YF-S402B G1/4 PE Pipe 0.2-8L/min 3.5－12VDC Water Flow Sensor

YF-S402B G1 / 4 PE tube 0.2-8L / min 3.5-12VDC water flow sensor Features: 1, the product looks lightweight and flexible, small size, easy installation. 2, impeller inlaid stainless steel beads, never wear. 3, the seal structure of the force will not leak. 4, Hall components imported from Germany, and encapsulated with potting to prevent moisture, never aging. 5, all raw materials are in line with ROHS testing standards First, the introduction: Water flow sensor from the plastic body, rotor assembly flow and Hall sensor. It is installed at the inlet of the water heater to detect water flow through the rotor assembly, A magnetic rotor and flow rate to adapt to changes in the corresponding Hall sensor output pulse The signal is fed back to the controller, which depends on the size of the water traffic control. Be careful: Non-violent shocks and chemical attacks. Do not throw or crash. Vertical installation angle does not exceed 5 degrees. Medium temperature should not exceed 100 °. Second, to lead the way: IN 1 red, then positive 2 yellow OUT signal output line 3 black GND negative Third, the technical parameters ? 1 start water flow: <0.2L / min (L / min) 2 start water pressure: <0.1Mpa (MPa) 3 Working flow range: 0.2-8L / min (L / min) Pay attention to the output signal should not be higher than 150HZ 4, with clean air impeller residual water, idle time should be less than 30 seconds. 5 to withstand the maximum pressure; 0.8Mpa (MPa) 6 Operating voltage range: 3.5-12VDC (DC voltage) VDC 7 Working Current: 0.5-1.5mA (mA) 8 Operating temperature: 1-100 ℃ (degrees Celsius) 9 Ambient temperature: -40-100 ℃ Celsius) 10 Output Characteristics: [32 * Q] Q is the flow rate L / minHz (Hz) error ± 3% 11 Life: 106H (h) 5VDC1mA 12 Electrical Strength:> 600VAC (AC Voltage) Leakage Current 3mA Duration 5S Insulation resistance:> 100mΩ (megaohm) and the valve housing insulation resistance or
