Are you in the market for feedthroughs but unsure whether to choose a hermetic feedthrough or a standard feedthrough? In this article, we will delve into the main differences between these two types of feedthroughs to help you make an informed decision.
Understanding Hermetic Feedthrough
Hermetic feedthroughs are designed to create a completely airtight seal, preventing any air, gas, or liquid from entering or exiting the system. These feedthroughs are commonly used in applications where leak prevention is crucial, such as medical devices, aerospace equipment, and vacuum systems. The hermetic seal is achieved through welding, brazing, or soldering the feedthrough to the wall of the system, ensuring a secure and reliable connection.
Exploring Standard Feedthrough
On the other hand, standard feedthroughs do not provide the same level of air-tightness as hermetic feedthroughs. While standard feedthroughs are still effective in many applications, they may not be suitable for environments where leak prevention is essential. Standard feedthroughs are often secured using O-rings or gaskets to create a seal, which may not be as reliable as the welded or brazed seal of a hermetic feedthrough.
Key Differences
- Sealing Method: The most significant difference between hermetic feedthroughs and standard feedthroughs is the sealing method. Hermetic feedthroughs use welding, brazing, or soldering to create an airtight seal, while standard feedthroughs rely on O-rings or gaskets.
- Leak Prevention: Hermetic feedthroughs are designed for applications where leak prevention is critical, such as in medical devices or vacuum systems. Standard feedthroughs may not provide the same level of air-tightness and may not be suitable for such environments.
- Reliability: Due to their welding or brazing sealing method, hermetic feedthroughs are generally more reliable than standard feedthroughs. The secure seal of a hermetic feedthrough ensures long-term performance and minimal risk of leaks.
- Cost: Hermetic feedthroughs tend to be more expensive than standard feedthroughs due to the additional manufacturing processes required to create the airtight seal. However, the reliability and performance benefits of hermetic feedthroughs may justify the higher cost in certain applications.
Which Feedthrough is Right for You?
When deciding between a hermetic feedthrough and a standard feedthrough, consider the specific requirements of your application. If leak prevention is paramount and you require a reliable, airtight seal, a hermetic feedthrough may be the best choice. On the other hand, if cost is a significant factor and leak prevention is not a critical concern, a standard feedthrough may be sufficient for your needs.
In conclusion, hermetic feedthroughs and standard feedthroughs each have their advantages and are suitable for different applications. By understanding the key differences between these two types of feedthroughs, you can select the option that best meets your requirements for performance, reliability, and cost-effectiveness.
when it comes to hermetic feedthrough vs standard feedthrough, it all boils down to your specific needs and priorities. Whether you prioritize leak prevention, reliability, or cost, there is a feedthrough that is right for you.
