    Simultaneous measurement of voltage by two computers

    Hello everyone, For a test bench we're finalizing, we have a few sensors (PT, TC, etc...) that are amplified to -5/5V by Delmation modules, multiplexed and recorded on a computer by an ADLink PCI card. As some of these measurements are critical, we need to double the recording devices (the...

    High pressure vessel

    Hello! I'm currently working on the design of a relatively high pressure vessel: a 20cm-inside-diameter and 45-inside-height vessel containing 1000bar oxygen. My goal, here, is to make my own idea of the beast first and to evaluate grossly its cost. Fully detailed design would be contracted...

    Rapid valve opening, Adiabatic compression and Oxygen

    Hello everyone! I'm currently on a project involving the oxygen compatibility of alloys. We are building a experimental setup which looks will recreate an quasi-adiabatic compression of oxygen onto a piece of metal (and see if it burns, or not). The setup looks like this: 1000bar vessel...

    Condensing methane by nitrogen vaporization

    Hello everyone! I'm currently working in cryotechnics and would need a new liquid methane line. We're investing the possibility to use our stock of Liquid Nitrogen to liquefy Methane coming in bottles (180bars). [Note: this project is temporary, so we'd like to go as low-cost as possible] Thus...
