Use a magnetically biased Hall-effect integrated circuit to accurately sense movement of ferrous metal targets.
The uniquely designed IC (integrated circuit) and a permanent magnet are sealed in rugged, probe-type packages.
The flux density of the permanent magnet alters when approached by ferrous metal and is detected by the Hall ICs. If the sensor is positioned at the circumference of a revolving gear wheel, for example, it detects the teeth and tooth spaces, supplying a digital pulse output with frequency proportional to gear wheel speed. Potential applications include tachometers/counters, speed of gears and shafts in transmissions, hydraulic motors, pumps, and gear boxes flow meters/turbines, and engine RPM.
