Pressure sensor suitable for medical and automotive applications

Leveraging its successful 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 competitively priced, highly reliable and ultra-low pressure performance is required.

The new MDP200 new pressure sensor is based upon MEMSIC’s advanced MEMS thermal accelerometer platform, with hundreds of millions of units successfully shipped into a diverse variety of real world automotive and consumer applications. This ultra-sensitive MEMs thermal technology enables the new 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 0.016-500Pa.

“No diaphragm type sensor can achieve this level of performance,” said Ohlan Silpachai, Flow Product Manager at MEMSIC. “We compared our MDP200 against a class leading competitor differential pressure sensor with a 0-0.1" water column (25Pa) output range. In this head to head test, Memsic’s MDP200 demonstrated a superior signal to noise ratio at signal levels below 1Pa, 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 7ms.”
