Post by thread:[EE] Sensor for pressure

I would like to continuously monitor the differential pressure between the interior and exterior of a balloon. I expect the pressure to run between 0 and 10 inches of water. I will be using a micro controller to drive the application. What sensor would be optimum for this? Any enlightenment will be appreciated.

Check out Freescale's and Honeywell's differential pressure sensors, which are relatively low cost. One example is the MPX4250DP, which may be a good fit for your app. Cheers, -Neil.

One example is the MPX4250DP Wrong pressure range. I believe this is made for barometric applications. *____________________________________________________________________________________________* *Victor Fraenckel KC2GUI victorf ATSIGN windreader DOT com** * PicDude wrote: > Check out Freescale's and Honeywell's differential pressure sensors, which are > relatively low cost.

Honeywell DCXL range will do the job (and then some). -marc On 12/1/06, Victor Fraenckel <spam_OUTvictorfTakeThisOuTwindreader.com> wrote: {Quote hidden}> > One example is the MPX4250DP > > > Wrong pressure range.

Hi Vic, Optimum? I don't know - thats up to you! :) We use a Honeywell 163PC for a slightly lower range (+/-2.5)... They have one that goes 0 - 10 inches as well - see... content.honeywell.com/sensing/prodinfo/pressure/catalog/c15_41.pdf This may do what you need. -- Mark > {Original Message removed}

Freescale makes gauge, differential, and absolute pressure sensors in various pressure ranges, and several output voltage ranges including 0 -5 vdc which interfaces nicely to a PIC and others with 3 little filter caps. Check Freescale's site for stocking distributors, lead time can be long for non-stock. Have bought recently from Digikey, Mouser, and Newark. Their catalogs have good lists, but check stock first.
