LFS11 Low Air Velocity Transmitter is designed for accurate measurement of very low air velocity, and still has high measurement accuracy in application where air velocity is less than 0.15m/s. LFS11 uses a high-quality hot film sensor manufactured based on MEMS technology, which has the characteristics of high measurement accuracy, good stability and strong environmental adaptability, which is ideal for laminar flow monitoring and special ventilation applications, mainly used in key environments such as medical institutions, laboratories, and pharmaceutical industry.
Features
* Adopt imported high-precision MEMS sensor, long-term stability and anti-interference capability.
* Power supply and output has overload and reversed-connection function.
* lsolated output Optional.
* Strong anti-pollution ability, easy to install and maintain.
