    Universal pressure switches.

    I just purchased a fieldpiece sdmn6. I want to start using universal pressure switches to avoid go backs. How do people feel about universal pressure switches. Does this void warranty? I appreciate everyone's input just trying to save the company time and money, but want to do things right as well. Thanks

    I don't see why it would void a warranty, because how would the mfr know?

    Tried to get prior company to do this,but they are stuck in the past.

    As long as you can set them up properly, I don't see why it would be an issue. You could also just use it as a temp until you returned at a more convenient time.

    Many of the newer equipment have dual p.s., so keep that in mind.

    I have the same set up Fieldpiece sdmn6. I have a pressure switch dial in at .50 but have not used it in the field yet.I don't see a problem as long as you have the proper instruments to calibrate the pressure switch.

    And if you know the setting of the one you are replacing. I keep one in the truck for emergency but most of my calls are 20 minutes at most away so I'd go back with an OEM at some point. I guess my thought is that with a pressure switch if something bad happened I want my butt covered with the oem. It's a pretty crucial safety control.

    Just checked out a youtube on that instrument. In doing so I saw some vid by that Gray guy who keeps posting vids for homeowners to get themselves in jams with furnaces. Anyway he claimed that Trane will not assume liability with any non OEM pressure switch.

    Well now I am thinking I "need" a new tool, probably don't "need" it but I think it would come in handy to know exactly what the switch is set at!

    The best part of the manometer is that you can test the original switch and KNOW exactly at what pressure it is opening and closing because of the hold function.
    Yes, I've seen that before and it doesn't mean I like it.

    Theres no problem adjusting your own. Id say its the easiest thing to do. Also keeps inventory down because you only need 1 switch

    If it is working, otherwise you need to know from mfr.

    How do you know that your electronics are calibrated proper? Do you ever check it against a water column manometer? Why not just use real water in a tube with a ruler to remove all doubt? Or the Dwyer red formaldehyde liquid in their stuff.

    Yeah, I know. Just call me a dinosaur. All I'm saying is that all you need is a dollar's worth of clear tubing to do the same thing. And it will always be calibrated.

    I have used them for a couple of years and think they're great! I set them against a magnahelic. I take specific steps to ensure they operate the same as OEM, and to make them tamper proof after setup.

    I listed it all out, then saw the open forum...

    Had a universal stick closed on me two days after installation. It was one of the newer style with the marked dial indicating setpoint. Prefer the allen head, .18"wc/turn types-smaller, easier to mount and have never had a problem with one. In either case always check setpoint with manometer.
