Current shunt vs hall effect sensor
WebThe shunt sensor’s output is measured by the data acquisition system, which applies Ohm’s law to determine the amperage flowing through the circuit. ... Typical Hall Effect … WebMar 26, 2012 · For 2.5 A, I would say to use a resistor. With much larger motors, the power loss with a resistor can get very large and then a hall sensor is worth the money. To keep the power loss low, you want to keep the voltage across the resistor small. Therefore I feel it is better to use a comparator or the DAC on the PIC.
Current shunt vs hall effect sensor
Did you know?
WebHall effect current sensors are widely used because they provide a non-intrusive measurement and are available in a small IC package that combines the sensor and signal-conditioning circuit. Current-sensing transformers are also a popular sensor technology, especially in high-current or AC line-monitoring applications. WebLEM is a leading supplier of current transducers (also called current sensors), offering a wide range of galvanically isolated transducers that have become industry standards. The broad range of sizes, measuring …
WebLEM Hall Effect current sensors are available in open-loop, closed-loop and Eta configurations. Open-loop Hall Effect sensors are highly cost effective, as well as being small and consuming minimal power. Closed-loop sensors offer higher accuracy and enhanced speed to enable currents with a wider range of frequencies to be measured.
