X19-F Micro-Pressure Sensor
Product overview
The X19-F Micro-Pressure Sensor is the core component for manufacturing pressure sensors and pressure transmitters. As a small-range and high-performance pressure-sensitive component, it can easily amplify signals and be assembled into pressure transmitters with standard signal output.
X19-F seals diffusion silicon pressure sensitive die to 316L stainless steel housing. The external pressure is applied directly to the back of the sensor chip, forming an all-solid structure for pressure measurement. Therefore, this product can only be used to measure clean, non-corrosive gases.X19-F uses an O-ring for pressure sealing, making installation easy.
Our company can also undertake special customizations to meet users’ requirements, such as pressure sensors with a fully welded structure, wide temperature compensation, and high reliability.
