Source for sending-unit style pressure gauges?

[MChalkley]

I'm looking for a source for gauges for my next customization project - the EarthForce EF-5. If possible, I'd like some transducer-style units that send both pressure and temperature electrically. Any suggestions?

Also, does anyone know what style of tachometer Kubota uses? (I've already given away my shop manual and I don't remember.) The EF-5 uses a Kubota 56hp engine and supposedly includes the sending unit - I just need a tach that'll work with it.

There's an outfit in North California (I think /w3tcompact/icons/crazy.gif) called Westach that has a wide assortment of instruments and sender units for aircraft. Since most aircraft use tractor motors that were designed in 1940 or so, that ought to be a great place to go.

You might also want to check out Aircraft Spruce and Specialty (Fullerton CA last I checked).

AS&S sells a tach/sender combo that uses a dynamo/sender combo to send the engine speed to the tach. I have one on my EZ, since the engine is in the wrong place (relative to other airplanes), and running a mechanical linkage caused me to have nightmares. /w3tcompact/icons/crazy.gif

Glueguy it wouldnt be the CRS acting up would it/w3tcompact/icons/smile.gif But you are right they will also make gauges for any application.

Mark Click Here They are very reputable and very nice people/w3tcompact/icons/smile.gif and you can also order thier free catolog and price guide off the internet.

Mark,

Click here SendersTeleflex, Staurt(sp) Warner and many others make "senders" and gauges for water and oil Temp, Vacuum pressure, oil pressure ect. Marine supply places like Boat US,
West Marine will have them.

Some very interesting sites, guys. Some good ideas for the engine performance gauges there. Thanks! None of them offer pressure transducers for hydraulic pressure applications, though. Any ideas for that?

FWIW, I'll be starting the long-expected (if not anticipated /w3tcompact/icons/laugh.gif) "EarthForce EF-5 enhancements" thread shortly, in which I'll detail the things I've got planned so far, subject to change after I actually get it and use it, of course... /w3tcompact/icons/wink.gif

Mark,

There are lots of precision pressure transducer in the 1000 to 4000 psi range available. The rub is they cost about as many dollars as they measure psi. Here are a couple of links to give you an idea.
Endevco Omega These are the 0.1% kind of transducers, I think your looking fo the 2% kind that cost $25. If I stumble across some I will let you know.

Thanks, Al. The Omega site has some interesting ones in the $400 range, but even at that price none of them offer temperature as well.

Thanks for keeping on the look-out for something. Even 1% at $50 would be great! /w3tcompact/icons/laugh.gif

Check my post on your EarthForce EF-5 enhancements thread. Bob

Check out Digikey http://www.digikey.com They have some $70 1-5V @ 5000psi pressure xducers by MSI. Just use a thermocouple or a transmission temp gauge for temp
