Accurate & fast response for power management. Series includes adjustable linear, null balance, digital, & linear current sensors. Closed loop sensors use feedback control to provide output proportional to measured current. A current sensor is a device that detects electric current in a wire and generates a signal proportional to that current. The generated signal could be analog voltage or current or a digital output.
The characteristics of this sensor are reliability, high resolution, a wide range of weak magnetic field measurements, and the magnetic field’s component direct measurement, These sensors are appropriate in high-speed motion systems. There are a variety of applications for current sensors. For example, some devices are used for power metering, control system diagnosis, current supply measurement, and the control of complex loads from electric motors. Others are used for charge integration and condition monitoring of rechargeable batteries.
When you connect a low ohm resistor in parallel with a circuit, the current flows through the shunt resistor -R- and generates a voltage drop. We can measure this drop and apply Ohm’s law to calculate the current. So if we know the voltage (drop) and resistance, we can calculate the current using I = V/R. There are 3 categories for cored current sensor; 1. Open-loop, 2. Closed-loop, and 3. Fluxgate.
