AI Technical Summary

Technical Problem

Existing integrated temperature and pressure sensors require numerous sealing structures because the temperature sensor is placed as a separate component on the ceramic core near the fluid being measured. This increases production costs and leakage risks, and the assembly process is complex, affecting reliability and production efficiency.

Method used

High thermal conductivity ceramic is used as the pressure core, and the temperature sensor is directly integrated onto the ceramic surface. It is then integrated with the circuit board through processes such as patching and sintering. Combined with magnetic fixation and multiple sealing designs, the electrical connection and sealing structure are simplified.

Benefits of technology

It significantly reduces production costs and leakage risks, improves measurement accuracy and assembly efficiency, extends service life, and ensures the continuity of signal transmission and overall reliability.
