Feature: 1. This flow switch is a sensor equippment that converts water flow into a switch-type electrical signal when a certain flow rate is reached. 2. Water flow sensor is composed of magnetic core, return spring, forged copper or polycarbon shell and sensor. 3. With shell made of PP plastic, the magnetic core is made of NdFeB permanent magnet material, and the sensor magnetic control switch is an imported medium power component. 4. And the inlet and outlet ports are G1 / 2 standard pipe thread, which is practical to use. 5. Meanwhile, such kind of flow switch has the advantages of high sensitivity and strong durability. Specification: Item Type: Water flow switch Model: FS-135 Interface Thread Size: both internal and external threads are G1 / 2 Material: PP plastic Working Voltage: DC0-110V Working Current: 0.5-1A Medium Proportion: 0.7 Signal Output Load: DC24V / 0.5A, 36V / 0.5A Suitable Ambient Temperature: ≥1 ℃ Suitable Working Temperature: ≤100 ℃ Minimum Starting Flow: ≥0.75L / min Maximum Flow Rate: ≤5L / min Rated Working Pressure: ≤0.65Mpa Maximum Pressure of Shell: ≤1.5Mpa Working Principle: when the water flow in the pipeline is more than 0.75L / min flow, the magnetic core generates displacement under the action of the water flow and drives the magnetic source to produce a magnetic control function to make the sensor output a "1" switch signal, which is input to the equipment control system, and after the power expansion and amplification, the purpose of water flow control is achieved. When the water flow in the pipeline is less than 0.75L / min flow, the magnetic core drives the magnetic source to return under the thrust of the return spring, so that the sensor outputs a "0" switch signal to stop the system. Adaptation Scope and Conditions: (1) The ambient temperature is not lower than 0 ℃. Do not knock on the casing. Keep away from magnetic objects. (2) The output of the signal is the switch quantity, so the connection mode of the control object must also be the switch control relationship. (3) The power of the controlled object shall not be more powerful than the signal load capacity. (4) This equipment is a water medium control equipment and cannot be used for other medium control. .
