About the MPM280Au Pressure sensor module
MPM280Au pressure sensing element is a measuring element specially developed for hydrogen measurement applications. The sensor is flat membrane structure and adopts gold plating techniques on the membrane to effectively prevent “hydrogen embrittlement" and "hydrogen penetration". It improves the working life of the sensor as well as ensure the site safety. MPM280Au pressure sensor selects the high-precision and high-stability diffusion silicon piezoresistive pressure sensitive chip produced by famous international manufacturer. The pressure
sensitive component is automatically tested by computer and fabricated with zero point correction and temperature
compensation. With high accuracy and good stability, it can be widely used in various hydrogen pressure measurement applications.
