Description
Based on piezoresistive silicon technology, Pressure sensor PS20 is manufactured from imported piezoresistive silicon dies. It is features of fully welded construction with a flush diaphragm .It able to measure pressure of viscous liquids. The measured pressure is transmitted to the piezoresistive silicon sensing element through 316L isolated diaphragm and inner medium, thus to realize the precise transformation of electrical signal from pressure.
PS20 pressure sensor is suitable for applications in medical, food and beverage industry.
