■ Introduction The FSF-S2 series fow switch is a small fow switch suitable for measuring small changes in fow in a pipe. t converts the changes in the fow sensed into the pipeline into electrical signals, and the fow in the pipeline is automatically controlled by the actuator. It uses a highly sensitive micro switch to ensure that the fow switch has high reliability, high sensitivity and fast transient action. ■ Technical Parameters ● Ambient temperature: -20~+65°C ● Medium temperature: -20~+110°C ● Maximum fuid pressure: 1.5MPa ● Electrical rating: DC 100V 0.5A 10W ● Maximum allowable fow rate: 3 m/s ● Applicable medium: Does not erode plastic fuid ● Protection level: IP65 ■ Type & data
