KEYENCE FD-X Series Clamp-On Micro Flow Sensor
The KEYENCE FD-X Series offers a revolutionary approach to monitoring micro liquid flow, providing accurate and reliable measurements without direct contact with the fluid.
Mount and Monitor Micro Flow in Seconds
The FD-X Series enables quick and easy installation, allowing users to mount and start monitoring micro flow rates in seconds. Its clamp-on design ensures no impact on the process, making it ideal for a wide range of applications.
Key Benefit: CLAMP-ON to Monitor Micro Flow Anywhere.
Key Features
Hassle-Free Design
- No Impact on Process: The clamp-on design fits securely around the pipe or tube without any impedance of flow.
- No Clogging: Unlike conventional sensors, the FD-X Series does not contact the liquid, preventing clogs.
- No Pressure Loss: Designed to prevent any pressure loss, crucial for micro flow applications.
- No Pipe Modification Necessary: Eliminates the time and cost associated with system modifications.
- No Special Tools Required: Installation requires only a Phillips-head screwdriver.
- No Maintenance: Virtually eliminates the need for maintenance due to its non-contact nature.
Unmatched Detection
- Micro Flow Detection: Capable of detecting very low flows, from a drop of water to small sprays.
- High Repeatability: Achieves high accuracy, e.g., ±0.1% of F.S. for instantaneous flow and ±0.003 mL for shot amounts.
- Fast Response Time: Offers one of the industry's fastest response times at 50 ms.
- Easy Bubble Detection: Specialized mode to prevent bubbles from damaging the system.
- Highly Visible Indicator: Provides clear visual feedback on flow status (OK, Approaching Limit, Alert).
Utilize Everywhere
- Any Application: Suitable for diverse industrial processes.
- Any Liquid: Detects viscous, corrosive, and sanitary liquids.
- Any Tube/Pipe: Compatible with plastic, rubber, and metal pipes ranging from Ø3 mm to 14 mm (0.12" to 0.55").
- Any Space: Impressively small sensor heads fit into tight spaces.
- Any Environment: Superior environmental resistance (IP68G, Chemical Resistant) for use with water, oil, and chemicals.
Applications
The FD-X Series is versatile and applicable across numerous industries and processes:
- Spraying/Coating: Monitor for clogs in spraying lines and ensure proper liquid application (e.g., release agent for molds/dies, coating spray confirmation).
- Filling/Injecting: Ensure the appropriate amount of liquid passes through the system (e.g., proper chemical mixing, product filling).
- Dispensing: Confirm the proper amount of liquid is dispensed or applied (e.g., sealant dispensing, specialized liquid application).
- Cooling/Lubricating: Monitor cooling and lubricating lines to prevent overheating or damage (e.g., chiller flow confirmation, part lubrication monitoring).
Connectivity and Control
- Quick Data Retrieval: Continuously records liquid usage data, viewable on the amplifier or exportable to a PC via USB.
- Network Compatibility: Supports various network platforms including EtherNet/IP™, EtherCAT, DeviceNet, CC-Link, and IO-Link.
- FS-MC8N/P Compatibility: Allows controller settings to be saved and loaded for easier troubleshooting and replacement.
- Easy to Use Controller: Features intuitive displays, push-button calibration, and an easy-to-navigate menu structure for quick setup and operation.
- Intuitive Displays: OLED screens provide various display options, including graphs of flow rates or shot amounts for trend recognition.
- Simulation Mode: Allows checking outputs without actually changing the flow rate.
Operating Principles
- Delta TOF (Time of Flight): Improves upon conventional ultrasonic methods by simultaneously monitoring two signals (one with flow, one against flow) for consistent and stable readings, unaffected by external factors like clogging or temperature changes.
- Automatic Power Control: Adjusts signal strength to ensure stable detection across various pipe materials, from steel to rubber.
- Accumulated Signal Processing: Bases detection on multiple signal transmissions to combine signals and ignore external noise.
- Guided Wave Technology: Innovative noise reduction technique that prevents signal interference.
