Boasting outstanding thermal stability, creep resistance and mechanical rigidity, the alumina ceramic substrate enables a wide operating temperature range from -40℃ to 150℃. It exhibits minimal long-term drift under repeated high-low temperature cycling and delivers superior long-term measurement stability. The ceramic base features excellent resistance to acid, alkali and medium corrosion, compatible with refrigerants, chemical fluids, pharmaceutical liquids, wastewater and other corrosive media. It covers a broader medium compatibility range and offers a longer service life than conventional diffused silicon sensor cores.
Thanks to its exceptional corrosion resistance, this ceramic core holds prominent advantages in refrigeration, chemical, pharmaceutical, environmental protection and other industries, gradually replacing mainstream diffused silicon pressure sensors.
