Sensor components made of High-Performance Ceramics
We manufacture high quality parts made from FRIALIT DEGUSSIT ceramics for applications involv-ing complex and demanding requirements. Sensor technology is an interesting, ever growing area often requiring the use of ceramics.
Analysers made from alumina oxide FRIALIT F99.7 for pressure sensors are today used for temperatures ranging from -50 to +150°C and for pressures up to several 100 bar (depending on the design). The membranes are manufactured at a thickness of 0.2 mm and measure up to 80 mm across. Glass or active soldering may be used to join the ceramic parts.
The materials for the electrodes are chosen in line with customer requirements. The analysers can be used in the oil & gas industry, chemical industry as well as in the petrochemical industry.
Other examples are microwave and radar sensors. For contact free orinterface measurements our ceramic products and solutions are used increasingly in sensor systems for media analysis as antennas, windows or microwave feedthroghs for level indication. Due to the optical features of alumina oxide material DEGUSSIT AL23hf, it is possible to focus microwaves more precisely, as when using other materials, such as glass or plastic. Miniaturization is made possible.
Ceramic components, like liners, with sintered in platinum electrodes for magnetically inductive flow meters, have been developed in close co-operation with our partners. These products provide precise measurement results and excellent reliability in applications such as found in offshore and subsea.
Another way of measuring is to use capacitive sensor principle. For level gauging systems, ceramic sensor components and sensor rings, also called water cut meters or multi phase meters (partially metalized and brazed), for a capacitive analysis of the ambient media are successfully applied in the offshore and subsea industry. These are used for pressure ranges of more than 1000 bar. Such systems allow for the exact determination of the proportion of different substances in liquid and gaseous media.
