Item Type: Plastic Water Flow Sensor Switch_x000D_ Model: Fs-1 / 2-nylon_x000D_ Interface Thread Size: Male/Female threads are G1/2in_x000D_ Material: Nylon_x000D_ Working Voltage: DC0-110V_x000D_ Working Current: 0.5-1A_x000D_ Medium Specific Gravity: 0.7_x000D_ Signal Output Load: DC24V/0.5A, 36V/0.5A_x000D_ Suitable Ambient Temperature: 1_x000D_ Suitable Working Temperature: 100_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_ Length: Approx. 64mm / 2.5in_x000D_ Working Principle: When the water flow in the pipeline is greater than 0.75L/min, the magnetic core is displaced under the action of the water flow and drives the magnetic source to generate a magnetron effect to cause the sensor to output a "1" switching signal, which is input to the equipment control system , After power 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, so that the sensor outputs a "0" switching signal to stop the system_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.
