Description
Based on piezoresistive silicon technology, PS19D is manufactured from imported piezoresistive silicon dies. The measured pressure is transmitted to the piezoresistive silicon sensing element through 316L isolated diaphragm and internal medium, thus to realize the precise transformation of electrical signal from pressure. This isolation enables the sensor to measure the pressures of corrosive fluids as well as electro conductive liquids.
This sensor is tested by computer automatically, and is compensated by laser trimming for zero and
sensitivity. Its profile and assembly size have good interchangeability with some Europe general products.
PS19D is widely used for differential pressure measurement in many industrial process control areas with perfect long term stability.
