Product Description

The CMF5032 gas mass flow sensor utilizes a micro-electromechanical system (MEMS) flow sensor chip, suitable for various applications involving clean and relatively dry small-flow gas measurement and process control. The unique packaging technology allows the product to meet different flow measurement ranges, ensuring high sensitivity, high reliability, high stability, and low cost.

The CMF5032 series is based on the MEMS flow sensing unit and a high-precision digital processing and calibration circuit (MCU). The integrated Δ-Σ A/D converter and the logic circuit, along with the MCU processor with internal calibration functions, ensure real-time effective acquisition of sensing signals and accurate flow signals. This internal compensation algorithm processing eliminates the need for external calibration compensation, ensuring high accuracy flow output. The friendly digital output communication allows users to easily obtain relevant data information. The product has a very broad application range.
