Description
S400A G1 DN25 1inch 1-60L/min 3.5-24V Water Flow Sensor Product Features: 1, the product appearance of lightweight flexible, small size, easy to install. 2, the impeller is rotated around the whole root of stainless steel bearings, stainless steel beads embedded rotating improve sensitivity. 3, seal with, the structure of the force under the influence of thermal expansion and contraction that never leaks. 4, the Hall element imported, and water isolation design, epoxy resin, oxidation. 5, all raw materials are in line with ROHS testing standards 6, porous design of small flow can be sensed as usual. I. Introduction: Water flow sensor consists of a plastic body, the flow of the rotor assembly and a Hall sensor. It is installed in the water heater inlet end for detecting the flow of water when the water flow through the rotor assembly, A magnetic rotor and the flow speed is adapted to change, the Hall sensor output corresponding pulse Signal feedback to the controller, the controller is determined by the size of the water traffic regulation. Caution: Non-violent shocks and chemical erosion. Prohibited throw or collision. Medium temperature should not exceed 120 degrees Second, lead the way: IN 1 red then positive 2 yellow OUT NPN output signal line 3 black GND to negative Frequency: F = 4.8 * Q (L / Min) error: ± 2% of flow rate for the column with 1L is 4.8 * 1 * 60 is equivalent to the number of pulses flowing through the voltage output of the premium: 3.5-24VDC, current can not exceed 10mA, a liter of water flow after pulse output 288 That frequency calculation unit * = constant flow rate (L / min) * Time (seconds) Flow range: 1-60L / min Fourth, the technical parameters
Scope: Apply to food, credit card machines, water vending machines, and other flow measurement devices! Basic parameters: 1, the lowest rated working voltage DC4.5 2, the maximum operating current 15 mA (DC 5V) 3, the working voltage range DC 5 ~ 24 V 4, load capacity ≤10 mA (DC 5V) 5, temperature range ≤80 ℃ 6, Operating humidity 35% ~ 90% RH (no condensation state) 7, allowing pressure The following pressure 1.75Mpa 8, the storage temperature -25 ~ + 80 ℃ 9, storage humidity 25% ~ 95% RH
