Speed sensor definition
The speed sensor is made up of a magneto-sensitive resistor as an inductive component and is a new type of speed sensor. The core component uses a magnetoresistive resistor as the sensing component, and the new signal processing circuit reduces the noise and improves the function. By comparing with the output waveform of other types of tooth speed sensors, the measured error of the rotation speed is extremely small and the linear characteristics are very consistent. The sensing object is magnetic material or magnetic conductive material such as magnetic steel, iron and electrical steel. When the object is magnetized or magnetized with protrusions (or depressions), as the object is rotated, the sensor outputs a pulse signal related to the rotation frequency to achieve the purpose of detecting the speed or displacement.
