A hall current sensor produces voltage by means of the "hall effect". It is used in automobile applications such as wheel speed sensors, tachometers, speedometers and ignition.
The hall sensor can be found on top of a Volkswagen Passat engine. The sensor is placed under the valve cover next to the timing belt.
It doesn't have a hall chip or a hall effect sensor, it has an inductive pulse cam/crank sensor. You can clean those.
yes, located in the distributer.
As magnets pass a filed they cause a deflection a hall sensor will detect that
No.
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879
a current flow close to a magnetic source it influence the sources hall effect is a disturbed signal as a function of speed.
this sensor is inside the distrib.
heat, primarily. either causing degausing of the permanant magnet behind the sensor, or other thermal damage to the hall ic itself.
A hall effect sensor is a sensor that produces a square wave output that can be directly read and modulated by the ECM (as opposed to an AC wave sensor which produces a sine wave that must be converted). They are used as cam position sensors and ABS wheel speed sensors
Typical household GFIs are designed using cheap magnetics which would saturate given a DC leakage current. This means it will not be sensitive to a slow changing DC leakage current. a DC GFI can be made and does exist, but it will require a sensor that can sense DC flux without being saturated, such as a hall effect sensor chip.
in the distributor in the rear of the engine. sometimes known as a hall sensor
