Hall effect current sensor with internal integrated circuit amplifier. 8 mm opening. Zero current output voltage is midway between the supply voltages that maintain a 4 to 8-volt differential. The non-zero current response is proportional to the voltage supplied and is linear to 60 amperes for this particular (25 A) device.
A Hall-effect magnetic field sensor is then used to measure the induced current with its output being directly proportional to the magnitude of the current flowing. In the simplest configuration, a Hall-effect magnetic field sensor can be placed adjacent to the conductor and its output measured but there are limitations.
The term ordinary Hall effect can be used to distinguish the effect described in the introduction from a related effect which occurs across a void or hole in a semiconductor or metal plate when current is injected via contacts that lie on the boundary or edge of the void. The charge then flows outside the void, within the metal or semiconductor ...
6 kW Hall thruster in operation at the NASA Jet Propulsion Laboratory. In spacecraft propulsion, a Hall-effect thruster (HET) is a type of ion thruster in which the propellant is accelerated by an electric field. Hall-effect thrusters (based on the discovery by Edwin Hall) are sometimes referred to as Hall thrusters or Hall-current thrusters.
Differential Hall Effect Metrology (DHEM) is an electrical depth profiling technique that measures all critical electrical parameters (resistivity, mobility and carriers) through an electrically active material at sub-nanometer depth resolution. [1] [2] DHEM is based on the previously developed Differential Hall Effect (DHE) method. [3]
Hall effect quadrature encoder, sensing gear teeth on the driveshaft of a robot vehicle. Mechanical: Also known as conductive encoders. A series of circumferential copper tracks etched onto a PCB is used to encode the information via contact brushes sensing the conductive areas. Mechanical encoders are economical but susceptible to mechanical wear.
