Detailed Description
Summary of Product
The diffusion silicon pressure sensor of model QY1800 is a kind of silicon piezoresistive pressure sense organ using the advanced MEMS technology and integrating the modern information processing technology which is to convert pressure signal to standard voltage signal. The intelligentized compensation technology solved the inherent problem of silicon piezoresistive pressure sense organ on temperature drift, Which shows off the advantage of diffusion silicon pressure sensor.
