MDP200 Series MEMS Differential Pressure Sensors General Description
MEMSIC's MDP200 series MEMS differential pressure sensors measure ultra-low gas pressures covering the range of up to ±500Pa (±2 inH2O). The technology is based on MEMSIC's highly successful proprietary CMOS thermal accelerometers already sold in millions. MEMSIC's thermal flow sensing element is monolithically integrated with CMOS signal processing circuitry and embedded software capable of converting gas flow rates to a digital format. The signal is linearized and temperature compensated. 

MDP200 series offers a wide dynamic range, superb long-term stability, and outstanding repeatability and hysteresis. The MDP200 is also available as a low cost flow detector with an analog output and it can easily be configured to suit a variety of applications from burner control, HVAC, medical flow to industrial processing control.
