Product overview:
X19 Industrial Pressure Sensor is the core component for the manufacture of pressure sensors and pressure transmitters. As high-performance
pressure sensitive component, X19 can be easily amplified and assembled into the pressure transmitters with standard signal output.
X19 packages diffused silicon pressure sensitive die to 316L stainless steel housing. The external pressure is applied directly to the sensor chip,
and the back of the sensor chip is compressed to form an all-solid structure for pressure measurement, so the product can only be used to measure clean,
non-corrosive gases, or liquids.
