This product uses a MEMS pressure sensor chip with a silicon silicon bonding structure, which is packaged on a circuit substrate through a special process. Complete medium isolation is achieved through vacuum oil filling technology, meeting the requirements for use in corrosive environments. After special process calibration and temperature compensation, the working IIC signal or voltage signal is output. It has the characteristics of small waveform coefficient, high reliability, excellent temperature resistance, and can be quickly assembled by customers Taobao official website: https://m.tb.cn/h.gixcy7wUC0fzDPz
