Numerous techniques and products are available for regulating fluid power. However, they all boil down to one of two concepts: open-loop control and closed-loop control. WebA closed-loop sensor has a coil that is actively driven to produce a magnetic field that opposes the field produced by the current being sensed. The Hall sensor is used as a null-detecting device, and the output signal is proportional to the current being driven into the coil, which is proportional to the current being measured. pappy bourbon 12 year
