In industries where precise airflow measurement is vital to operational efficiency, environmental control, and equipment performance, the LFS10 Air Velocity Transmitter stands out as a trusted, high-performance solution. Engineered with advanced MEMS technology and built for durability, this transmitter delivers consistent accuracy, easy integration, and strong adaptability—making it the ideal choice for HVAC systems, industrial pipelines, process control, and beyond.
Advanced Sensing Technology for Superior Performance
At the core of the LFS10 is an imported high-precision MEMS sensor, paired with a measurement principle based on heat conduction. This combination ensures exceptional long-term stability, strong anti-interference capability, and reliable performance even in dynamic environments. The transmitter offers flexible measurement ranges to suit diverse needs: 0-10m/s, 0-15m/s, 0-20m/s, and 0-30m/s (selectable via jumper for analog output versions).
Precision is a key strength: at 20°C, 45%RH, and 1013hPa, it achieves an accuracy of ±(0.2m/s + 3% of reading) and a resolution of 0.01m/s—providing granular, trustworthy data for critical decision-making. Whether monitoring air velocity in HVAC ducts, industrial pipelines, or environmental control systems, the LFS10 ensures you stay in control of airflow parameters.
Robust Design & Enhanced Protection
Built to withstand industrial demands, the LFS10 features a rugged construction that balances durability and practicality. The transmitter’s sheathing material is PC, with a Pa6 probe—offering resistance to pollution and wear. It boasts IP65 protection for the main unit and IP20 protection for the probe, shielding against dust, water splashes, and other environmental hazards.
The LFS10 also prioritizes operational safety: its power supply and output include overload and reversed-connection protection, preventing damage from incorrect wiring or voltage fluctuations. With a working temperature range of -10°C to +60°C and a storage temperature range of -20°C to +80°C, it adapts seamlessly to both indoor and industrial environments. Additionally, it meets EN61326-1 electromagnetic compatibility standards and holds ROHS and CE check here certifications (EU Electrical Safety Standards), ensuring compliance with global industrial regulations.
Flexible Configuration & Easy Integration
Designed for versatility, the LFS10 offers multiple customization options to fit diverse system requirements:
Output Modes: Choose from RS485/Modbus (digital) or 0~10VDC/4~20mA (3-wire analog), with isolated output available as an option. Output load compatibility is optimized: ≤500Ω for current mode and ≥5KΩ for voltage type.
Installation Types: Two variants cater to different setups—duct type for direct integration into air ducts and split type for flexible mounting in spaces where remote sensing is needed. The probe length is 210mm as standard (optional modifications available).
Display Option: Select between a model with an optional LCD display (equipped with unit indication and backlight) for real-time on-site monitoring or a display-free version for space-constrained or remote applications.
Installation and maintenance are hassle-free, thanks to the transmitter’s user-friendly design—reducing downtime and operational costs for your business.
