WebAug 12, 2016 · No, a 250ohm resistor is used to generate 5volt (with 20mA sensor current) for a 5volt A/D. If you want 3.3volt across the sense resistor with 20mA sensor current, you would pick a 3.3 / 0.02 = 165ohm resistor. Only the correct value shunt resistor uses the full range of the A/D. Protection is a different story. WebIt is also possible to connect a shunt resistor within the circuit itself and directly measure the current, as in the classic ammeter and current shunt. We will look at both methods in the sections that follow. Open loop vs. closed loop current sensors. You may hear about the open-loop and closed-loop current sensors.

WebFor this example, we will assume that a 0 to 2 Vdc input will be used to measure 4 to 20 mA. Ohms law states: R=V/I where V is the Voltage, I is the current and R is the resistance. R=2V/0.020A = 100Ω. When 20 mA flows through a 100Ω resistor, it will drop 2 volts. When 4 mA flows through a 100Ω resistor, it will drop 0.4 volts. WebJul 25, 2024 · An open-loop configuration is usually expected to exhibit a faster response time. Note that the offset of the Hall sensor can contribute to errors both in closed-loop and open-loop configurations. The offset of a quality indium antimonide (InSb) Hall element is typically ±7 mV.
