The voltage will decrease correspondingly when passing through the resistor, depending on the overall level of the resistor; By measuring the proportion of this decrease, the sensor can calculate the overall current of the circuit.
