Druktransmitters En Druktransducers Druktransmitters en Druktransducers www.keller-holland.nl Produktlijn Overzicht MathMod Compensatie: Mathematische modelle- ring van de sensorkarakteristieken die nauwkeurige compensatie mogelijk maakt met een standaard uit- gangs-signaal als resultaat. Afhankelijk van de complexi- teit van de modellering of de compensatie algorithmes, is dit uitgangssignaal nagenoeg vrij van temperatuur invloeden en lineariteit fouten. CiO-Technologie: Bij chip-in-oil technologie wordt de signaal conditioneringschip in de met olie gevulde be- huizing van de drukmeetchip geplaatst. Omdat er geen externe elektronica nodig is, is een compacter ontwerp van een geconditioneerde druksensor mogelijk, en zijn deze sensoren uiterst goed bestand tegen externe in- vloeden zoals vocht, trillingen, schokken en EMC.

  • Inert Lubricants Oils – Greases – Waxes Halocarbon Inert Lubricants
    Inert Lubricants Oils – Greases – Waxes Halocarbon Inert Lubricants Halocarbon oils, greases and waxes are polychlorotrifluoroethylenes (PCTFE), which are chemically inert and nonflammable lubricants with high thermal stability, good lubricity, high dielectric strength and low compressibility. Halocarbon was the first to commercially produce PCTFE-based lubricants over 60 years ago. We offer a wide range of oils, greases and waxes to meet industries' needs. The inertness of our lubricant is required for the safe handling of highly reactive and/or aggressive chemicals like oxygen, chlorine, hydrogen peroxide, sulfur trioxide and nitric acid. This unique chemistry can also provide advantage in many other applications from lab-scale to the production plant. Have Questions?

  • NASA Technology Roadmaps TA 6: Human Health, Life Support, and Habitation Systems
    NASA Technology Roadmaps TA 6: Human Health, Life Support, and Habitation Systems May 2015 Draft 2015 NASA Technology Roadmaps DRAFT TA 6: Human Health, Life Support, and Habitation Systems Foreword NASA is leading the way with a balanced program of space exploration, aeronautics, and science research. Success in executing NASA’s ambitious aeronautics activities and space missions requires solutions to difficult technical challenges that build on proven capabilities and require the development of new capabilities. These new capabilities arise from the development of novel cutting-edge technologies. The promising new technology candidates that will help NASA achieve our extraordinary missions are identified in our Technology Roadmaps. The roadmaps are a set of documents that consider a wide range of needed technology candidates and development pathways for the next 20 years. The roadmaps are a foundational element of the Strategic Technology Investment Plan (STIP), an actionable plan that lays out the strategy for developing those technologies essential to the pursuit of NASA’s mission and achievement of National goals. The STIP provides prioritization of the technology candidates within the roadmaps and guiding principles for technology investment. The recommendations provided by the National Research Council heavily influence NASA’s technology prioritization. NASA’s technology investments are tracked and analyzed in TechPort, a web-based software system that serves as NASA’s integrated technology data source and decision support tool. Together, the roadmaps, the STIP, and TechPort provide NASA the ability to manage the technology portfolio in a new way, aligning mission directorate technology investments to minimize duplication, and lower cost while providing critical capabilities that support missions, commercial industry, and longer-term National needs.

Johnson Space Center, Houston, TX, 77058 and Eric Falconi4, Bruce Barnes5, Bruce Conger6 Jacobs Engineering, JSC Engineering Technology and Science (JETS), Houston, TX, 77058 The Variable Oxygen Regulator (VOR), a stepper-actuated two-stage mechanical regulator, is being developed for the purpose of serving as the Primary Oxygen Regulator (POR) and Secondary Oxygen Regulator (SOR) within the Advanced Extravehicular Mobility Unit (EMU) Portable Life Support System (PLSS), now referred to as the xEMU and xPLSS. Three prototype designs have been fabricated and tested as part of this development. Building upon the lessons learned from the 35 years of Space Shuttle/International Space Station EMU Program operation, including the fleet-wide EMU Secondary Oxygen Pack (SOP) contamination failure that occurred in 2000, NASA is analyzing, designing, and testing the VOR for oxygen compatibility with controlled Non-Volatile Residue (NVR) and a representative worst-case hydro-carbon system contamination event (>100 mg/ft2 dodecane). This paper discusses the steps taken in testing of VOR 2.0 for oxygen compatibility, and discusses follow-on design changes implemented in the VOR 3.0 (3rd prototype) as a result.

F.3.3.8 2 of 16 6/5/2015 2:42 PM National Fire Protection Association Report http://submittals.nfpa.org/TerraViewWeb/ContentFetcher?commentPara... The oxygen index test, ASTM D2863, and variations of it have come into wide use in the last few years for their characterizations of the flammability of materials. In the ASTM procedure, a small, vertically oriented sample is burned downward in a candle-like fashion in an oxygen-nitrogen mixture. The composition of the gas mixture is adjusted to determine the minimum percent of oxygen that will begin to support combustion of the sample. This minimum oxygen concentration is called the oxygen index (OI). Burning in an upward direction can take place more readily and produce a lower OI. The OI test, as determined by ASTM D2863, is limited to nonmetals (e.g., plastics) at ambient pressure. However, the OI concept is now utilized at elevated pressures (and temperatures) and for metals as well as nonmetals (see F.3.4 for the OI data of metals) . Other means of ignition have also been used, as have other oxidants and diluents. (44, 45) Conceptually, an OI is a flammability limit but is more complex than the flammability limit for gas mixtures. Therefore, the OI is only one of several criteria that can be utilized to evaluate the suitability of materials for a specific oxygen application.
