The BP20L monocrystalline silicon pressure core series adopts MEMS monocrystalline silicon pressure chips imported from Germany, achieving internationally leading overvoltage performance and ensuring excellent signal stability. Assembled using a fully welded sealing structure and filled with silicone oil under high vacuum, measuring diaphragms of different materials not only isolate the measured medium from the pressure chip, but also enable the sensor to reliably measure the pressure difference signals of various highly corrosive media for a long time. This product applies the measured pressure directly to the diaphragm of the sensor, causing the diaphragm to produce a micro displacement proportional to the pressure. The integrated electronic circuit detects this change and converts it into a standard measurement signal corresponding to the pressure.
