Digital barometer recommendations for use with LabView 8.0

[thomas_p]

Hi,

Can anyone recommend a digital barometer that can be integrated with our existing data acquisition system and LabView 8.0 to provide real-time updates/readouts of the ambeint pressure?

Our data acquisition hardware consists of a NI cDAQ-9172 8-slot USB 2.0 chassis. This has three modules currently connected into it, a NI 9211, a NI 9481 and a NI 9205.

Thanks for the help.

Hi Thomas,

Vaisala builds very nice barometers

But with your 9205 you could use any barometer with a voltage or current output signal...

Hi GerdW,

Thanks for the reply - I will look into it.

Are there any NI-specific barometers/pressure sensors that would work with my setup?

Hi Thomas,

I don't think NI will supply you with pressure sensors.

There are so many companies selling pressure sensors, mostly with common ratiometric (voltage) output, so you should start a simple G**gle search...

I have tried Googling previously but it comes up with many hundreds of results, hence why I'm asking if anyone has any recommendations. I am looking into the Vaisala units, but the lack of obvious pricing on their website is a slight deterrant, especially as this is for a budget-concious project.

Hi Thomas,

Vaisala devices will maybe let your budget "explode" - but they are very precise and show a fancy LCD display 

As you haven't said any specifications (price being one of them) you cannot expect any more detailed hints...

Simply grab the next phone and call one (or more) of the distributors/manufactures (like SensorTechnics)!

Specification-wise, we don't really have much! We don't need a display on the device as it will be directly integrated into a Labview VI (so that is another requirement, ease of integration with existing NI hardware), and cost must be "reasonable" - I can't give an exact figure though at this stage. We can't go spending thousands on this, I'd guess a couple of hundred pounds, including VAT & Delivery would be the limit.

This one you might get as a free sample. You asked for digital?

Simple consumer barometer in MEMS technology are quite cheap and many semiconductor companies have some in production.
