In the wave of rapid development of modern technology, the demand for precise monitoring of small pressure changes is increasing in many industries, whether it is fire protection systems related to life safety, medical equipment such as ventilators that require high precision, or HVAC purification systems that pursue high efficiency and energy conservation. In the field of industrial control, sometimes a measurement deviation of 1Pa may result in a loss of tens of millions of yuan in the production of products, and the demand for 0.1Pa micro differential pressure resolution in high-end equipment is becoming increasingly common. Therefore, how to accurately measure micro differential pressure within+125Pa has become a key factor in improving product performance and safety. In this context, the DWSCD series MEMS micro differential pressure sensor, innovatively developed by the Duwei Intelligent MEMS Intelligent Sensor Technology Research and Development Center, has made a strong debut with numerous advantages such as zero point super stability and measurement accuracy better than 1%. Like a shining star, it shines brightly in the field of micro differential pressure measurement, especially in its excellent performance in measuring small ranges of 0-25Pa, ± 50Pa, and 0-60Pa, setting a new benchmark in the industry.
