TUV and UL certified fan sensor (rotation anomaly detector) with international standards.

Our company handles a "sensor for metal blade fans" that constantly monitors the rotation speed of the fan motor and outputs an alarm signal in the event of abnormal rotation (a decrease below the specified rotation speed or a decrease in rotation due to external forces). Since it is electrically separated and insulated from the fan motor, it reliably outputs alarms without being affected by abnormalities occurring on the fan motor side. Additionally, because the fan motor and sensor are certified as a set, it enables the construction of a system with high reliability, high safety, and high insulation. 【Features】 ■ TUV certified and UL certified products ■ Equipped with high insulation resistance ■ Same dimensions as general-purpose fan sensors ■ Relay contact output type has reinforced insulation between input and output ■ All models have built-in current fuses, etc. *For more details, please download the PDF or feel free to contact us.
