YF-G21 G1/2 DN15 4 Lines With Temperature Sensor Water Flow Sensor

YF-G21 G1 / 2 DN15 4 Lines With Temperature Sensor Water Flow Sensor YF-G21 G1 / 2 DN15 4-wire temperature sensor with water flow sensor Features: 1, the product looks lightweight and flexible, small size, easy installation. 2, impeller lined stainless steel, stainless steel beads will 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 120 ℃. Second, lead the way: ? ? IN 1 red, then positive 2 yellow OUT signal output line 3 black GND to negative 4 green resistance (3950K 50K) Frequency: F = 8.1 * Q (L / min) -3 Error: ± 2% Voltage: 3.5-24VDC, the current can not exceed 10mA, the end of the flow output 483L of water a pulse Constant Frequency Calculation = 8.1 * Unit Flow (L / min) * Time (Seconds) -3 Flow range: 1-30L / min Third, the technical parameters Scope of application: For food, credit card machines, vending machines and other flow measurement equipment! ???Basic parameters 1, the lowest rated voltage DC4.5 5V-24V 2, the maximum operating current 15 mA (DC 5V) 3, the working voltage range DC 5 ~ 18 V 4, load capacity ≤10mA (DC 5V) 5, the temperature range ≤80 ℃ 6, working humidity 35% ~ 90% RH (no condensation) 7, to allow pressure The following pressure 1.75Mpa 8, storage temperature -25 ~ + 80 ° C 9, storage humidity 25% ~ 95% RH
