Bi-directional differential pressure sensor for when ultra-low pressure performance is required

The MDP200 from MEMSIC, Inc. is a Bi-Directional Differential Pressure Sensor. RoHS and REACH compliant, it is for CPAP, breath detection, room pressure, damper control, flow hood, fume hood, filter monitoring, and other applications where ultra-low differential pressure performance is required.

Leveraging its thermal accelerometer technology and experience in consumer electronics, MEMSIC will be offering a high-performance differential pressure sensor for medical, HVAC, and other applications where ultra-low pressure performance is required.

The MDP200 pressure sensor is based upon the MEMS thermal accelerometer platform. This ultra-sensitive MEMs thermal technology enables the MDP200 to detect minute changes in flow induced by differential pressure. The suspended bridge microstructure inside the MDP200 allows it to reliably detect pressure changes from a range of 0.016 Pascal to 500 Pascal.

The MDP200 series differential pressure sensors measure ultra-low gas pressures covering the range of up to ±500Pa (±2 inH2O) with a wide dynamic range, long-term stability, and repeatability and hysteresis. The MDP200 is also available as a low cost flow detector with an analog output and can be configured to suit a variety of applications, including medical CPAP and ventilator, HVAC and building control, burner control, and process control and automation.

“No diaphragm type sensor can achieve this level of performance,” says Ohlan Silpachai, Flow Product Manager at MEMSIC. “We compared our MDP200 against a class leading competitor differential pressure sensor with a 0″ to 0.1″ water column (25 Pascal) output range. In this head to head test, Memsic’s MDP200 demonstrated a superior signal to noise ratio at signal levels below 1 Pa, while offering a full-scale range of 20x higher (MDP200 is calibrated at +/-500 Pa). The integrated electronics within the sensor chip allows a 16 bit digital I2C output at an update rate of less than 7 ms.”
