Wiegand sensor was invented in 1974, suitable for electronic water meter / calorimeter / gas meter / oil meter and other instruments.
Features of Wiegand Sensor
First, Wiegand sensor for passive components, work without additional working power.
Second, the magnetic pole to trigger the work, triggering a change in the magnetic field polarity, Wiegand sensor synchronous output of a positive and negative pulse signal, amplitude greater than 1V;
Third, the output signal amplitude and magnetic field has nothing to do with the rate of change, enabling "zero speed" sensor.
Fourth, non-contact, corrosion-resistant, moisture-proof, the service life of more than 2 billion times.
Fifth, Wiegand output signal can be used telephone lines, coaxial remote transmission.
Application of Wiegand Sensor
First, for the counting sensor, suitable for micro-power intelligent flow meter, such as electronic water meter / calorimeter / gas meter / oil meter.
Second, as an electronic switch, suitable for intelligent toys, access control and other automatic.
