Digital Manometer Recommendation

[jdenne6]

Myself and my team are currently looking to purchase a digital manometer (approx. +- 3-5psi (20-34 kPa)) to be used in our wind tunnel. I was wondering if anyone has come across any particular manometers that work well with LabVIEW, either featuring direct LabVIEW plug-ins or are just better suited for the program. Most manometers I've come across have USB or RS-232 computer connections along with their own data logging software. In the case there are manometers that can be ported directly into the PXI (preferably through BNC), we currently have a NI PXIe-1071 with NI PXIe-8381 and NI PXIe-4492 (with BNC ports) modules. Any recommendations or guidance would be greatly appreciated. Some current manometers I am looking at are listed below.

Traceable 3460 Traceable Digital Manometer with Calibration; ±5 psi from Cole-Parmer Canada (coleparmer.ca)

ExTech HD750 Extech Low-Pressure Differential Manometer - Cole-Parmer Canada (coleparmer.ca)

Mensor CPG2400 Digital Pressure Gauge - CPG2400 - Mensor

Our airflow tunnel uses manometers from MKS.  I didn't personally interface them with LabVIEW so I can't give you any feedback in that regard.  However, I think they output a voltage/current signal that can be read with any DAQ card and scaled to the proper units.

Thank you for the response. These are a good suggestion but might be a little out of our initial price range. I'll definitely have to dive a little deeper into the integration using a DAQ card.
