ShuntSensoren
ShuntSensoren are electronic devices used to measure electric current. They operate based on Ohm's law, which states that the voltage across a resistor is proportional to the current flowing through it. A shunt sensor consists of a low-resistance resistor, known as a shunt resistor, placed in series with the circuit where the current is to be measured. As current flows through the shunt resistor, a small voltage drop is generated across it. This voltage drop is directly proportional to the current. A voltage measuring device, such as a voltmeter or an analog-to-digital converter, is then used to measure this small voltage. By knowing the precise resistance of the shunt resistor and measuring the voltage drop, the current can be accurately calculated using the formula I = V/R, where I is the current, V is the voltage drop, and R is the resistance of the shunt. Shunt sensors are commonly used in applications requiring precise current monitoring, such as battery management systems, power supplies, electric vehicle powertrains, and industrial control systems. They are favored for their simplicity, accuracy, and relatively low cost. The accuracy of a shunt sensor depends on the tolerance of the shunt resistor and the precision of the voltage measurement. Different types of shunt sensors exist, varying in their resistance values, power handling capabilities, and output signal types.
