Any of you guys with data loggers found a cheap source for 0-5Vdc pressure transducers?  Also looking for hall effect sensors as well.  And I still haven't found a cheap source for k thermocouples either?

If you want a low pressure absolute there are some GM sensors that should work. 0-30"Hg absolute pressure. Would work for manifold vacuum or crankcase vacuum or hood scoop pressure. I had an extra one I plan to use. I could get the number if you'd like.

Are you wanting individual t/c's or one for each side in collector?

Rick right now I'm trying to find out what I can use from aftermarket so I'll know what other stuff I'll have to get from Innovate.  I went looking at pressure transducers this afternoon and boy, they sure are proud of those things every where I found them!  None under $200, that I saw anyway.  They (Innovate) have to be getting them from somewhere and they are selling them for $110 and making money.  There just has to be some somewhere cheaper than that.

I'll need 4 thermocouples to begin with as I won't be able to go with all eight up front.  I'll add the others next winter.  The logger kit I'm looking at right now has 1 LC-1 O2 sensor, which is all I figure I'll need.

Right now I'm shooting for drive shaft RPM, engine RPM, fuel pressure, O2, 4 EGTs, two axis G meter and MAP.

If there are some sensors aftermarket that will work and are cheaper then I may be able to swap those out of the kit for something else that isn't offered.  

You know me, I'll squeeze a nickle until the buffalo farts! =;

So what you are saying is, that if you put a nickle in the crack of your ass, you could walk it down to a dime?  

That's what I thought you said....... =;

Heh, that post was made back in 2004?  

75lb is kinda between where it needs to be.  It's too much for fuel and not enough for oil?  The sensor needs to operate at about 75% of scale.  The price was good though!  ;-)  

Duan PMed me about Bill and is going to check to see what he has now.  

Thanks Mark.

2004 is the date Bill joined that site.

The post was made in December. I will be contacting Bill and see what he has.

If you like to hunt for electronic gadgets these guys are always fun.  Electronic surplus.  We used to hang out there all the time.  They're in Pasadena but as you'll see they have an online store and Ebay some stuff.

Do they need to be plug in compatible? or are you willing to do some soldering to make something work?

A MAP sensor for my car is about $45 and is 0-5V. I am sure it would need adapted to their connector or however they hook up.

Here is a link ...

I'll look at some catalogs at work and see what I can find for the others.

Rick the connection isn't a problem.  I can solder and make up pigtails if needed.  

I went thru the McMaster Carr catalog last nignt and found plenty of high dollar stuff.  Also did a Google search and found plenty but again, the price was thru the roof.

I guess at this point, the main thing is the hose clamp mount type K thermocouple.

Ken I found a cheap source on the hall effect (rpm) sensors but they charge extra if you don't meet the minimun order and I think they will only sell to a business.  I will pm you the info and you can check it out. They handle transducers too but I haven't had a chance to figure out which ones you will need.
