Description by Manufacturer

We have recently developed ceramic diaphragms for pressure sensors, the material used is aluminum 95% min, the shape and size of the ceramic ring, and the thickness of the ceramic diaphragm can be produced according to the customer’s design.

Physical properties of ceramic rings and ceramic diaphragms: Insulation, resistance to electrical breakdown, high temperature resistance, wear resistance, and high strength.

The ceramic pressure sensor uses a creep-free, rigid 95% AL2O3 ceramic diaphragm as the force-sensitive elastomer, and a thick-film resistor is printed on the back of the ceramic diaphragm to form a Wheatstone bridge (closed bridge).

When the pressure is zero, the bridge is in a balanced state, and the output voltage is zero;

When pressure is applied to the bridge, the deformation of the diaphragm causes the resistance of the four resistances of the bridge to change, and the bridge is in an unbalanced state, generating a highly linear voltage signal proportional to the pressure and proportional to the excitation voltage.

Whether in medical equipment, air conditioning, food & beverage or chemical industry – consistent and reliable pressure measurement utilizing state-of-the-art pressure sensor technology is crucial for a wide range of industrial application.

Ceramic thick film pressure sensor is another major technological innovation of pressure sensor after diffused silicon pressure sensor. The ingenious combination of ceramic thick film technology and simple circuit can produce a new type of sensor with excellent performance and low cost.

Thick-film resistors (including high-temperature wires) can be sintered firmly with ceramic elastic diaphragms without glue. This rigid structure has small creep, small drift, stable static performance and good dynamic performance.

Ceramic elastomers (ceramic diaphragms) have excellent performance, and the flat, uniform, and dense materials strictly follow Hooke’s law within a certain range, without plastic deformation. Thick film elastomers are simple in structure and easy to produce.

The structure of the ceramic thick film pressure sensor is resistant to the corrosion of liquid or gaseous medium. It does not need the conversion and isolation of stainless steel diaphragm and silicone oil, and the packaging structure is simplified to further reduce the cost. The working temperature range is wide, up to -40℃~120℃.The working range is also wide. The measuring range is determined by the ratio of the effective radius to the thickness of the ceramic diaphragm. As long as the micro pressure is not less than 1Kpa, a higher measuring range is also available in principle.

Advanced ceramics are ceramics with high-purity, ultra-fine inorganic compounds as raw materials, precise chemical composition, precise manufacturing, processing technology and excellent characteristics.

Advanced ceramics are divided into structural ceramics and functional ceramics according to their properties and uses.

Structural ceramics are materials characterized by high strength, rigidity, high toughness, good wear resistance, high hardness, fatigue strength and other mechanical properties. They have excellent mechanical properties, thermal properties and chemical properties, and can be used for wear-resistant parts, heat exchangers, seals, cutting tools, etc.

Functional ceramics are materials characterized by physical properties such as sound, light, electricity, magnetism, and heat. Functional ceramics have special properties and exercise special functions. They can be used in the fields of microelectronics, information, automatic control, intelligent machinery, and biomedicine.

We have been engaged in advanced ceramics design, manufacturing and marketing since 2005. We are supplying ceramic parts made from alumina, zirconia, aluminium nitride, silicon nitride, steatite, cordierite and mullite, etc.

We also offer items that may not be listed on this website, such as semi-conductor part, end effector, rod, cone, ray tube, auto part, relay housing, diaphragm ring, vent plug, crucible, vacuum tube, flow-meter gauge, filter, blade, sealed vacuum switch tube, windows, and metalized vacuum tube.

Should you have the need for an item not listed on this site, please contact us and well be happy to assist.

We do offer custom production services for new guides however minimums and tooling will apply.
