Faria gauges with Sierra sender... possible?

[basssears]

OK, my head is starting to spin here so thought I'd see if anyone knew the answer to this.

On our pilothouse we have gauges only down in the cabin. I want to mount a water temperature gauge up in the cockpit as well so I can see engine temp anytime.

We currently have 2" Faria gauge in the panel down below. I would LIKE to keep that gauge style and just get another Faria 2" to mount in the cockpit.

BUT, I can't tell if I'm finding a sender that would work with Faria gauges or not. Faria does not make (AFAIK) a dual sender that is 1/4" NPT, which is what I have to work with (really don't want to drill and tap this to 3/8", but I guess that's a possibility). I have found a Sierra 1/4" NPT dual sender but can't tell if it's compatible, because I can't find any resistance ranges for the Sierra sender (found Faria resistance chart: http://www.overtons.com/assets/prodman/IS0085E.pdf)

Anyone know a way of finding out if this sender is compatible? Or am I stuck using senders and gauges from same manufacturer only (in this case I guess I would go with Sierra gauges then)?

Currently have something that APPEARS to be a Faria Chesapeake SS gauge, but even if that's not what I have currently for $34 I'm willing to buy two and replace one in the pilothouse.

So... long story short (too late), could I buy two of these Chesapeake SS 13804 gauges:
Products - 2" - Temperature gauges
... and use this Sierra TS26651 sender:
Amazon.com : Sierra International TS26651 240 Degree Dual Station Marine Temperature Sender with NPT Thread & Terminal Type 10-32 Stud, Size 1/4-18 : Boat Compasses : Sports & Outdoors

Any ideas?

Thanks in advance,

My idea would be to attach an n2k interface to the engine panel and use a multi-function display wherever you need read-outs. Raymarine, Garmin, Furuno, B&G, Simrad, Maretron and about every other brand have a suitable display. Actisense has the interface box.

I think, from the pics on that link, those SS 13804s are NOT "Chesapeake" gauges. Chesapeake gauges would look like this: http://faria-instruments.com/styles.php

Happens I have two Chesapeake temp gauges that I've replaced, if you end up being interested in that. (They work fine; I'm just gradually replacing all our analog gauges with digital.)

The question about senders will come down to what resistances they pass at various temp levels. Call Sierra and ask?

The Faria gauges will likely "work" with any sender; it'll be about whether they are usefully accurate or not.

I say that because during my changeover from analog to digital, I discovered a mis-match. Our engine coolant temp senders as delivered (VDO) should have been replaced with something like Teleflex. All that time, I thought the gauges were wrong, since they always -- at least consistently, though -- showed much lower temps than our engines like. Turns out when I installed the digital gauges and chose the expected sender setting during set-up, they too showed almost exactly the same temps the Faria gauges displayed. A little sender examination solved that...

Sierra Tech support: 1-877-663-8396.

Dual station senders have 1/2 the resistance value of the single station senders.

Right you are, although the Chesapeakes are listed on this page I linked to the images at the top aren't representative, your link is... that's the exact gauge I currently have in one spot.

You should be able to get a 3/8 to 1/4 adapter for the sending unit rather than drilling.

Here is Sierra/Teleflex sender info. Check it against what you need.

Thanks Gord... not sure why it never occurs to me to ask manufacturers directly, probably have some bad experience in my past

And thanks for the info on the resistance for dual senders... so far my research is showing the Sierra sender won't work, but I have contacted Sierra and Faria and will see what they say.

Thanks, if you're aware of one I'd certainly appreciate the link. I ordered one before and while the female side was threaded for 3/8" and the male side was threaded for 1/4", the male end (1/4" end) was too small for the sender to fit into so it wouldn't work.

Thanks... been confused on this, are Sierra and Teleflex the same?

Seems like the Teleflex sender might work with the Faria gauges:
Faria sender values: 100F = 450 ohms, 175F = 99 ohms, 250F = 29.6 ohms
Teleflex sender values: 75F = 600-800 ohms, 212F = 55 ohms
(Comparing single sender values, know the duals are 1/2... or I know that now)

Sorry wrong charts. Here they are attached.

Nothing attached to this reply?

[Squanderbucks]

Here is Faria spec sheets from their website and it appears the OHMs range is different so a Teleflex/Sierra would not work.

[Squanderbucks]

Senders for Sierra/Teleflex data. Sorry closed upload window too soon.

[basssears]

Thanks everyone for the help, hopefully this will help others if they search on it.

Got confirmation from the Faria folks that the Sierra senders are actually made by VDO and WILL NOT work with Faria gauges.

So I guess I need to just change out the Faria gauge for a Sierra and hope it doesn't look too funny, then put second Sierra in cockpit.

Sigh.
