Description: Features:Minimum rated operating voltage: DC 5V-24V Maximum operating current: 15mA (DC 5V)Operating voltage range: DC 5 - 18V Load capacity: le; 10mA (DC 5V)Operating temperature range: le; 80°cHumidity Range: 35% to 90%RH (no frost)Permissible Withstand Pressure: Water pressure below 1.75 MPaStorage Temperature: -25 - +80° Humidity Storage: 25% to 95% RH High Output Pulse Level: gt; DC 4.5 V (DC 5 V input voltage)Output pulse low: Accuracy (flow-pulse output): 10 - 300L/min ± 3%Output pulse duty cycle: 50 ± 10%Output rise time: 0.04mu; sExit fall time: 0.18mu; sFlow pulse characteristics: horizontal test pulse frequency (Hz) = [0.2 * Q] ± 3% (level test) (Q is the flow rate L/min)Impact resistance: the product is well packed, free from 50cm height X, Y, Z direction to the concrete surface without abnormality, the accuracy varies within 5%. Insulation resistance: the insulation resistance between the hall sensor and the copper valve body is 100 MOmega; or more. (DC 500V)Heat resistance: placed in an environment of 80 ± 3 °C for 48 hours, returning to normal temperature for 1-2h without abnormality, and the parts have no cracks, backlash, expansion, deformation, etc., and the accuracy varies within 10%. Cold resistance: placed in the environment-20 ± 3 °C for 48 hours, returned to normal temperature for 1-2h without abnormality, and the parts have no cracks, clearance, expansion, deformation, etc., and the accuracy varies within 10%. Moisture resistance: when taken out for 72 hours in an environment of 40 ± 2 °c and 90% to 95% relative humidity, the insulation resistance is 1 MOmega; or more. Pulling force: applying 10N pulling force for 1 minute on the power cord, no backlash or breakage, and no change in performance. Durability: at normal temperature, 0.1mpa water pressure is input from the water inlet to turn on 1S, and 0.5S is off.
