New Series Rotational Speed Detection Sensor Fan
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.
basic information
Features: - Alarm output when the fan motor's rotation speed is below the specified level. - The sensor circuit is electrically isolated from the fan motor, ensuring it is not affected by abnormalities occurring on the fan motor side. Types: - With or without output delay timer upon power-on. - Normally open, normally closed. Output: - Relay contact output type. - Open collector output type. Power Supply: - DC power supply: Relay contact type - DC24V, Open collector type - DC5 to 24V. - AC power supply: Same voltage as the fan power supply.
