Underwater data acquisition project

  1. Feb 21, 2010 #1
    I'm currently working on a project where I am required to measure the load that is applied to a chain, which is submersed in an underwater tank (approx. 20 feet). The entire assembly must be self contained and hermetically sealed for up to 6 months.

    I've successfully sourced some good ip68 load cells and a datalogger, however I'm trying to figure out the best approach to enclosing a 24v power supply needed to power my sensors.

    Does anyone have any experience working with electronics underwater? I can't seem to find much info on some good ip68 enclosures that will allow a cable port.

    The most idealsolution would be a self contained 24v power supply that would consist of a box with two wires coming off of it.

    Thanks for any help,
    -Sean

    Someone around these parts may have a better answer for you but have you tried looking in a dive shop to see what they have? I know they have big underwater battery packs for things like flashlights. Maybe you could use one of those.

    Okefenokee: Most of those underwater battery packs are way too large for my application

    Stewartcs: thanks for the info about ODI, I've been looking into what Seacon had, having more options is always a good thing

    I found a really neat lithium polymer 14.8v dc source IP68 all the way....Unfortunately, the company has not decided to make them, I guess their just gauging interest
