The **F2VS-G3-R** is a specific sensor controller or flow sensor component, typically associated with industrial automation and fluid control systems (often manufactured by companies like **CKD**). It is designed to monitor and manage fluid flow (usually gas or air) with precision. --- ### 1. Key Electronic Specifications Below are the typical electronic characteristics for the F2VS series: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 12 to 24 VDC (±10% ripple) | | **Current Consumption** | Approx. 30mA or less | | **Output Type** | NPN or PNP Open Collector (model dependent) | | **Switch Output** | Max 30VDC, 80mA | | **Response Time** | Configurable (typically 5ms to 1000ms) | | **Protection Circuit** | Reverse polarity, Overcurrent, and Short-circuit protection | --- ### 2. Core Electronic Components The internal architecture of the F2VS-G3-R consists of several critical electronic stages: 1. **Thermal Flow Sensing Element:** * Uses a MEMS (Micro-Electro-Mechanical System) chip. * It measures flow based on the heat transfer principle (cooling effect of the gas moving over a heated element). 2. **Analog-to-Digital Converter (ADC):** * Converts the analog voltage from the thermal sensor into a high-resolution digital signal for the microprocessor. 3. **Microcontroller (MCU):** * Processes the flow data, handles the LED display logic, and manages the user-defined threshold settings. 4. **Signal Output Stage:** * Uses transistors (NPN/PNP) to provide digital switching signals to a PLC (Programmable Logic Controller). --- ### 3. Wiring Diagram Logic To integrate the F2VS-G3-R into a circuit, the wiring generally follows this standard color code: | Wire Color | Function | Description | | :--- | :--- | :--- | | **Brown** | V+ | Power supply positive (12-24V) | | **Blue** | 0V | Power supply negative/ground | | **Black** | Out 1 | Control output (Switching signal) | | **White** | Out 2 / Analog | Secondary output or 1-5V Analog signal | --- ### 4. Functional Features * **Dual Display:** Usually features a 2-color digital display to indicate current flow and set values simultaneously. * **Hysteresis Mode:** Allows the electronics to prevent "chattering" by setting different points for the switch to turn ON and OFF. * **Accumulated Flow:** The internal memory can track the total volume of gas passed over time.
