Магнитный датчик скорости Caterpillar 4925674

The Magnetic Speed Sensor is a sensing mechanism to detect the rotational speed of the fan motor. The magnetic sensor, a magnet is attached to the rotating fan motor shaft, and the sensor detects the changes in the magnetic field as the shaft rotates. An optical sensor, a light source, and a photodetector are used to detect the interruptions caused by the rotating fan motor, thereby determining the speed.Attributes:• Provided with Coil resistance range from 135 - 165 ohms• Provides surface speed of 628.3 IN/s with 120 number of gear teeth on sensing wheelApplications:The Magnetic Speed Sensor is used to contribute to the safe and efficient operation of machines and equipment by providing accurate speed measurements and enabling precise control of the fan motor.
