Diagnostic Port Specifications
The line of diagnostics port designed and produced by LumaDyne fill the gap between high and low pressure system diagnostic tool process chamber adaptation. Many processes require an extreme variation in pressure to obtain the resultant product. Processes that incorporate a vacuum cleaning procedure into a high-pressure process require extra ordinary design. Our line of Diagnostic Ports adapts any type or sensor or feed through in extreme process chambers and vessels.
Tools
Many different types of instruments maybe required on several different chamber configurations, especially for R&D and other types of parametric studies. To decrease the amount of required hardware for such studies we have created an interchangeable diagnostics core insert that is easily removed and reinstalled in a larger chamber adapter. This insert can hold any type of diagnostic hardware sized for the insert. Typically the smaller inserts are used for instrumentation such as temperature, pressure and fiber optic coupling. The larger and non-round inserts are typically used for spacially resolved photonic information, RF and flow diagnostics. The object is to match as many diagnostic tools as possible to a minimal number of chamber adapters using these inserts. When reconfiguration of the process is needed the only modifications required are removal of the current tool and replacement with a different one, the seals and geometry to the chamber remain the same.
Geometry
To obtain more precise and reliable results from any flowing or active process the tool must remain as non-invasive as possible. We have design a base model port that allows it to be easily adapted to these environments. Our ports can be specified to impinge on the flow, contour to the chamber surface or supply a sampling reservoir. Different chamber adapters while maintaining similarity across each tool insert can provide each method of contoured detection.
Exotic Materials
Due to the extreme nature of some processes we have adapted methods of producing and handling materials that are sometimes considered exotic. Insert and adapter construction materials can range from standard Stainless Steel and Aluminum to Solid Quartz and machined ceramics and plastics. The idea is to match the port to the material used in the construction of the vessel to minimize contamination and otherwise skewing of data retrieved via these diagnostics ports. Other exotic materials may be used in the construction of these diagnostic ports for spectroscopy, laser radiation and RF radiation handling. Many optical windows are many from materials such as sapphire, Magniesium Fluoride and Zinc Selenide. Other feed through materials may consist of custom alloys and/or pure metals such as gold and nickel.
Testing
All diagnostic ports built are tested for their exact pressure, vacuum and temperature rating. Other specific ratings may include radiant heating and pH. Pressure tests are performed via hydrostatic test when liquids are permitted for use with material type helium leak checking is used for vacuum testing. All parts are solvent cleaned and baked before shipping. |
