Reliable sensors for controlling marine diesel engines:

In the past, sensors for controlling marine diesel engines were laser-cut from a ceramic substrate. However, this process had major disadvantages: sharp edges were created that acted like predetermined breaking points. In addition, the connecting wires were soldered directly onto the ceramic. This had the disadvantage that these soldered joints came loose at high temperatures. The result: costly repairs to the ship’s diesel engines during the voyage. The previous supplier saw no market potential with the customer and discontinued the development of these parts.

Alumina Systems used the FEM method to calculate the thickness of the ceramic and pressed it. The connections were brazed. The result: the sensors can withstand high heat and high pressures. The ceramic no longer breaks and the contact wires no longer come loose during use. The marine engines run reliably and repairs due to broken ceramics or detached wires are a thing of the past.
