Description: The generator rotate speed probe adopt electromagnetic induction principle, which can realize the speed measurement. A coil is wound around front end of the sensor. When the gear is rotated, the magnetic force line of the sensor coil changes. A periodic voltage is generated in the sensor coil, and the speed of the gear can be measured by counting the voltage.Therefore, the speed of the gears can measured. Features: The sensor housing is made of stainless steel, durable for use. Convenient installation and use. Easy to change when the sensor is missing or damaged, as a spare one to use. It can be used in bad environment such as smoke, oil and gas, water vapor, etc. Strong output signal, good anti-interference performance.
