InSealing focuses on the development and production of ceramic vacuum feedthrough for many years.
Vacuum feedthrough can be connected to a variety of devices that need to transmit signals or energy in a vacuum or high pressure environment, the main role is to transmit signals or energy in a vacuum or high pressure environment, the main principle is to use the electric field effect between the metal tube and the electrode to transmit signals or energy to the target device.
It is also called vacuum point feed through, vacuum through the seal. As a kind of sealing device that can transmit various electric power and telecommunication signal at the atmospheric end to the vacuum chamber through the vacuum chamber wall, it is widely used in electric vacuum devices.
The structure of vacuum feedthrough is generally composed of three parts: feedthrough body, insulator and connector. The feedthrough body is generally made of stainless steel, titanium alloy or ceramics and other materials, and its main role is to lead the conductor or pipeline in the connector out of the vacuum chamber. Insulators are used to isolate electromagnetic interference and gas leaks between feeders and conductors or pipes, and are typically made of materials such as quartz, ceramic or plastic. The connector is used to connect the feeder to the conductor or pipe, and to ensure tightness. The InSealing insulator is made of 96% ceramic.
In the vacuum system, the vacuum feedthrough can be used to transmit various signals and energy, such as electrical signals, electricity, heat, gas, liquid, etc., which is widely used.
Power transmission: electrical feedthrough can transmit power without the need for wires. This technique is commonly used to transmit high voltage DC power. Because electrical feed-through does not require metal wires or insulators, it reduces energy consumption and wire costs.
Communication: Vacuum feed-through can be used to transmit radio signals. This technique is commonly used for satellite communications and radio channel testing.
Fluid transfer: Vacuum feedthroughs can be used to transfer gases or liquids, especially in environments where high levels of cleanliness or contamination need to be avoided. For example, in semiconductor manufacturing, vacuum feedthroughs can be used to transport highly pure gases.
Laboratory applications: Vacuum feed-through is also widely used in physics laboratories. For example, in the laboratory, vacuum feedthroughs can be used to transport gases or liquids in experimental installations, as well as to transport high-energy particles such as particle beams and radiation beams.
In the field of scientific research, vacuum feedthrough can be used in various experimental devices in vacuum chambers, such as mass spectrometers, electron microscopes, lasers, etc., to transmit data and control signals.
