Product Description
High Performance Bi-Directional
Digital MEMS Gas Flow Sensor
MFC2000 Series
MFC2030/MFC2070 Digital MEMS Gas Flow Sensor DESCRIPTION
MFC2000 series is a new gas flow sensing module platform based on MEMSIC’s proprietary CMOS technology for thermal mass flow sensing. It can measure up to 70 SLM bi-directional flow rate with +/-3.0% accuracy.
The sensing element is monolithically integrated with CMOS signal processing circuitry and embedded software capable of converting gas flow rates to a digital or analog output with very high repeatability. The module has very low operating power consumption (<5 mA) and a low power consumption sleep mode (<100 µA) for optimal power management in portable applications. The MFC2000 series is externally powered, up to 5.5V (3.3V typ.). I2C digital output is standard. Other output available upon request.
