'[OT] Pressure Sensors'

Hi all,
I'm looking for a low cost pressure sensor (smd) (about $1.00 each quantity
5000) to be used in a consumer product.  It doesn't need to be accurate +/-
1 psig is okay.  Does anyone know where I can get such a sensor?  I've been
looking at the Lucas NovaSensors (NPC-103).  Not sure what the price
is...all my vendors are home eating supper and getting ready to watch the
Boston Bruins.

Hi Jeff, I sure wish I could help you. I've been looking for exactly the same
think for at least a couple of years. So far, the closest thing is about
$2.50 USD for a device with poor specs for linearity and tempco, and a
millivolt output that has to be amplified to be useful. And that's in
nearly carload quantities.

So if you find something, I'd really appreciate your sharing it!

Reg,
I'll keep you posted on what I find.  What was the sensor you found for
$2.50?

A good pressure sensor is the Honeywell PC140.  I was able to get a
few through surplus for $2.50 each.  This was a few years ago and I
haven't seen them since.  But I'd still recommend looking for the
PC140.

Made by Fujikura. US Rep is Servoflo Inc. Call 617-862-9244 and ask for
David Ezekiel. Onesies price was more than three times as high, as I
recall. There are comparable parts by Sensym and Motorola that are somewhat
more expensive, and all three companies make devices with built-in opamps
for 0-5V compensated output, but those are WAY more expensive. Also, my
application can only budget a couple of mA or less, and the high-level
output devices use 10 or 20.

Good Luck,
Reg
