Resistive Current Sensing: Low-Side vs. High-Side Sensing

WebA resistor having a very low value of resistance such type of resistor is called shunt resistance. The shunt resistor is mainly made of the material having a low temperature coefficient of resistance. It is connected in parallel with the ammeter whose range is to be extended. It is also connected in series with the load whose current is to be measured. WebAs an example, a shunt resistor with a resistance of 1 mΩ is used as the series resistor in an ammeter. The resistor is placed in a circuit, and a voltage drop of 30 mV is measured across the resistor. This means that … csa offshoreWebIn this sense, a precision shunt resistor “converts” a current value into a proportional voltage value. Thus, current may be accurately measured by measuring voltage dropped across the shunt: Current measurement using a shunt resistor and voltmeter is particularly well-suited for applications involving particularly large magnitudes of current. dynasty youth football

"WebThe shunt voltage is limited to 25-mV max. This reduces power dissipation in the shunt to enable a high-current measurement range up to 200 A. Shunt voltage is amplified by an instrumentation amplifier configuration with a gain of 10 to match the input range of the isolation amplifier for better signal-to-noise ratio.
