DETAILS

BAFS3000 GAS FLOW SENSOR

DESCRIPTION:

       BAFS3000 series mass gas flow sensor is made of micro-electro-mechanical system (MEMS) flow sensor chip, which is suitable for clean, relatively dry, low-flow gas measurement and process control for various purposes. The unique packaging technology enables the product to meet different ranges of flow. measurement, ensuring high sensitivity, high reliability, high stability and low cost.Accurate flow signal is obtained, and the corresponding compensation algorithm is processed internally, so there is no need to do any external calibration compensation to ensure high-precision flow output;

CHARACTERISTICS:

  • High accuracy (1.5% F.S accuracy)

  • Linear output and no temperature compensation required

  • Long-term stability with minimal zero drift

  • Solid-state sensing core (no surface voids or fragile membranes), resistant to clogging and pressure shocks

  • Fast response time (1ms response time)

  • Wide flow range 0sccm -2000sccm

  • Able to adapt to relatively humid gas measurement
