1.1Introduction
The S400 series is fabricated using a micro-electromechanical system (MEMS) flow sensor chip. It is suitable for the measurement of clean and relatively dry gases for various purposes. It realizes the digitization, intelligence and high safety of the equipment, and has the innovation of traditional industries. Function and improvement; a wide range of flow ranges meet the flow measurement requirements of different equipment in the industry. High sensitivity, high reliability, high stability and low cost performance characteristics can promote the industry to develop energy-saving and intelligent.
The S400 series is based on a MEMS flow sensing unit, high-precision digital processing and calibration circuit (MCU), integrated high-resolution delta-sigma A/D converter and logic with internal calibration and MCU processor. The sensing signal is effectively collected in real time, and the accurate flow signal is obtained, and the corresponding compensation algorithm is processed internally, so that no external calibration compensation is required, and high-precision flow output can be ensured; the friendly digital output communication mode can be used by the user. It is very convenient to get the corresponding data information; the product application range is very broad.
