Nanjing Wotian New Product—P20 Monocrystalline Silicon Pressure Core

From: Issued date 2021.05.11 Back

The P20 monocrystalline silicon pressure core series adopts MEMS monocrystalline silicon pressure chips imported from Germany to achieve international leading overvoltage performance and ensure excellent signal stability. It is assembled using a fully welded and sealed structure and filled with silicone oil under high vacuum. The measuring diaphragm of different materials can isolate the measured medium and the pressure chip while enabling the sensor to perform differential pressure signals of various strong corrosive media. Long-term reliable measurement.

The product is that the measured pressure directly acts on 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 and outputs a standard measurement signal corresponding to the pressure.
