ceramic base

Ceramic Sensor Base is precision‑manufactured advanced alumina ceramic substrate, serving as the core insulating and supporting base for various sensors such as oxygen sensors, pressure sensors, temperature sensors and automotive sensing components.Made of high‑purity alumina ceramic (95% /99% /99.5% Al₂O₃), this ceramic base delivers outstanding electrical insulation, excellent thermal shock resistance, high mechanical strength and chemical inertness. It remains stable under high‑temperature, corrosive and heavy‑vibration working conditions, protecting internal sensing elements and electrodes, ensuring consistent signal transmission and long‑term measuring accuracy.   High‑precision dimensional tolerance is achieved via advanced dry‑pressing and green‑body machining. Custom holes, slots and electrode printing patterns are available according to customer drawings. Good sealing performance supports glass‑to‑metal sealing assembly for sensor packaging.
