    Refer gauges going ?

    Why are we not going to wired pressure transducers for our pressure/temperature measurements?

    Add a tee and ball valve and we have all we need. Am I missing something here or should I patten this obvious trend in the industry?

    Hoses are UN-needed anymore, IMO

    What say you?

    How you gonna gas and go?

    I agree to a point, but the majority will need gas added, recovered etc so that would mean another trip to get gauges with hoses.

    Now, I do have a cooper multifunction that has wired xducers for gauges that I use daily, very nice unit, but rarely do I use it only.

    So your patent is out, Cooper already has one and its been out for a while, I may add I have spent around 2k on it.

    I'm onboard with an idea like this.

    Give me a series of sensors connected via wireless.

    Not just transducers and temp sensors, either. That's just the beginning.

    Airflow sensors.
    RH/WB sensors.
    Voltage/amperage/wattage sensors

    Heck, there are probably sensors out there that I would love to have, but don't even know about.

    Let me configure the data view and combinations (SH/SC, delta T/delta P) as I see fit on a PC/Tablet screen. Let me log the data and be able to manipulate it mine it as the job requires.

    There's a difference between working on a residential unit and a rooftop unit. A chiller and a rack.

    Give me the flexibility to build an instrument set that suits the job that I do, change it as the requirements of my job change.

    I have realized all these boards in a simple condensing unit is why god invented side cutters

    Cooper already has a similar device, xducers, temp, s/h and s/c, airflow ,rh, data logging etc.

    Something like this times 2 or more that fits in a tool pouch http://www.fluke.com/Fluke/usen/HVAC....htm?PID=56634

    Add in a tee on each...

    Then I only need a single hose for my suckalater and 2 for the recovery...

    All other service work needs no hose.

    Better yet I would not even an additional tool for my suckalater to measure microns.

    Program in the gasses and walla SH SC etc.

    No lost gas and it fits damn near in my pocket...

    I bet it comes and I bet it comes soon

    The Cooper MFM300 uses wired pressure transducers.

    In the mid/late 90's Robinair made a a refrigerant gauge with wired pressure transducers, but they had severe issues with transducers failing. I went through 6 or 7 transducers in 2 months before United just started giving people their money back on it. Was >$500 for the setup 15ish years ago.
    If more government is the answer, then it's a really stupid question.

    Like everything else like this, we are there and the pricing is there, IMO.

    2 years tops and it will be the new cats meow.

    I have a wireless tool with no hoses I use to check pressures. Whentn got me a tire pressure Gage. Just pop it on the suckin line and when it's under 60 just add some freezon. Whal it's just like a tyre.

    Sometimes we do, do DUI/PUI check points here
