The Hall rotation speed sensor is installed at the speed measuring end, which senses the convex teeth or concave grooves on the guide magnet, and correspondingly gives the high and low level, which is used to detect the speed and linear speed of the wheel axle. The acceleration of the measured body can also be obtained through calculation and processing.

Hall rotation speed sensor has good low frequency and high frequency characteristics. Low frequency can be up to 0Hz, which can be used for zero speed measurement of rotating machinery; high frequency can be up to 20kHz, which can meet the high speed measurement requirements of most industrial fields.

No contact between the sensor and the gear under test, no wear, easy to install, the output waveform is square wave.

Hall rotation speed sensor has the characteristics of wide speed measurement range, wide temperature adaptation range and strong vibration resistance.
