Tips: Application of Hall effect current sensor in current monitoring of electric welding machine
In manufacturing, the real-time current monitoring data acquisition of electric welding machine needs to use current sensors. In the electric welding machine circuit, the specific position of the current sensor is in the inside of the electric welding machine, which can provide effective current monitoring for the electric welding machine. Many inverter welding machines use Hall effect current sensors.
The specific function of the current sensor in the electric welding machine is to detect the output current of the electric welding machine and pass the current sampling to the ammeter for display. Some current sensors need to transmit the current signal to the main control circuit, and the main control circuit stabilizes and adjusts the current shape according to the fluctuation. In the output feedback loop of the electric welding machine, this signal detection work of the current sensor is very important. If the current sensor is abnormal, it will cause the electric welding machine output current out of control, which will serious damage to the electric welding machine inverter device.
