Item Type: Water Flow Sensor Switch_x000D_ Model: FS G1/2 double male thread_x000D_ Working Voltage: DC0-210 (V)_x000D_ Working Current: 0.5-1 (A)_x000D_ Working Temperature: -10 ~ 85()_x000D_ Maximum Temperature Resistance: 85()_x000D_ Working Pressure: 0.2 (Mpa)_x000D_ Medium Specific Gravity: 0.7_x000D_ Thread Size: Double male thread G1/2_x000D_ Minimum Starting Flow: 0.75L / min_x000D_ Maximum Throughput: 5L / min_x000D_ Rated Working Pressure: 0.65Mpa_x000D_ Maximum Pressure of the Shell: 1.5Mpa_x000D_ Signal Output Load: DC24V/0.5A, 36V/0.5A or AC220V/0.1A_x000D_ Adaptation Scope and Conditions: _x000D_ (1) The ambient temperature is not lower than 0. Do not knock on the case. Keep away from magnetic objects._x000D_ (2) The output of the signal is a switch value, so the connection method of the control object must also be a switch control relationship._x000D_ (3) The power of the control object must not be greater than the signal load capacity._x000D_ (4) This device is a water medium control device and cannot be used for other medium control._x000D_ When the water flow in the pipeline is greater than 0.75L / min, the magnetic core will be displaced under the action of the water flow and drive the magnetic source to generate a magnetic control action to cause the sensor to output a "1" switching signal. After expansion and amplification, the purpose of water flow control is achieved. When the water flow in the pipeline is less than 0.75L / min, the magnetic core will drive the magnetic source back under the force of the return spring, causing the sensor to output a "0" switching signal to stop the system. Recommended for use with small relays
