New Series ■ Compatible with fans of sizes 80 to φ400 mm. Alarm output when the fan's rotation speed falls below the specified value.
It constantly monitors the rotation speed of the fan motor and outputs an alarm signal when abnormal rotation occurs (a decrease below the specified rotation speed or a reduction in rotation due to external forces). The metal blade type fan motor has a magnet and a pickup coil mounted on the side of the outer casing, detecting disturbances in the magnetic field generated when the metal blades pass by, producing an alternating current signal proportional to the rotation speed, and outputting an alarm when the speed drops below the specified level. It detects abnormalities in the fan motor of the system you are using, its wiring system, the power supply unit, and a decrease in the system's cooling capacity.
